How to pump the brakes in the right-hand car. Pumping brake system: step-by-step instruction. Pumping brake system with ABS

Air in the brake system is a potential security threat. It may be there to form from the vapor of boiling brake fluid (due to the large amount of condensate), leaks, damage to parts brake system or in the process of replacing hydraulic components. Therefore, before starting the brake pumping, it is necessary to check whether the system is sealed - the locations of the connections of the elements.

In addition, it is necessary to remember how the brake fluid has been filled. It must be changed every two years and in no case can you mix different types liquids. For example, if the "TORROSUKH" type DOT-3 is filled, then do not use DOT-4 or DOT-5 - this can lead to "dissolving" seals in brake cylinders and places of connection of the system components.

Pumping brakes only at first glance seems a challenge. However, she is quite responsible. It depends on the correctness of the actions - will the brakes at the most inopportune moment be submitted. If you are not sure of your skills, it is better to ask for help in the service, and spend your free time to meet with friends.

If you still decide, then stick to the basic rules, and then no problems should arise. First, during air booming in the tank there should always be brake fluid. Secondly, it is necessary to strict adherence to the correct sequence of actions.

Attention! In a car without ABS, the pumping must begin with the wheels of the most remote from the brake pump - usually rear right. Then go to the rear left, front right and end the front left. In machines with ABS, the procedure starts with the front wheels.

Thirdly, we must be careful with the running valves. If they are strongly pranged or dirty, then before unscrewed, clean the wire brush and process the liquid key type (WD-40). This will help easier to unscrew the valve. After opening the valve, the brake fluid should be drained until we see the absence of bubbles, and the liquid will become clean and transparent.

And one moment. For high-quality pumping of the brake system, two people are needed. Ask for help friend. Together, it is more effective, faster and, of course, more fun.

Pumping brake system withoutABS

Pumping scheme:

1. Brake cylinder or rear-right caliper.

2. Brake cylinder or rear left wheel caliper.

3. Far right wheel caliper.

4. Caliper front left wheel.

Attention! On cars with the distribution of brake efforts along the axes (in the commoner "sorcerer") during the rear brake pumping, it is necessary to move the lever (piston) of the sorcerer to simulate the full load of the machine. This will ensure the maximum throughput of the brake line and simplifies the brake pumping.

Sequencing:

1. Remove the cap with exhaust valve Ventilation of the wheel brake cylinder, clean the valve and put on the pure transparent hose. Another end of the hose insert into the container with a brake fluid filled to half.

2. Ask your assistant to push the brake pedal until the pressure is created in the pressure system. The sign will be the growing resistance of the brake pedal.

3. To create pressure, you must completely press and hold the brake pedal.

4. Loosen the air outlet valve on the half turn. Liquid flows into the container. The second end of the hose must be immersed in the liquid.

5. After a noticeable drop in the system in the system, tighten the vent valve.

6. Repeat the pumping operation with a pressed brake pedal.

7. Repeat pumping again until air bubbles disappear into the fluid in the hose.

8. Remove the hose from the exhaust valve and replace the protective cap.

9. Repeat the same actions for the brake cylinders of the other wheels.

Pumping brake system withABS

In cars equipped with ABS, the process is slightly different. If the fluid level in the tank drops too much during pumping, then the air can be hit in the brake system, which will be in the pump. In this case, you will not be able to continue pumping the system, and have to contact the service.

Front wheels:

2. Fill the brake system tank to the very edges.

3. Put the transparent hose on the air release valve of the right front wheel. The other end of the hose is lowered into a container with brake fluid.

4. Ask the assistant to push the brake pedal until the pressure appears in the system. Then, holding the brake pedal pressed, unscrew the valve. When the pedal resistance stops, close the valve.

5. Repeat this procedure several times until the fluid in the hose is without bubbles.

6. Close the valve and fill the tank brake fluid.

7. The second "wheel" pump exactly the same way.

Rear wheels:

1. Turn off the ignition and click on the brake for about 20 times to get rid of the ABS control pressure.

2. Click and release the brake pedal.

3. Turn on the ignition, put on the hose and open the airflow valve of the right brake cylinder. Close the valve as soon as air bubbles will stop appearing in the hose.

Attention! The ABS system pump should not work more than two minutes, otherwise it overheats. Thus, after every two minutes, it is necessary to make a ten-minute break for cooling the pump.

