Each of us knows the humorial expression "the brakes came up with panties", but everyone remembers that the brake system is the most important in the car and determines its dynamic characteristics. So, any car tuning, starting with an increase in engine power, it necessarily ends with "buildup" of the brakes.
When using a civil car, the owner in a daily bustle often forgets that the brake system needs to pay attention to, follow it and carry out maintenance in time.
Many operations for working with the brake system are simple, and most motorists perform them independently in garage conditions. Knowing your car, improve the quality of the work done is very simple: it is enough to smear in the right place using special chemicals. A large number of specialized auto chemicals for repair and maintenance brake system Can be found in the assortment of the German company Liqui Moly. About how and in what places to use it, and our story will go. Yes, one more reservation: we are talking about disk brakes.
About disk brakes
Introduction
Disc brake systems are two structures: opposite (monoblock) and with a compensating bracket.
In opposite systems, pistons are located opposite each other. In systems with a compensating bracket, the pistons are located on one side of the caliper and are attached to the swivel fist using a separate bracket (compensating). Such caliper are sometimes called floating. The caliper is movable in the direction of the axis of the brake disc and floats on the guide fingers. Such systems were widely distributed and installed on the vehicles of budget and middle levels.
"Floating" caliper.
Inexpensive lightweight design. Used by inexpensive cars both in front and on the rear axle. Can be complemented by the drive manual brakes. Often contributes to uneven wear brake shoes. Requires regular service.
Opposite monoblock caliper.
Durable heavy design. Used on sports or heavy cars, SUVs, motorcycles. It was distributed in the 1970s, now received the second birth. Unpretentious, reliable, not requiring a serious maintenance design.
The maintenance and repair of the brake system of the car includes the following operations:
1. Replacing brake pads and disks.
2. Cleaning and lubrication of brake calipers.
3. Check and replacement brake fluid.
4. Processing adjacent surfaces with non-stick compositions, brake hose protection.
General instructions on the diagnosis of the brake system
One of the diagnostic procedures is to measure the brake disc.
Check thickness overlays The brake pads and states of the pistons of the calipers are necessary with each car maintenance. The replacement of the pad is necessary in the case when it is obvious that the brake pads of the pads are stronger than critical until the next service.
Uneven brake disc wear is the basis for its replacement.
When you need replacement brake discs?
Replacing disksit is performed with a decrease in the thickness of the working surface of the disc is less permissible (measured by the calipel), during critical beyond (the beating is measured by an indicator stronger; see the instruction to the car), as well as with strong corrosion, cracks and other damage. Replacing the brake discs is made only in pairs (both disks are changing on one axis of the car) with simultaneous replacement of brake pads (regardless of their condition).
When is it necessary to check the state of the brake fluid?
Checking the brake fluid condition It is made with each maintenance, but not less often than once a year. Replacement Conditions: The expiration of the fluid operation (see the instruction to the car), a sharp change in the color of the fluid (darkening or cloudy), a decrease in the boiling point of the liquid to 165 ºС and less. Synthetic brake fluids tend to absorb water during operation, which leads to a decrease in the boiling point. The boiling point of the liquid can be measured directly or on the relative indicator - electrical conductivity. The easiest and easiest way is to measure electrical conductivity. The tester has three indicators. If when the electrodes are immersed in the brake fluid, a green indicator is lit, then everything is in order, the brake fluid is fresh. If yellow, then the moisture content is within 1-1.5%, and further operation is possible. If red is burning, then the moisture content of the limit is about 3%, and it should be replaced as quickly as possible.
The easiest way to check the state of the brake fluid using a special tester.
How to replace brake pads?
Treatment of parts solvent rust with molybdenum Liqui Moly. MOS2-Rostloser makes it easier to dormant / disassembly.
In order to quickly degrease the surface, it is convenient to use a quick cleaner Liqui Moly Schnell Reiniger.
With any constructing of the caliper, it is required to process the part with a rust solvent with Liqui Moly MoS2-Rostloser molybdenum. The remedy must be sprayed into fastening parts and seats of brake pads for the ease of performance. On the floating caliper It is necessary to unscrew the lower bolt, which locks the brake cylinder into the bracket. Throw down the caliper up and fix in this position for the pendant details. For fixing it is convenient to use a wire hook.
