Exploiting the car, there are situations where torkemose do not work effectively, braking process is carried out smoothly. In most cases, the cause is the air trapped in the system. In order to restore proper functionality necessary to remove it. You will need a suitable liquid, the key to the exhaust valve or a conventional wrench, clean container and partner. Using the braking system EBD, ABS and BA, in case of such problems, it is better to use the services of professionals.

Car preparation for pumping the brakes

Before you begin pumping the brakes in a car is necessary to begin to prepare the tools and materials for the pumping, set the location of the brake fitting front and rear wheels, an expansion tank of the main brake cylinder in the engine compartment.

The car is fixed at the observation well.After that, it should be lifted with a jack, lifts the other side of that is pumped.

If there is no inspection pit, in extreme cases, work can be done by creating a more comfortable environment.

for pumping the brake tool

Prepared, ie must be brake fluid, a rubber hose with a diameter of 5 mm, a small plastic bottle, defined with the key used.

Then fitting is unscrewed. We must start with the long wheel.

When unscrewing the head of the union can use the special keys that eliminate the risk of injury.

Here is meant protection from the cutting head of particles, which is very often the case when using tools that are not suitable for this purpose.

Failure of the screw is a cause circulation to the professionals.

If there is a tight of the unscrewing of the fitting, or in general the absence of any progress, spray is applied to the thread.

For example, it can be WD-40. Restoring its mobility, it is spinning back, but not to the end.

The next step is the use of the hose.

He is put on the fitting.

The other end is placed in a container with brake fluid to detect traces of gaseous substances in the system (air).

In the absence of contour, the bank is substituted so that the contents do not fall on the floor.

How to pump brakes

Your partner carries out the brakes 2-3 times sharply presses the brake pedal.

But, in advance, you should make sure that the car is fixed.

It should stand on a flat surface, the wheels are supported in case of possible movement.

It is worth noting that the car must be put on the "speed", i.e., use one of the gears (first transmission).

Also, pre-emphasized the attention on the following.

There are rear disc brakes equipped with pressure sensors.

If this mechanism is malfunction and raised, the brake pumping is impossible.

Some systems included an additional exhaust valve in the pressure regulator.

He also pumps out.

After all processes, the performance of the regulator is restored.

Procedure for pumping the brake system

By pumping, it is worth adhere to the following schemes.

The first parallel.

Here the wheels are hampered in turn.

First, the process is carried out on the rear group of the wheels.

Observing the sequence: Right, left.

Then the front group, the sequence is identical.

The second diagonal scheme.

It is clear from the name that the sequence is carried out diagonally.

At the same time, strictly follow the order: rear right, front left, rear left and front right.

Pumping the brakes 2-3 times, the pedal remains ground below.

At that moment the fitting is unscrewed.

As a result of the pressure formed, the substance will begin to flow. Finding air in the system is determined by bubbles.

They are more accessible visibility when using cans.

The intake valve is delayed, only after that the brake pedal is released.

If you do not do the manipulation data, the air bubbles will appear again, since the release of the pedal is delayed forcibly.

The process is carried out several times, interacting with a partner. Repeat it until all air, from the brake system, will not disappear.

For insurance, the liquid is fused into the expansion tank of the main brake cylinder, to the maximum mark.

Without making it, your works will not be justified.

By permitting the air to enter the main brake cylinder, the process of pumping is carried out in it again. If there is an inlet valve, the procedure is carried out through it.

The brakes of every wheels are hammered until the proper result is achieved.

It is very important not to forget to add fluids into the expansion tank after each process.

Filling out the expansion tank of the main brake cylinder completely, after the last pumping, test the car.

The brake pedal when pressing should be tight.

In the absence of due results, the pumping system is repeated.

It may seem that this is a very time-consuming and long-term lesson.

Nevertheless, it is enough to work the proper level and work will not show complex, as described above.

In any case, you can use the services of professionals.
