There are certain periods of the periodicity of the replacement of the brake fluid Renault fluence, strictly indicated by the manufacturer. Menuing liquid should be one and a half - two years. In addition, there are special testers to verify the state of the brake fluid. The main operating characteristics of the brake fluid is its boiling point. If it is not lower than 175 degrees and the service life does not end, it is not necessary to change it. If the temperature in the range of 165-175 is a border state, soon it will be necessary to replace. If below 165 - urgently change in any case.

To replace Renault Fluence brake fluid, we advise you to contact our car services of St. Petersburg. Experts will make everything competently, quickly, neatly and inexpensive. To pump the brake system of cars with the ABS system, you may need special equipment and connecting the computer.

The cost of replacing the brake fluid:

Type of work:Price
Replacing the brake fluidfrom 800 rubles.
Replacing brake fluid through equipmentfrom 1200 rubles.

Where the brake fluid is changed Reno Flyuens in St. Petersburg:

With a self-replacement of the brake fluid, Renault fluuens, in no case should the liquid should be addressed, especially if you do not know exactly what was flooded. Brake fluid must be changed completely. In the remaining old brake fluid there may be a precipitate and excessive moisture.

Important. During the engine operation, its temperature of the brake fluid rises to 150 degrees. If the working temperature of the liquid is equal to the boiling point, it will boil and the brake lock will occur. In addition, if the brake fluid is clogged, the brakes can jam. Consequences can imagine themselves.

When to replace the brake fluid:
- expired the life of the brake fluid;
- test results showed that the brake fluid must be replaced;
- Pedal slightly sends under the foot

Important

1. Brake fluid is necessary to transmit brake force.

2. Today, 4 varieties of liquids are sold, each of which is characterized by the basis and additives.

3. Specific signs of degradation (production) of the brake fluid is not available, which makes it important timely preventive service.

4. Brake fluid should only vary on the recommended manufacturer, in the conditions of an authorized service center.

Why do you need brake fluid

In modern cars, RENAULT FLUENCE is implemented a hydraulic brake system, where the brake fluid is used to transmit efforts from the brake pedal to the brake pads. Until 1928, only a mechanical drive was used in the automotive industry, which did not differ in efficiency. All modern cars are already equipped with a hydraulic drive, which informs the necessary effort on the brake pads.

In some machines, the liquid is also used in brakes, and in the clutch drive, if the car is equipped with a mechanical gearbox. In this case, the tank through which the liquid is refilled is used immediately in both systems. But the essence of the brake fluid remains one - the transfer of effort from the pedal to the appropriate mechanism. And the timely replacement of the brake fluid Car Renault Fluence remains an important point of the vehicle.

To understand the process of working fluid, it is worth considering the principle of operation of the brake system. It includes:

  • the filling tank - the system is refilled through it;
  • level sensor - controls the presence of brake fluid, when triggered, the movement on the machine is prohibited;
  • pedal and its drive;
  • the main brake cylinder - the drive is reported to it, removed from the pedal;
  • hoses and sockets of systems in which the brake fluid moves transmitting force from the GTC to the brake cylinders of the wheels;
  • brake cylinders of wheels, driven by the pressure of the working fluid, and include braking with the help of pads.

If you remove the brake fluid from this system, then pass the force from the pedal to the pads will be impossible - the mechanical drive is simply not effective, since to stop the car RENAULT FLUENCE weighing more tons of effort will not be enough.

Brake fluid must have a number of properties:

  • do not freeze at temperatures up to -60 ° C;
  • have a boiling point of 200 ° C;
  • viscosity of at least 1.5 mm2 / s at T \u003d 100 ° C, but not more than 1800 mm2 / s at t \u003d -40 ° C;
  • density stability, regardless of conditions and intensity of operation;
  • do not exert the devastating effect on rubber and rubber-like system materials;
  • lubricate the working volume of cylinders.

Given that the temperature range of operation of the brake system varies from -60 ° C (extreme north, plague) at a cold start and up to +150 ° C (with a private braking from 60 km / h to a complete stop), ordinary oils are not suitable. In addition, water should be missing in the hydraulics - the main cause of the braking fluid Renault Fluence.


Generation of brake fluid

The classification was based on the standards developed by the US Department of Transport. Accordingly, the name of each type (generation) uses Abbreviation Dot - Dept. Of Transportation. The main difference between each of them is the basis used for development. Its percentage is at least 92%, the remaining 8% are special additives.