Next, you need to remove old pads from the guide grooves. Remove the guides of the caliper of the socket. Clear planting pads with a metal brush and spray to the remnants of dirt quick cleaner Liqui Moly Schnell Reiniger. The guide of the caliper and their sockets are cleaned from the old lubricant and completely degrease the quick cleaner. Dry details.
After that, using a clamp or a special tool, drown the pistons of brake cylinders. When jealous or excessive effort in the movement of the pistons, it is necessary to remove the rubber antics of cylinders, remove contaminants and spray the Liqui Moly Silicon-Spray Silicone Spray. After that, it is necessary to swing the piston of the caliper, sequentially squeezing it out of the cylinder using the brake pedal and beating back the clamp. Next, you need to check the ease of movement of the piston and re-spray the silicone spray. Then put the boot back. If it is impossible to restore the operation of the brake cylinder, replace it or repaired with the mandatory polishing (or replacement) of the piston and the replacement of the brake cuff with a padfer.
How to collect disc brakes?
Before installing the brake pads, it is necessary to lubricate their guides in contact with surface pads on the caliper, for which it is necessary to use the synthetic lubricant for the brake system - the Liqui Moly Bremsen-Anti-Quietsch-Spray spray. The same lubricant processed the rear side of the pads and the surface of the anti-slip plates (if they are provided with the package). Lubricate the caliper finger guides and their anti-slip pasteraths for the Liqui Moly Anti-Quietsch-Paste guides (it is necessary to avoid excessive application).
Before installing the head of the caliper's fingers and their anthers, it is recommended to process the anti-slip pasta Liqui Moly Anti-Quietsch-Paste.
To eliminate the brake pad creaking, it is recommended to process the specified points with synthetic lubricant for the brake system - the Liqui Moly Bremsen-Anti-Quietsch-Spray spray.
Next, you need to install items in place and collect caliper. Before twisting the fastening bolts, it is recommended to lubricate the thread with an aluminum spray, or copper paste, or synthetic lubricant for the brake system. After the assembly, it is necessary to cleanse the disk from the traces of the used compositions and from the conservative lubrication using the fast cleaner LiQui Moly Schnell Reiniger.
Sequence of actions when working with opposite calipers is the same. Difficulties may occur only with the extraction of the pads, so it is necessary to use rust solvent with Liqui Moly MoS2-Rostloser molybdenum. Springs and fixing shods Before installation, it is recommended to be treated either by aluminum sprays or copper paste or synthetic lubricant for the brake system.
Important!When working with cars equipped with ABC system, you should use the ABC sensors and their connectors with care. It is necessary to clean the comb with which the sensor reads the wheel speed signal.
How to replace brake dicks?
To replace the brake disc, the rust solvent with the molybdenum Liqui Moly Mos2-Rostloser should be sprayed onto the mating surface of the disk and the hub, into the holes for the heel or bolts. Fully remove the caliper, unscrew the drive screws (if any). Sometimes, for example, "Mercedes" and SUV "Toyota", you have to remove the disk along with the hub and later separating the disk from the hub using the press.
Before installing a new disk, it is necessary to clean the mating surfaces with a quick cleaner Liqui Moly Schnell Reiniger, dried and apply separating lubricant (to choose from: aluminum spray, copper paste or synthetic lubricant for the brake system). The same compositions need to handle fasteners and its adjacent surfaces.
In order to lay the lubricant for the brake cylinder antips, it is necessary to delay the boot with a screwdriver and spray the Silicone Spray of Liqui Moly Silicon-Spray.
It is necessary to lubricate the pads and anti-slip plates. To do this, we need to be lubricated Liqui Moly Bremsen-Anti-Quietsch on the end surface of the pads, as well as the anti-slip plates specified by the surface arrows.
How to replace the brake fluid?
