11.2. Removal of air from the brake systemAfter carrying out repair of the brake system during which its opening was made air can get to system. In this case air needs to be removed from system. A sign of existence in pipelines of system of air is the brake pedal pliability when pressing it. In this case it is necessary to eliminate leakage and to remove air from system.
On HUNDRED brake system it is, as a rule, filled with liquid, and air from it is removed by means of the special device.
When using of the specified adaptation pressure of filling of system should not exceed 1 atm. This operation can be performed as well without the specified device. In this case air from the brake system is removed by kachatelny movements of a pedal of a brake what requires the help of the assistant.
If air got into any separate brake cylinder, it is necessary to delete air from all brake system and by that from each wheel cylinder. If only one support, as a rule, is replaced or under repair it is sufficient to remove air from the corresponding brake cylinder.
The remark on security measures
If one of cameras of the tank of brake fluid (for example, with leakage in the brake system is completely emptied or if during removal of air forgot to add liquid in the tank), in system air which gets to the pump ABS is sucked in. Air from the brake system in this case has to be removed on HUNDRED with use of the special device.
Sequence of removal of air: back right brake, back left brake, forward right and forward left brake and working cylinder of coupling.
