8.14. Pumping of brakes


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

When dismantling a hydraulic actuator of one wheel it is possible to be limited to pumping only an understanding contour.

Press several times a pedal of a brake and remove residual depression in the amplifier.

Before pumping restore liquid level in a tank and during pumping support level, without allowing a tank opopustosheniye. Fill in only fresh liquid.

1. Pumping begin with a back right wheel. Attach to the union a hose, other end of a hose lower in a vessel with brake liquid.
2. Ask the assistant to press slowly a pedal of a brake and to hold.
3. Unscrew the union and later 2 seconds after the stream of liquid following with bubbles will weaken, tighten the union. Ask the assistant to release a pedal.
4. Repeat procedure until then while in following liquid vials will not cease to be observed. Tighten the union.
5. Execute these actions in sequence: left back wheel, right forward, left forward, pressure regulator. Upon termination of restore liquid level in a tank.
6. Check rigidity of a pedal and work of brakes.


If a pedal "soft", repeat pumping. If to remove air it is not possible, air hit in ABS system valves can be the reason. Therefore, if a pedal "soft" after repeated pumping BRAKE or ANTI-LOCK lamps also burn, tow off the car in car-care center for check by the scanner.