4. Turn off the ignition and prepare the left-wheel brake valve.

5. In the same way, pump the second "wheel".

6. Turn the ignition and wait until the ABS pump is turned off on your own.

7. Different in the brake tank liquid to the maximum.

Learn how to pump the brake system by car do it right. Step-by-step instructions "For young" car enthusiasts. Useful advice and answers to questions: how to detect air and how often change brake fluid in car.

To start a little theory. Pumping the brake system on the car is needed to get rid of the air, which over time is formed in it. There may also be other causes of air in the brake system, for example:

• when repairing the brake system itself (for example: or, any tuning and other intervention in the operation of the brakes);
• if the brake system is deployed in case of damage to oil tubes or hoses (they could be outraged and crackled);
• if you should immediately begin this procedure;
• with a large recession of the level of the brake fluid in the tank of the main brake cylinder for the MIN mark.

How to detect the resulting air in the brake system? This can all be noticed when braking (braking stroke will increase, not smooth stop) and when you press the pedal itself, an increased step will be detected and the softness of the press. In fact, this is a very important knot in the car - because the life of the passengers themselves and those who are outside of transport depends on its established work. So the well-established brake work should be in the first place.

How often do you need to change the brake fluid? The procedure for replacing this fluid should be carried out once every two or three years, depending on how often you are operating your car. If you drive very often, then by "doubles" 50-60 thousand kilometers - should also be replaced.

The procedure for pumping the brake system should learn to do it yourself - do it yourself, it is not really difficult. What for once again Contact the car service and pay money when you can do everything yourself.

1. The whole procedure should be carried out with an assistant, its task will be to press on the brake pedal.
2. Take the brake fluid only to the brand, which was filled into the system. If you do not know what was flooded, then see what the manufacturer of your car recommends. And when pumping should always be in a liquid tank at least 1/2 level, or not lower than the MIN mark.
3. Before you begin to work first, inspect the entire brake system - all tubes and devices to learn or does not flow where the liquid. If everything is fine, then you can proceed to pumping.
4. If there is an ABS on the car, then it should be turned off. ABS is disconnected by removing the corresponding 40 amp-melting insert in the rotary / fuses.

The sequence of pumping brake mechanisms is carried out in a strictly specified manner:

• rear right;
• front left;
• rear left;
• front right.

The whole procedure was carried out by car VAZ 2110. You can apply it to any other brand of the machine. But first should be familiar with the technical documentation of the car and find out the possible some subtleties of pumping the brakes if they are.

The phased process of pumping the brake system:

1. Check the level of the brake fluid in the tank and, if necessary, add it to the Max.

2. When the rear wheels are posted, you must first unlock the pressure regulator of the rear brake mechanisms. To do this, it is enough to insert between the plate and the piston of the usual score. At the end of the work, remove the scores.

3. On each wheel (brake mechanism) you need to clean the air output valve from the mud.

4. From air outlet valve, it is necessary to remove the protective cap and put the hose on it, the other end of the hose is lowered into the tank with a bit filled with brake fluid (you can in a bottle any, preferably transparent). The hose must be immersed in liquid!

5. Now the assistant must press the brake pedal from about 3 to 5 times with an interval of 1-2 seconds. In the last press you need to fix the brake pedal in the pressed position and keep it up.

6. Now you need a little (per 1/2-3 / 4) unscrew the air valve. In the overlooking the brake fluid hose, air bubbles will be seen. How to flow fluid will stop tighten the air output valve. Now the brake pedal can be released.

7. This procedure should be repeated from about four to six times until air disappears in the flowing fluid. But after each procedure, you need to check the amount of brake fluid in the main tank, if necessary, tosses it, it should not fall below the mark "min".

8. How the air will end, remove the hose, wipe the valve fitting and put the protective cap on it. In such a sequence of actions, the remaining three wheels (brake mechanisms) should be pumped.

1. First, we are looking for and removing in the fuse box that the fuse that is responsible for the operation of the anti-lock system.
2. Next, raise the jack and remove one front wheeland we are looking for a fitting of the working brake cylinder (RTC).
3. After that, on the fitting we put on the hose (from the hydraulic level, for example).
   
   
4. Open the fitting on one turn.
   
5. One presses the brake pedal until it stops and holds it in this position.
   
6. Now turn the ignition key to turn on the hydraulic pump (the ABS indicator is lit on the instrument panel).
   
7. The second person looks at how the air is removed through the hose and, after removing the air, spins the fitting.
   
8. The brake pedal is released only after twisting the fitting.
9. Now, how to find out that all the air came out of the ABS? It shows the ABS icon on dashboardif it is ground after removing the air and twisting the fitting, then all the air came out.
   