Replacing the brake fluid begins with the selection of the right product. Needed in the instructions for the car to find which product is recommended because modern cars It is quite different from each other, and an individual approach is required. First you need to cope with the instruction manual. Many manufacturers indicate the minimum requirements, such as DOT 3. This fluid can and need to be replaced with a more modern DOT 4, and in the case of a sports style ride - on Dot 5.1. If the manufacturer places special requirements (for example, the last generations of VAG require DOT 4 6 class, and Hammer H1 requires DOT 5), then recommendations should be performed. Comparison of standard brake fluids is given in Table:

For ease of replacement, it is better to use a special installation that ensures the speed and security of the process. We use Pressol Pneumatic Installation. It has a universal adapter for installation on the neck of the brake tank. Filling capacity The installation is 5 liters, which allows you to replace the brake fluid in 4-5 cars without refueling the installation. Installation is compact and does not require electricity, only a pneumatic machine with a pressure of 6-8 atm. After pumping, the installation can be turned off from pneumatic jam and autonomously change the liquid in the car: the reserve of the accumulated pressure is enough.
The procedure for replacing the brake fluid is carried out in the following sequence. First you need to connect the adapter on the brake tank, connect the feed hose to the adapter. Fix 5 liters of brake fluid to installation. Connect the installation to the pneumatic area and set the pressure at the input 6-8 atm. Installation pressure regulator Set the fluid supply pressure not higher than 1.5 atm. Feed pressure shows the top pressure gauge installation.
The brake fluid replacement adapter is screwed up instead of the brake fluid tank tube.
The brake fluid replacement is connected to the pneumatic area, and pressure 6-8 atm is set at its input.
After that, the car rises to the lift, and the wheels are removed from it. If there is a brake force controller on the rear axle, you need to install backups under the bridge or levers and slightly lower the car - so that the regulator passes the brake fluid to the wheeled brake mechanisms. Replacement should be started with the brake line having the greatest length (as a rule, from the right rear wheel). It is necessary to wear a suitable transparent tube on the pump fitting and lower one end to the vessel to utilize the old liquid. After that, it is necessary to include a feling faucet for fresh brake fluid.
Open a groove fitting and merge the old liquid until fresh flows. Fresh brake fluid has a noticeably brighter color. Close the groove fitting, remove the tube, dress the rubber cap cap. Before installing the wheel, lubricate the plane of its fit and fastening with non-stick lubrication or aluminum spray, or copper paste, or synthetic lubricant for the brake system.
For next stage It is necessary to raise the car on the jack and remove the wheels to get to the point of pumping the brake system.
A transparent tube is put on the pumping fitting, the end of which is descended into the vessel to utilize the brake fluid.

Copper lubricant for caliper, to be or not to be? There are so many opinions on the Internet, but often they proceed from people who repair only their car, and even then on the knees of Dedov methods. Let's deal with where copper can be used, and where it is not a place. Let's start with a bright example. Dodge caliber, typical. Presumably zakisili guides, rear axle This sins, however, life is full of surprises.
The car arrived after replacing the rear pads in a third-party service. Many "Mechanozavra" do not unscrew the upper guides, but this time we got a very diligent instance. Over dilapidative. Copper, everywhere copper layers. On the guides, on the reverse side of the pads, on the springs of the brake brake, on the anthers of the brake cylinders and even on their working surface.
Do you think this dirt? In part, yes, but the basis for which it is superbly sitting is a thick-thick layer of chocolate copper lubricant. Instead of smooth slip, an excellent abrasive was obtained.
And now let's admitting what happens inside the caliper - porridge from the brake fluid, copper and dirt. Of course the brakes will be to climb.
But a photo-riddle from the article about.
These two frames cover 90% of all needs. Copper lubricant for the caliper is not used at all, the maximum for the brackets and then under the springs of the pads, and not on them. In all other cases, there are modern solutions, superior copper on the head, sometimes even two. If you do not know what to use, carefully read what manufacturer writes about this in technical documentation, first of all, the manufacturer of your car.
The working surface of the brake cylinders is lubricated extremely rarely, mainly this is a lot of advanced systems, often sports and not accessible to the ordinary user. For guides, an original grease is suitable, or competently selected industrial, the requirements for which much more serious.
Well, do not forget about a simple rule: the abundance of lubricant is not better than its lack, everything should be in moderation.
