Replacement of brake liquid


Necessary special tool: A cap key of 10 mm for an otvorachivaniye of the union of pumping of brakes.

Brake liquid through a time of brake hoses and through a ventilating opening of the tank of liquid soaks up air in system. Thereof the boiling point of brake liquid in use goes down. At big brake effort it can lead to production of steam in brake pipelines that essentially reduces efficiency of action of brakes.

Brake liquid should be replaced each two years, it is recommended to do it in the spring.

At work with brake liquid it is necessary to observe security measures, address to the Section Brake liquid.


1. Suck away brake liquid from the tank to level of 10 mm.

Completely do not suck away liquid from the tank that air did not get to system.

2. Fill in in the tank new brake liquid to Max mark.
3. Put on the union of pumping of the right back support a pure hose and substitute capacity.

4. Ask the assistant to press several times a brake pedal so that antipressure was felt. Holding a pedal pressed, a cap key (1) unscrew the union of pumping and let out liquid through a transparent hose. Close the union when the pedal will concern a floor. Release a pedal. Address to an accompanying illustration. This process repeat so many time (about 10 times), how many it is necessary, that from system new liquid went. New liquid can be learned on more light color.

5. Close the union. Fill the tank with new brake liquid.
6. Similarly extort liquid from other supports. Sequence following:
   1-the back right;
   2-the back left;
   3-the forward right;
  4-the forward left.

Following brake liquid should be pure and not contain air vials.

7. Similarly replace brake liquid in coupling hydrosystem.

8. Remove air from coupling, address to the Section Removal, installation and coupling check.
9. It is necessary to hand over the fulfilled brake liquid in special point of reception.

Brake liquid should not get by no means to capacities for drinking water. It is necessary to exclude contact of children to brake liquid. Danger of poisoning!