Proper sequence of pumping ABS system

There is a special order for the proper pumping of the brake system with the anti-lock system: the right front wheel, then the rear, then the rear right, and, then the rear left wheel. If, in the process of such works, the TJ left the system, it is necessary to fill the system new liquid. And for this you need to know which fluids can be mixed and how much brake fluid is needed for replacement.

Sequence of operation for the front wheels:

1. Turn off the ignition (position of the key "0").
2. Remove terminals with brake fluid barrel.
3. We take a bottle with a small amount of brake fluid and hose. One end of the hose is lowered into the liquid, the second we put on the fitting and open the fitting with a horn key. It is advisable to use a transparent hydroeer hose to be seen: air bubbles go or not.
4. Press the brake pedal and hold in this position.
5. The second person (the wheel) looks, whether the air went out, and, after the air bubbles ceased to go out, he overlaps the fitting with the key.

How to pump rear wheels with ABS:

The order of action differs in pumping the rear wheels. After the front wheels, the rear right wheel should be pumped in such a sequence:

1. We also wear a hose into a bottle with liquid and in the caliper fitting.
2. Squeeze the brake pedal to the end.
3. Turn the ignition key to the "2" position.
4. Hold the brake pedal while the hydraulic pump completely will not fade air bubbles.
5. Close the fitting and let go of the brake.

For efficient pumping, while working with the brake system of the rear left wheel, the procedure should be corrected. Namely:

1. As in other cases, we put on the hose, turn off the caliper fitting by 1 turn. When pumping with rear left wheels, the brake should not be squeezed immediately.
2. Turn the ignition key to start the hydraulic pump.
3. After the air outlet, click on the brake pedal half and close the fitting.
4. Next, let go of the brake and wait when the hydraulic pump turns off.
5. Turn off the ignition.
6. Connect the disconnected brake fluid tank connector (TZH).

In this video, it shows a way of pumping brakes with anti-lock on Audi A4 cars, Audi A6, Volkswagen Passat B5 and others.

Output

After carrying out repair and maintenance work with responsible components of the car, before the trip, first need to check the system's tightness and performance of the machine components.

ABS - Anti-Lock Braking System is a system against blocking wheels with a sharp braking. Due to the fact that the ABS does not allow the car to "swim" by the UZOM on the road, safety increases in emergency situations. The anti-lock system will work correctly if the system is not delivered.

Look a useful video. Tests show that even serviceable aBS system It turns off at the end of the brake path, so you still need to refine the foot.

The car "Toyota Corolla", despite the deserved confidence and authority among car owners, requires careful and careful relations. One of the main systems with which difficulties may occur during operation are brakes.

The car "Toyota Corolla", despite the deserved confidence and authority among car owners, requires careful and careful relations. One of the main systems with which difficulties may occur during operation are brakes. They must be pumped, but not all owners of this car brand can do it technically competently.

As new auto-community members and experienced drivers will always be easy and timely reminders that:

• all manipulations with brake fluid must be performed very carefully;
• do not interfere with the skin of a person, especially to take care of the eyes;
• prevent car-painted car
• keep brake fluid from contact with hot elements and fire - it is flammable;
• it is strictly forbidden to use the liquid again;
• only incompressible fluid will provide uninterrupted operation of the brakes, so it is impossible to allow its pollution or clogging.

Eliminate malfunctions to one person will be impossible because toyota Corolla brake pumping Requires "games in 4 hands", with their 4-fold repetition (of course, by the number of wheels).

Algorithm of all necessary actions:

1. Pumping begins with the longest brake system.
2. Install a car on a flat plateau. Move the motor, and put the gear lever to the rear position or 1 speed. Fix the wheels, lower the handbrake.
3. Pre-pour a working mixture similar to SAEJ 1703, VSS116DOT3.
4. Remove the main cylinder, be sure to roll out air from there (if it is empty or the fluid level reached a minimum).
5. Remove the brake tubes from the cylinder.
6. Press on the brake, and smoothly, without jerks, to hold it.
7. The outlet holes of the cylinder pinch with fingers, lowering the brake.
8. To learn this order of repair and repeat it 3-4 times.
9. Connect the tube to the brake caliper.
10. Press-squeeze the brake several times, weaken the bleeding fitting and release air. Lower the pedal.
11. Repeat the process until the fluid stops flowing (simultaneously with the appearance of air bubbles in it).

