6.1.3. Removal of air from a hydraulic actuator of brakes

Fig. 6.5. Filling of a tank with brake fluid


Uncover a tank of a hydraulic actuator of brakes and fill a tank with brake fluid (fig. 6.5).

ATTENTION
At hit of brake fluid on the painted surfaces immediately wipe the spilled liquid.

NOTE
Do not press a brake pedal when pumping the brake system under pressure.

Connect a transparent vinyl hose to the union for pumping of a support of a disk brake or the working brake cylinder of a drum brake. Lower the free end of a hose in the container with pure brake fluid.
Several times press a brake pedal.

Fig. 6.6. Removal of air from a hydraulic actuator of brakes


Holding a pedal in completely pressed situation, weaken the union for pumping until the beginning of an effluence of brake fluid. Then tighten the union for pumping (fig. 6.6).
Repeat pumping until vials of air do not stop appearing together with brake fluid.
Tighten the union for pumping.
The union inhaling moment for pumping: 7–13 N · m.
