Replacement of brake fluid


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

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

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

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


1. Suck away brake fluid from the tank to the 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 fluid to the mark Max.
3. Put on a pure hose the union of pumping of the right back support and substitute capacity.

4. Ask the assistant to press several times a brake pedal so that counter-pressure was felt. Holding a pedal pressed, a cap key (1) unscrew the union of pumping and produce liquid through a transparent hose. Close the union when the pedal concerns a floor. Release a pedal. Address an accompanying illustration. Repeat this process so many time (about 10 times) how many it is necessary that from system new liquid went. New liquid can be recognized by lighter color.

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

The following brake fluid has to be pure and not contain vials of air.

7. Similarly replace brake fluid in a coupling hydraulic system.

8. Remove air from coupling, address the Section Removal, installation and check of coupling.
9. The fulfilled brake fluid needs to be handed over in special collection point.

Brake fluid should not get to capacities for drinking water at all. It is necessary to exclude contact of children with brake fluid. Danger of poisoning!