1. DOT 3 - Mineral base, which is both "plus", and "minus". Dot 3 does not have a devastating effect on the metal and rubber parts of the system, the cylinders are well lubricated and eliminates the risk of "zaksania", the occurrence of corrosion. It becomes too viscous at a temperature of less -20 ° C, quickly absorbs moisture and degrades literally in 1-1.5 years. Used on old Renault Fluence with drum (or disk + drum) brakes.

2. Dot 4 is a synthetic base presented (mainly) a mixture of ether and polyglycol. Wrong enough, it, despite the rather "honorable" age, is used in the working systems of most modern Renault Fluence cars. Of the advantages of DOT 4, it is worth nameing the stability of properties in a very wide range of temperatures. The maintenance of the brake system is produced once 2-4 years, depending on the characteristics of the car itself.

3. DOT 5.1 - Mixed base is some kind of DOT 4, but it is characterized by greater hygroscopicity at a lesser viscosity and a higher boiling point. Usually, used in sports cars.

4. DOT 5 - synthetic base based on silicone. Stable properties in a very wide temperature range, ideal for high-loaded systems (sports cars, SUVs and heavy luxe class sedans). Not hygroscopic. Not suitable for systems that have rubber or rubber-like elements.

Liquid hygroscopicity is still a "weak place" of any braking system. Automakers apply a large number of engineering solutions to limit contact with moisture, but it is impossible to do a completely sealed system - it will negatively affect its performance.

The presence of water in Dot 3 and 4 reduces its properties, makes them less stable. In addition, water particles lead to the rapid formation of corrosion inside the system, and can cause "watering" of working cylinders, which will make braking less effective, or not possible.

Characteristic signs of brake fluid degradation

Specific features, according to which the ordinary car owner could determine the degradation of the brake fluid Renault Fluence, was not detected. Under normal conditions, even a large degree of work out is practically no manifest. However, it becomes fatal with intensive load on the brakes - descent on serpentine, emergency braking, off-road movement. In a word, in any situation, when the load on the brake pedal is large.

Quickly detects the need to replace the brake fluid, with the prophylactic pumping of the brakes. For this, a diagnostic strip is used, changing its color depending on the presence of moisture in the analyzed substance.

The degrading liquid paralyzes the operation of the system, and here it is possible 2 options - either cylinders work on disclosure (spontaneous braking), or the car will stop responding to the press of the brake pedal. In any case, the situation will be dangerous for road participants.

But the owner's wrapping should not be a common behavior of the pedal:

  • unexpected failure, especially with emergency braking RENAULT FLUENCE;
  • the effect of "pumping" when the pedal with each pressing becomes more elastic, and its move is shorter;
  • tight course of pedals in the frost.

These are not direct signs of liquid degradation, and are characteristic of other problems in the system. And, nevertheless, contact a hundred and at least to replace the brake fluid.



How often brake fluid changes

The frequency of fluid replacement is specified in the Renault Fluence car service book. But the data given in the car documentation was obtained in the laboratory and in fact they relate to real life. The fluid resource of the brake system does not depend on the intensity of use, but if the car costs without any movement of any long time (3-4 months or more), it is necessary to check the brakes.

If you take averaged indicators:

  • for dot 3 - annually, in front of the winter period of operation, or after the cutting of the car, not operated in the cold season;
  • for Dot 4 - 1 time in 2 years, when preparing a car by winter. Liquid varies after the Renault Fluence car is cut;
  • for DOT 5.1 - annually, regardless of the operation of the car;
  • for Dot 5 - 1 time in 4-5 years. As a rule, the replacement during the decons is not required, but the level control and pumping of the brakes is required.

An equally important issue is considered to be compatible with mixing liquids. Manufacturers strongly recommend mixing fluid, and automotiflowers remove the Renault Fluence cars with warranty if the fact is detected by refueling not suitable liquid, or mix them.

As for compatibility, in emergency cases DOT 3, 4, 5.1 is allowed to mix if you need to get to the repairs. The silicone base DOT 5 eliminates the plot into the mineral or synthetic hydraulic fluid system.

The replacement of the fluid is needed if the Renault Flunce car is purchased in the second-hand state.


Rules for replacing the brake fluid

Drivers are confident that there is nothing complicated in the replacement of the brake fluid, and this procedure is actually carried out on their own. But even the slightest error will turn the tragedy when the brake fails. After all, this procedure includes:

  • full pumping of the working fluid;
  • purge of hoses and pipes, cylinders;
  • refueling system and her pumping.