All car systems during its operation must be good. But some attention must be paid to the brakes. After all, often the life of the driver, passengers, other participants in the movement and pedestrians depends on the state of the brake system of the machine. Periodically, it needs to be serviced. This is to replace brake pads, disks, liquids, as well as calipers. For example, lubricant for brake cylinders when maintaining and replacing is simply necessary. We will talk about all this.
Lubrication guide caliper
Before moving directly to the cylinder, you need to deal with its guides. During operation, there is a large amount of heat. This leads to the fact that the compound is often accompanied by tightly. This also applies to the guides that begin to twist. There is nothing good in this, as this may lead to serious consequences. Sweeping contributes to the fact that the pads will be constantly pressed to the disk. This leads to significant overheating of the system. As a result, the pads are burning, the discs become curves. Yes, and the tire in such conditions can easily light up. That is why when servicing a caliper, it is necessary to process guides with special lubricant. What exactly, we will understand this article.
Properties of lubricant for cylinders and guides
Since the node refers to the hard-loaded and in the process of work heats up to 300 degrees Celsius, and with aggressive ride and above, the approach must be appropriate. Lubricant for brake cylinders should have the following characteristics:
It is based on the above parameters, a grease for brake cylinders and guides should be seamless. Fortunately, the assortment is just a huge assortment, so there should be no choice with a choice of work.
Copper lubricant for brake cylinders and calipers
It is the most common and popular among motorists. High temperatures are not afraid and is inexpensive, it makes it so popular. Most often used for processing disks, brake pads, as well as for brackets and other brake system elements. It is worth noting what is applied to the opposite side of the product. If these are pads, then their front side should not be covered with any lubricant, it concerns the disks.
The process of applying paste is also extremely simple. For this, the surface being processed is cleaned from dirt and corrosion. Further, the brush is applied with a tassel and is evenly distributed over the entire surface. It is worth noting that it is sold and in the cans, in this case it needs to be sprayed, after reading the instructions for use.
Basic base for high-temperature lubrication
On the shelves of auto shops are currently just a huge selection. But if you figure it out, then there are only 3 extensive groups:
- mineral base;
- synthetic basis;
- mineral or synthetic basis with a small amount of metals.
If you understand what a lubricant should be used for the brake cylinder, it is best suited that is made on a synthetic basis. This is due to the fact that it is neutral to rubber and plastic products. Consequently, anthers do not eat and is ideal for processing brake piston or guide caliper. The base used gives a number of advantages, such as low evaporation, high temperature threshold, insoluability in water and other liquids. In general, an excellent choice is true, not always budget.
It is much cheaper than lubricant for pistons of mineral brake cylinders. But it is still better suitable for guides, since it is able to withstand temperatures from -45 to +180 degrees Celsius.
Lubrication with the addition of ceramic particles
Relatively new development, which has already managed to gain popularity. It is expensive, but the stated benefits are very encouraging. Raising performance characteristics Lubricants are achieved due to the presence of a small fraction in ceramics. At the moment it is one of the best methods for protecting brake cylinders and their landing places from corrosion. In addition, the processed nodes exclude the possibility of sharp temperature drops, the formation of dirt and dust on the surface.
Despite the high cost of such products, it is extremely popular among motorists. It can be used as a lubricant that is less loaded compared to the front. Among the most popular high quality producers can boast a firm "Liquima Moli". Well, now we go further and consider some more extremely important points.
How is the maintenance of the brake system?
Often, the complex lubricant is recommended when replacing brake pads or disks. There is nothing difficult here. First inspect the condition of the guides. We clean your fingers and planting places from rust and process a certain amount of lubrication. Copper, graphite, etc., is suitable for piston, then the lubricant is needed to reduce friction and corrosion protection. The surface of the part is desirable to handle a small amount of ceramic lubrication. It effectively protect the surface from rust.
An extremely important detail is that it is worth regularly checking the state of the anther. If he is torn, no lubricant will help. First you need to replace and then lay the lubricant material. In addition, it should not be too much, as it will begin to squeeze through anthers and cuffs, which is not good.
