6.2.3. Air removal from brake system

NOTE
Air it is necessary to delete every time when tubes of brake system were disconnected from a hydraulic actuator of brakes.

If the pipeline of hydraulic system is disconnected from the main cylinder, removal of air needs to be begun with the most distant from the main brake cylinder of the working cylinder and to pass to the following most distant executive cylinder while air will not be removed from all four cylinders.
If the point of separation is in any place, except the main cylinder, removal of air needs to be begun in a point closest to a place of separation and to pass to the following next executive cylinder while air will not be removed from all four cylinders.
Uncover the union for removal of air and attach a vinyl pipe to the union.
Place other end of a vinyl pipe in the transparent container filled with liquid.
One person should press a brake pedal several times and then hold her in the pressed situation.

Weakening of the union for air removal
Fig. 6.9. Weakening of the union for air removal


The second person should weaken the union for air removal, merge liquid and tighten the union, using the special adaptation (fig. 6.9).
The inhaling moment – forward wheels: 9,8 N · m.
The inhaling moment – back wheels: 8,8 N · m.
Repeat pumping operation until the exit of air vials from a tube will not stop.
Remove air from each knot as it is described above.
After air removal, check the following:
– action of brakes;
– leakage of liquid;
– liquid level.
