Replacement of a brake liquid

It will be necessary for carrying out of work for you:

- Nakidnoj key for the union of removal of air. For example, HAZET 1968-7.
- Transparent plastic hose in internal diameter of 6 mm and capacity for gathering of a brake liquid.
- About 1.0 l of a brake liquid.

Application of a brake liquid of specification DOT 5 is not supposed. It is not necessary to fill in in system a liquid were in the use.

Observe rules of the reference with a brake liquid, address to Section the Brake liquid - the basic data and security measures.

Protect environment, at all do not pour out the fulfilled oil and do not delete it together with a household waste. Local authorities should inform on the locations of the nearest points of reception of the fulfilled materials.


The brake liquid through a time of brake hoses, and also ventilating apertures of the tank of a liquid absorbs a moisture. Thereof while in service there is a decrease in temperature of boiling of a brake liquid. At considerable loading on brakes it can lead to formation of vials of steam in brake pipelines that reduces efficiency of action of brakes. Therefore it is necessary to replace a brake liquid each 2 years.

1 Observe rules of the reference with the brake liquid, stated in Section the Brake liquid - the basic data and security measures.

On HUNDRED air from hydrosystem of brakes, as a rule, leaves by means of the special device. The device submits a brake liquid to the tank under the pressure of 2.0 bar. It is possible to spend this operation and without application of the special tool. In this case air from brake system leaves качательными movements of a pedal of a brake. Operation is carried out by means of the assistant.

If air has got into hydroblock ABS, it is recommended to remove it on HUNDRED. It takes place at presence негерметичности the hydroblock or in a case опорожнения one chamber of the tank of a brake liquid or if at removal of air from system have forgotten to add a liquid.


2 Note liquid level on the tank. After liquid replacement restore former level of a liquid. Thus, the modulation of the tank is excluded by a liquid at replacement brake колодок.
3 Suck away a liquid from the tank to level of 10 mm.

Do not empty completely the tank that air has not got to brake system.


4 Fill the tank with a fresh brake liquid to mark MAX.

Cautiously open unions for removal of air so that not to turn out them. It is recommended to spray unions approximately for two hours before opening by rust solvent. If any union does not turn away, it is necessary to address on HUNDRED.


Sequence of removal of air

1. A support the back right.
2. A support the back left.
3. A support the forward right.
4. A support the forward left.

5 Put on the union of the right back brake cylinder a pure hose and substitute the corresponding capacity.
6 Ask the assistant to press a brake pedal so that to feel resistance slowly.

7 Keeping a brake pedal in the pressed condition, turn away the union накидным a key-1 on the right back support. Close the union when the pedal will concern a floor. Ask the assistant to release a pedal.


8 Repeat the described procedure so much time, how many it is necessary that the leaving liquid did not contain bubbles. The fresh liquid is learnt on light colour.
9 Slightly tighten the union. The inhaling moment depends on diameter of a carving: the union in diameter of 7 mm is tightened by the moment 5 Н•м, diameter 11 mm the moment 15 Н•м.
10 Similarly, in the order specified above, pump out a brake liquid from other supports.

In the course of air removal add a liquid in the tank. It should not be emptied completely. Otherwise air gets to system.


11 After replacement of a brake liquid press a pedal of a brake and check up its free wheeling. It should not exceed 1/3 general courses of a pedal.
12 Cars with РКПП: As the coupling drive works on a brake liquid, liquid replacement in coupling hydrosystem is made in the way described above.
13 Before replacement of a brake liquid fill it in the tank to noted level.
14 Screw a cover on the tank.

Carry out the safety control:

- Whether brake hoses are fixed?
- Whether the brake hose in the holder is fixed?
- Whether unions for air removal are tightened?
- Whether enough of a brake liquid is filled in?
- On the working engine check up tightness. For this purpose press a brake pedal effort 200 – 300 Н (20 – 30 kg) during 10 with. The pedal should not weaken. Check up all joinings on tightness.


15 In summary brake some times on road with a rare traffic. Thus at least once execute full braking at which works ABS, in particular, on a ground. Work ABS is felt on pulsations of a pedal of a brake.

Thus watch closely a transport following you.