Manufacturers companies presented to people (instead of improving the art of the auto industry) the possibility of enjoying a comfortable and pleasant pastime. This is due to sensors, valves and electronic block Control to change in the brake pressure system. This "smart" ABS system has features of brake pumping:

1. It is necessary to view the previous paragraph, point number 3.
2. The end of the tube is to put on the rear stupip valve, another part of it is lowered into a clean capacity with a liquid.
3. Rotate the ignition key to the second position, press and hold the brake. The pump will turn on independently by lifting the pressure in the rear contour of the brake.
4. Loosen the valve so that the liquid began to go out. It is important at the same time not to let the brakes!
5. When air bubbles disappear, spin the valve, lower the brake, turn off the ignition.
6. Add the level of brake fluid to the top.

• first pumping the foreframes (you need to follow the "braking" regulations);
• pump with hydraulics include for one reception no more than 2 minutes;
• after 2 minutes of work, be sure to turn off the ignition and cool the pump for at least 10 minutes.

Pumping hydraulic system brakes

Brake liquid poisonous. Rinse the body part of the body with an abundant amount of cold running water, which hit the liquid, and immediately consult medical care if the liquid fell into the oral cavity or eye. Some types of brake fluid flammable and can ignite with hot components. Take appropriate fire safety measures. Brake fluid is aggressive to coloring and plastics - when it gets into such surfaces, immediately wash the liquid with an abundant amount of water. In addition, liquid is hygroscopic (absorbs air moisture) - the old liquid can be contaminated with water and is not suitable for use. When placing fluid to the system or replace it, use the recommended type of fluid, pouring it from just an open sealed container.

Models not equipped with ABS

general description

Proper functioning of the brake hydraulic system is possible only if its components are free from air. To remove air from the system, pump it.
During the pumping procedure, add only pure, fresh brake fluid specified in type specification. Never use liquid again.
If there are any doubts about the type of liquid, filled into the system, rinse the system with clean liquid and replace all seals.
If the main cylinder fell the level of brake fluid, find and eliminate the cause of leakage before you continue to work.
Park the car on a flat place (not under the slope), turn off the ignition and select the 1st transmission or reverse. Block the wheels and free your handbrake.
Make sure that all tubes and hoses are attached securely, the couplings are clamped, and pumping fittings are closed. Remove the dustproof caps and take the dirt from the bump fittings.
Remove the brake hydraulic reservoir cover and bring the fluid level to the "MAX" line. Put the lid and do not forget to keep the fluid level above the "min" line throughout the procedure, otherwise the air will again fall into the system.
There are a number of fixtures for pumping the brake system with one person. It is recommended to use one of these sets as they greatly simplify the work, and also reduce the risk of returning to the system of air and liquid out of it. If such a fixture is not available, apply the main method of pumping (for two people), described in detail below.
If the device is used, prepare the car as described above and follow the instructions of the kit manufacturer. The procedure can vary significantly depending on the type of fixture used, its main move is also described below.
Whatever method is used, follow the correct sequence of pumping.

Sequence pumping

If only one of the circuits were disconnected or removed (for example, a caliper or a braking cylinder), only this circuit needs in pumping.
If the entire system is subject to pumping, act in the following sequence:
a) Rear right brake mechanism.
b) Front left brake mechanism.
c) Rear left brake mechanism.
d) front right brake mechanism.

Pumping - the main method (for two people)

Order procedure

1. Prepare a pure glass tank, a suitable plastic length or rubber tube, which is tightly sits onto the bleeding fitting. It will be necessary to help the second person. 2. If it is not yet done, remove the dust cap of the pumping fitting and suck the tube prepared for pumping. Immerse the second end of the tube in the brake fluid pre-polly in the reservoir. 3. Ensure that the main cylinder tank is filled and maintain the liquid level in it above the "min" line throughout the procedure. 4. Ask the assistant to press the brake pedal until it stops several times, and then keep it pressed. 6. Repeat this procedure (paragraphs 4 and 5) until the flowing brake fluid is free from air bubbles. If, when pumping the first of the brake mechanisms, all the liquid merged from the main cylinder, fill the main cylinder and re-pump the brake, making breaks between cycles of approximately five seconds. 7. Tighten the pump fitting, remove the plastic tube and install the dust cap. 8. Repeat the procedure for the rest. brake mechanismx in the above sequence.