Many experts recommend not to save on lubricants for calipers and buy only proven products. For instance, optimal lubricant For pistons of brake cylinders on silicone basis. It is completely safe for anthers and at the same time is high-temperature. Consequently, it works efficiently both in the winter and summer.
Car service specialists often do not fulfill their direct duties. For example, the calipers and guides must be cleaned when replacing the pads, but no one does. Therefore, it is better to do it yourself, especially since there is nothing complicated and even a beginner will cope. You should not neglect the maintenance of the brake system, but also to look there every 500 kilometers of the mileage also does not make sense. Inspect everything during the replacement of brake pads.
What lubricant is better to take?
It is advisable to use different types Lubricants depending on the work being processed. For example, the guide caliper is perfectly suitable for it is inexpensive and withstands high temperatures. Protects metal products from corrosion and prevents stripping. One of the most accessible options is TRW products.
The optimal lubricant for the pistons of brake cylinders should be on silicone or ceramic basis. Best manufacturer In this regard - FEBI. Cheap and angry. But the anti-graded Liqui Moly is not recommended for bookmarking the piston boot, as it can cause the destruction of the rubber seal.
The anti-graded paste is great for processing the brake pad plate and holding a bracket. Usually it ends with it. Remember that the lubricant of the brake cylinder cylinder should not be performed with pasta that corrupt rubber seals. This can lead to the complete destruction of the piston and the caliper.
Let's summarize
As you can see, there is nothing complicated in the maintenance of the car brake system. But at the same time it is extremely important to regularly lubricate all elements of the caliper that each time they work at high temperatures. Pay attention to the dust of the guide fingers. They are also subjected to wear, resulting in a rather unpleasant knock on irregularities. It happens because the finger freely hangs into landing place And it is not retained by plastic sleeve.
As for lubricants, now they are simply a huge amount. Any paste for lubricating brake cylinders, if it is designed for this, suitable for use. It is not recommended to lubricate the parts of the brake system by simple motor Oil or solidol, etc., all this will not lead to anything good.
Many of the brake system details with due service are capable of serving 200-300 thousand kilometers and more, it concerns calipers, guides, pistons, etc. Pads and wheels are more consumable, but it is also advisable to watch them too much. All this will allow you to feel more confident to feel behind the wheel and to know exactly that the brakes will not let it down, because everything is lubricated and checked there. Often, the problem is found precisely with the jamming of the guides and the tight stroke of the brake cylinder, which occurs in 90% of cases due to the insufficient amount of lubrication. If, with each replacement of the pad, lubricant for anthers of brake cylinders will be used, then you will not know the problems with the braking system of the car.
IN vehicle It is necessary to properly function all nodes and parts, however, at the same time, it should be taken into account that the brake system is one of the main. In the event of a motor breakdown or other important nodes, the car simply will not be able to move from the place, but the output of the brakes is in order to lead to very sad results. It is about this that every driver must constantly care for such important elements Vehicle and regularly carry out prevention, which is not a complex process and is made independently. I propose to consider what characteristics should take into account when choosing a braking lubricant and what lubricant is the most suitable for calipers. Only when using high-quality materials, you can guarantee reliable operation and mounting brake pads.
Brake caliper is one of the most important components of the brake system. It is from him that safety directly depends during the movement, as well as the life of passengers and the driver itself.
As a result of strong friction, the temperature of disc brakes is able to reach 500 degrees Celsius. If the vehicle is located in an aggressive environment, for example, when driving under the mountain, the details of the caliper are also impact. For this reason, only high-quality lubricants must be applied for guide calipers.
Lubrication for guide caliper, which gives brake lubrication
It's no secret that the brake system consists of pads, disk and calipers. Over time, the pads have the ability to wear, resulting in them to be changed. In addition, this node is also influenced by many other factors, such as: negative weather conditions, extreme ride or salt, which is sprinkled with garbage coatings.
However, the replacement of the pad is not able to solve all the problems. That the guide caliper functioned in the correct way, they need high-quality lubricant, which will fully provide trouble-free ride of the vehicle.
Technical characteristics of lubricants
Material manufacturers for lubricants are focused on certain conditions in which a particular node will work daily.