Maintaining the required brake fluid level It is necessary for the proper operation of the brake system of the car. How much it will always be necessary can be found in the service book, but often the car owners are not used to to look into it, but to act an experienced way or seek an answer on the Internet. Such users will try to help deal with the question how many brake fluid need For replacement and what it is worth pouring.

- Working fluid of the brake system, with its help the effort generated in the main brake cylinder to the wheeled pairs occurs.

If the level of the brake fluid is below the minimum mark (by the way will notify the corresponding icon on the instrument panel - a red circle with the waves inside), then it is necessary to add. It will also not hurt to check the braking system, since the decrease in the level of the TJ may indicate its malfunction or wear. As a rule, in the brake system of the passenger car, it contains from 0.55 to 1.0 liters "TORROSUhi". And its specification can very often be indicated on the housing of the expansion barrel or its lid.

Do not forget during check paying attention to the color of the liquid. New TJ transparent with a yellowish tint. In the course of operation, it changes its color and become dark, it is mainly due to the accumulation of different impurities. If the liquid has darkened, it may mean that it is necessary to have a complete replacement and a simple plot here can not do. Specialists are recommended to replace the brake fluid approximately every 2-3 yearsThis is precisely such a gap is optimal in accordance with hygroscopicity and exposure to temperature loads. For the proper functioning of the brake mechanisms, the liquid must have a number of properties, as well as to meet a specific standard.

Old and new brake fluid

Type and TJ properties

Any braking fluid has 93-98% of the main composition and from 2 to 7% of additives, which, in fact, are the key components for making the stated characteristics. In general, if you look so, then the properties of the brake fluid depend on the combination of its components. Depending on the composition of the foundation, the TW is divided into 3 groups.

Types of brake fluids:

  1. Mineral (LHM mineral oil). They consist of alcohol and castor oil.
  2. Glycolic. Developed on the basis of polyglycol and their esters.
  3. Silicone. Made based on silvero-organic polymer products.

In independence, on the type and composition, all brake fluids are distributed into two classifications.

TJ Classification:

  1. By viscosity.
  2. By boiling point:
  • for the "dry" fluid (without water);
  • "Wet", which contains water 3.5%.

If the boiling point has exceeded the permissible standard, that is, the risk of the formation of a steam plug in the system (as a result of the evaporation of moisture), which is fraught with a breakdown and failure of the brake pedal.

Brake fluids standards

In practice, yes, and in most cases, it is customary to use the American FMVSS Quality Standard (Federal Motor Vehicle Safety Standard), which was developed by the US Department of Transport (Department of Transporation, and short DOT). So, often, in modern cars, it is applied either DOT 4 on a glycol-based basis, or DOT 5.1 (consists of glycolic and silicone compounds). But in cars released more than 20 years ago, BSK or DOT 3 liquid can be used.

It is important to understand that the DOT 5 fluid is characterized by a chemical composition from others, so it should never be mixed with DOT 3 or DOT 4, as well as used in systems intended for DOT 3 or DOT 4 liquids so as not to damage the brakes.

The standard dot clearly describes such characteristics as:

Dot 4 brake fluid (relevant standards: SAE J1703 & J1704, FMVSS 116, JIS K2233, ISO 4925)

  • degree of viscosity;
  • boiling temperature;
  • chemical inertness to materials (for example, rubber);
  • corrosion resistance;
  • constancy of properties within operating temperatures;
  • the possibility of lubricating elements working in contact;
  • the level of absorption of moisture from the surrounding atmosphere.

In accordance with the standard FMVSS №116 The brake fluid variants are divided into five classes, each of which is designed for a certain type of work and even the type of brake mechanisms - disk or drums.

But do not think that these are uniform existing standards, because in Europe will be - SAE (Society of Automotive Engineers) J1703 / 1704., ISO (DIN) 4925 - International Organization for Standardization, in the Middle Kingdom, Japanese - JIS. JAPANESE INDUSTRIAL STANDARD) K2233.. But Russia and other countries of the CIS of the Unified Standard, which regulates the quality indicators of braking fluids, does not exist, so manufacturers work according to their specifications.