Pumping with fixture with non-return valve

Pumping under pressure

Order procedure

1. These devices are powered by compressed air contained in the chamber of the spare wheel. However, note that the air pressure must be reduced (see the instructions attached to the device). 2. Connect the incoming container-filled container to the brake fluid to the main cylinder tank and to the spare wheel. Perform pumping, alternately opening the fittings (in the specified sequence) and merging the liquid until it is free from air bubbles. 3. This method has advantages, because A large amount of fluid in the installed tank prevents air from entering the main cylinder during pumping. 4. Pumping under pressure is especially effective when pumping "problem" systems ( airlock Stuck in the place where it is difficult to expel it) or with complete pumping of the system during the next replacement of the liquid.

All methods

Order procedure

1. Upon completion of pumping, wash the spilled liquid, tighten the pumping fittings in the specifications to the effort and install their dust caps. 2. Check the brake fluid level in the main cylinder tank and bring it to the norm, if necessary (refer to the section). 3. Pour the brake fluid released when pumping, it is not suitable for reuse. 4. Check the brake pedal elasticity. If there are failures during its movement, there are still air in the system and further pumping is required. If re-pumping did not bring a satisfactory result, the seals of the main cylinder may be worn.

Models equipped with ABS

Before pumping brake hydraulic systems on models with ABS, preparatory procedures must be carried out and adopt special precautions. These procedures vary depending on which part of the system is disconnected.
Information relating to the usual brake system (except for pumping under pressure) is applicable to models equipped with ABS. However, this models use another pumping sequence:
a) left front brake mechanism
b) Right rear brake mechanism
c) right front brake mechanism
d) left rear brake mechanism
In addition to this, the following pumping procedures are used.

Pumping after separation of the connecting clutch of the wheel cylinder / caliper

100% "border \u003d" 0 "bgcolor \u003d" # Eeeeee "CellPadding \u003d" 3 "CellSpacing \u003d" 0 "\u003e

Order procedure

1. Connect a container with pumping fitting and bring the fluid level to the norm in the main cylinder reservoir. Do not forget to support it above the MIN label throughout the procedure. 2. Open the pump fitting, then ask the assistant to close the brake pedal and hold it in this position. Tighten the fitting and ask the assistant to slowly release the pedal and wait approximately 3 seconds. Repeat this procedure at least ten times until the fluid arising from the pumping fitting is not free from air bubbles. 3. Again, ask the assistant to press several times on the brake pedal and keep it pressed. Open the pumping fitting and let the pedals go down to the floor. Tighten the fitting and ask the assistant to slowly release the pedal and wait at least 3 seconds. Repeat this procedure and make sure that the flowing fluid is free from bubbles. 4. Check the brake pedal elasticity, then remove the container and bring the fluid level to the norm (refer to the section Current service schedule). Make sure that the pump fitting is clamped by the regulated tightening force, then install the dust cap.

Pumping field of disconnection of couplings regulating pressure

Order procedure

1. Pump both rear brakes as described above. Pumping after separation of the main cylinder coupling 2. If the main cylinder was disconnected, it must be pumped before connecting it to the hydraulic line so that the air does not get into the hydraulic unit. For this, two plugs are required, which are screwed into the openings of the main cylinder. 3. Screw the plugs in the ports of the main cylinder and tighten them. 4. Fill in the cylinder tank, then open the rear cap / fitting (first circuit) and ask the assistant to press the brake pedal and hold it in this position. Tighten the plug, then ask the assistant to slowly release the brake pedal and wait approximately 3 seconds. Repeat this procedure 5-6 times. 5. Repeat the procedure for the front of the main cylinder (second circuit). 6. To prevent the fluid yield from the cylinder, and consequently, air penetration before removing the plugs, ask the assistant to slightly press the brake pedal (approximately 30 mm) and hold it in this position. 7. Remove the plugs from the brake pipes and make sure both tubes are filled with liquid; If this is not the case, the fluid in them. Quickly remove one of the main cylinder plugs (brake pedal is held as described in the previous paragraph), connect brake tube And tighten the connecting nut in the specification in the Specifications. Repeat the procedure on the second channel of the main cylinder, then wash the spilled liquid. 8. Refer to paragraphs above and completely pump the brake hydraulic system in the above sequence.

Pumping after disconnecting the coupling of the hydraulic unit