When taking into account a variety of parameters, in particular - the quality of the brake fluid, operation of cars under different weather conditions or too high temperature during brake pads, lubrication for brake caliper Needed with special characteristics:
1. Restable to the impact of various chemical compounds and to any water types - rain, fog, snow.
2. The lubricant must be high-temperature, that is, its operating temperature should be from 150 degrees Celsius and, if necessary, above.
3. It must be wake-up with elastomeric seals and plastic elements.
4. At high temperatures, the lubricant should remain as viscous to prevent its leakage.
Based on the parameters described above, and the lubricant should be selected for the brake calipers of your vehicle.
Copper brake lubricant
For brackets, anti-graded plates and metal coating pads, and to be more accurate, then for them back sideUse high-temperature and contamaged pasta. Such a group can be attributed copper lubricants With a powder of graphite and copper, with non-metallic filler, complex, that is, with different components and with Molybdenum disulfide.
Copper paste can provide protection and lubrication of components that are all the time under load, for example, fastening the parts of the suspension, the brake and intake system. In addition, they use copper paste and for lubricating spark plugs, as it is a resistant to high temperatures and they do not have the ability to influence it. Due to this, the paste is also used to lubricate compounds in the exhaust system.
To lubricate the desired element of copper paste, you should first clean it from corrosion. After that, we apply a paste with a brush or brush and distribute uniformly throughout the coating. The whole process takes only a few minutes.
Due to the wide temperature range in which the copper paste can be used, it is used in the energy, oil industry and in many diverse spheres.
In the vehicle there is another node in which you can use copper lubricant. When boiling or face the manual brake, the wheels are not capable of spinning. This can happen after visiting the car wash in winter time years or after a long standing of the car on the handbrake. In this case, the paste must be applied to the cables of the handbrake and the rear pads, which will bring the chances to zero to the fact that the handbrake does not want to move away.
High temperature lubricant
These pastes are used for pistons, sleeves, piston edges, and so on, however, they cannot be used with silicone components.
Universal lubricant
Universal lubricants are used for all moving caliper elements, including elastomeric and plastic.
Best manufacturers and best lubricant for caliper
If you are interested in finding out that paste for calipers is the most efficient and high-quality, I propose to revise the products of the manufacturers of narrow specialization:
1. "Huskey341" from the manufacturer Husk-ITT Corp.
2. Kluber Lubricarion Munchen k from the manufacturer "Kluber".
4. "Molykote".
5. "Liquima Moth" is high-temperature and one of the most effective.
High temperature:
1.ate Plastilube.
Universal:
1. "MS 1600".
2. "Molykote" AS-880N GREASE.
3. "Slipkote" Disc Brake Caliper Grease.
For example, among the CIS countries, the Berdyan Plant "AMSOLOL" can be noted, which is located in Ukraine, however, it is very difficult to find their products in retail.
Clean and lubricate the caliper is necessary during each replacement of the pads. To do this, you need to clean all the accumulated dust and dirt. Then, you need to lubricate the guide pads, the guide fingers and their anthers inside. Whatever the caliper would hang on the hose, it is advisable to hang it on a wire. In addition, it is very good to clean it, whatever rust marks left anywhere. Next, the ends of the pads should be treated with a file and install all the details into place. To close the caliper, the brake cylinder needs to be deepened. Do not cost forget about the level of brake fluid. After assembly, pump brakes. After lubricating the guides, it is possible to accumulate a large amount of dirt, although it depends on the weather conditions.
There are lubricants for calipers who are not able to collect dust and dirt, such as LiquimolicUfperpaste.
It is worth saying that you do not need to save on the lubricant, since low-quality pastes are capable of crystallize and stick. It is unlikely, inexpensive lubricants from dubious producers will be able to guarantee the optimal, long-term and uninterrupted operation of the brake system. You must choose a lubricant for your car, respectively with the classification by groups.
Manufacturers of cars and motorcycles advise the use of silicone and high-temperature lubricants, as they are the best and guarantee trouble-free operation of the brake system, reliably protecting it from aggressive impacts. ambient - dirt, temperature drops, moisture and dust. Therefore, when choosing a lubricant, you need to pay attention to those materials that meet the requirements listed above and have a manufacturer's quality certificate.
