8.10. Removal of air from a hydraulic actuator of brakes


Need of pumping arises after a detachment of tubes of the main cylinder or at strong lowering of the level in a tank.

When dismantling a hydraulic actuator of one wheel it is possible to be limited to removal of air only from the understanding cylinder.

If the highway from the main cylinder to wheel understood, then it is possible to be limited to removal of air only from this highway.

1. Press several times a pedal of a brake and remove residual depression in the amplifier.
2. Before pumping restore liquid level in a tank and during pumping support level, without allowing emptying of a tank. Fill in only fresh liquid.
3. Prepare liquid, a vessel, a hose for pumping and a key for an union otvorachivaniye.
4. Begin pumping with a back right wheel.
5. Attach a hose to the union, lower other end of a hose in a vessel with brake fluid.
6. Ask the assistant to press slowly several times a pedal of a brake and to hold.
7. Unscrew the union, and later 2 sec. after the stream of the liquid following with bubbles will weaken, tighten the union. Ask the assistant to release a pedal.
8. Repeat the procedure until in the following liquid vials of air do not cease to be observed.
9. Tighten the union.
10. Perform these operations in the sequence: left back wheel, the right forward, left forward.
11. Upon termination of pumping restore liquid level in a tank.
12. Remove air from pressure regulator (dosing and perepuskny valves), having repeated the actions stated above (1 – the union for pumping).
13. Check rigidity of a pedal and work of brakes.
14. If necessary repeat the procedure.