Application of brake fluids class DOT

Since in many cases all are focused on the American standard dot, consider in more detail all five classes:

  1. DOT 3. - Designed for low-spirited cars with drum and disk front brakes. The booster temperature is 220 ° C.
  2. DOT 4. - Fill in the brake system of high-speed cars in which disc brakes are installed on both axes. Boiling occurs at a temperature of 240 ° and 160 ° C.
  3. DOT 4+, DOT 4 Super - Modifications DOT 4, their boiling point is 260 ° C and 180 ° C.
  4. DOT 5. - Silicone TJ, which cannot be poured into a car with an ABS system, because it does not absorb moisture, but allows it to be collected in one place. Due to the fact that the boiling point is 280 ° C and 180 ° C (for "dry" and "wet" liquids) with a low viscosity, as a rule, applies only in racing cars.
  5. DOT 5.1. - For rapid cars, whose brakes are often overloaded. It is more high-tech and testicular than dot 4, but still absorbs moisture. It is often recommended for use in systems with ABS and ESP. Operating temperature 270 ° C and 180 ° C.

With regard to the life of the liquids of various classes, it should be noted here that the brake fluids of the class DOT 3. have a service life about 1-2 years, in turn Dot 4 - 2-3 years, and dot 5.1 need to change once in 3-4 years. DOT 5. You can operate before 5 years.

Liquid volume in the brake system

Mostly brake system accommodates from 0.55 to 1.0 Litra fluid, it depends on when in the car ABS and the size of the machine. The period of replacement of the brake fluid in most cars is 2-3 years use or 40-60 thousand run. To determine a more specific gap, you need to look at a certain standard of fluid and driving features. For example, in sports cars, the TJ is changing every 5-10 thousand.

But since the question of the right volume of brake fluid in the system and its standard is set only owners of ordinary cars, and not a premium or business class, we will give specific examples for the machines in the CIS countries.

How many brake fluid in the VAZ system

As you can see in the TA Table Table, in cars VAZ Pour the brake standard DOT-4., but its number in the brake system can be from 550 ml In the classics (VAZ 2107), up to 1.0 liters in more modern domestic cars, such as VAZ 2110. or Kalina. But if you make a replacement with flushing, it is worth getting 1.5 liters, and since there is no such package, you will have to buy two bottles of liter.

At the same time, remember that in open state the shelf life of the brake fluid is limited in two years.

What brake fluid is better

The brake fluid has sufficient influence not only on the state of the braking system, but also on its effectiveness. The most important criterion when choosing a suitable TJ will comply with the necessary properties and requirements. But as a rule, on the packages of different manufacturers, everything is very beautifully written, but whether the liquid corresponds to the stated four basic requirements, such as: a large boiling point, minimal corrosion activity, lubricating properties and stable viscosity. This can be learn only by experienced and according to user reviews.

Expertcen's employees with the best brake fluids of foreign production are such as: Castrol React Dot4. (price 450 rubles.), Motul Dot 5.1. - It will cost at least 600 rubles, Liqui Moly BremsenFlussigkeit Dot4 - 300 rubles. In the list of decent brake fluids of the domestic manufacturer, you can allocate: ROS DOT-4 - 180 rubles, SINTEC SUPER DOT-4 - 100 rubles.

But in order not to endanger yourself and other road users also pay attention to those brands whose quality is not at the highest level. Among such dubious buildings there are: LUXE DOT-4 ("Delphin Industry"), " SINTEC DOT-4"(TOV" TLC-Khimreakiv ") and" Alaska dot-4"(LLC" TEKRO "), it is they who do not meet the requirements of the DOT-4 class according to the boiling point. In addition, there is still a liquid "Alaska Dot-4" there is a viscosity deviation at -40 ° C. In turn, such liquids as: " Oilright Dot-4"(LLC" Tektron ") and LUX DOT-4 (CJSC "Delphin Industry") have a sufficiently low boiling point in a liquid that contains moisture, such parameters do not even correspond to even the class DOT 3. Also obstacles to the requirements of DOT 4 by viscosity at -40 ° C, in liquids: PP "Lumo" (Ukraine) and Belhim Dot 4. (Belkhimgroup, Belarus), which is 15-25% above the norm.

When choosing a brake fluid, it is possible to carry out analogies for a long time, to be tamed with reviews, consider the list of characteristics, but with all this you need to remember that even the brake fluid that has the best indicators among others, there is a deadline for use and it is necessary to replace it declared regulations from the manufacturer because your security depends on the state of your car.

Summing up, let's say that only the brake fluid is needed, which the automaker recommends. Buying a tormozuhu for your car, be alert, necessarily pay attention to the specificationwhich is necessary for the car. If we talk about the necessary quantity to replace the brake fluid, then, as a rule, in the domestic production machines, it is required from 0.5 to 1 liter, while the volume of the TZH in the braking system of foreign cars is from 1-1.5 liters. Therefore, when replacing and pumping brakes, consider this fact and always follow its level in the expansion tank.