The end itself, I would like to say about fairly common graphite lubricants, the so-called "graphs", which are strictly forbidden to use to lubricate brake calipers. They keep relatively low temperatures and can burn or flush.
Konstantin Dubarev - owner car Kia. Cerato talks about how to eliminate the brake creaking. New branded pads set on Kia Cerato 2006 released, creaked. Konstantin used lubricant, after which the creak instantly disappeared.
In August 2012 It's time to change the front brake discs and pads on my Kia Cerato. 2006 release. Usually, I am not inclined to save on repair, especially if it comes to the reliability of the brake system, so I purchased an original kit for spare parts. After installing and running the brake pads (700-1000 km), I began to notice that the pads begin to creak when braking. And if at first it was about a periodic viper, then somewhere in a couple of weeks the pads were squeak at each braking. In general, I understood that the creak and braking efficiency are little related, but it is very unpleasant to hear.
After having studied the topics of the fight against creak, I stopped using universal lubricants for brake systems. The use of special anti-graded plates I immediately shallow, as they need to be selected under the blocks and the caliper, which means to go to the store again, order, wait, in general, spend time. I also abandoned the use of highly specialized lubricants for brake systems (like copper pastes or lubricants only for guides) for almost the same reason: if you need to serve the caliper, for example, with the next shift of the pads, I will need to provide the mechanics at least two lubricants. Why, if you can do with one tube. So, after applying universal lubrication on the non-working surface of the pads, contacting the caliper when braking, the creaking instantly stopped.
The most interesting thing is that the lubricant was useful to me literally in a week. Making smooth braking on one of the urban intersections, in the driver's mirror of the rear view, I saw the smoke that it was to see how it seemed to me, from the rear wheel arch.
After a few seconds, this smoke leaked into the salon, and I felt the caustic, irritable for the eyes, nose and blood stroke. After that, the car was still drowned, however, during acceleration, and when braking, the car behaved quite sluggish, as if something would interfere with her. In addition, switching gear (automatic transmission) has become less smooth. In the evening of the same day, I naturally turned to my mechanics. He diagnosed the encoding of the rear caliper. In fact, the brake piston stopped working, since the guide caliper climbs. And they exactly "thanks" to the fact that in due time were not properly processed.
Of course, the caliper, I had to be replaced, and this time the universal lubricant was useful for lubricating the guides to no longer scattered.
Expert opinion. Change the pads correctly.
When replacing the pad it is very important to pay attention to the lubrication of all parts of the caliper: guides, non-working surface of the pads, piston, anthers.
Lubazan guide caliper
universal lubricant on synthetic basis
It may take more time than just the usual replacement procedure of the pads, but paying attention to every detail, we ensure our safety and long life of the mechanisms. Disc brakes work in the most severe conditions of high temperatures, which in the friction pair of the disc-block can reach + 500 ° C + 600 ° C. When replacing the pads are used different lubricantsAnd the work of all components of the caliper largely depends on their choice.
Random lubricants
The aerosols are very convenient in applying, but they are not combined with the rubber elements of the caliper, in connection with which their deformation and loss of tightness occurs.
The boot increased by 3 times and lost hermeticity after the use of graphite lubricant.
The use of copper-containing aerosols gives a similar effect.
Traditional lithium or graphite lubricants have an oil base and are therefore not compatible with rubber anthers. These lubricants have a low temperature range and quickly burn out. Such lubricants are easy to determine by operating temperature until 200ks.
The so-called "Medickens" (copper lubricants) do not always withstand high temperatures and burn out on guides, provoking corrosion.
Specialized lubricants for different caliper nodes do not imply multipurpose use.
How to choose a lubricant for calipers
When choosing lubrication, it is very important to pay attention to the main characteristics:
- High temperature range
- Immissibility with brake fluids,
- Synthetic base
- Versatility of application
- Content with rubber parts.
Now that we know the reason and ways to eliminate it - act! When you change the pads, lubricate the guides, piston and non-working surface of the pad, while using universal high-quality lubricant for calipers.
