Bleeding brake system hydraulic drive
Brake circuit is pumped to remove the air, got there at filling liquid after its replacement or repair after the hydraulic drive units associated with its depressurization. Signs of air in the hydraulic drive: - An increase in pedal travel, its "soft" one press on the pedal; - A gradual reduction in pedal travel while increasing its "rigidity" when pressed repeatedly on the pedal. Before pumping hydraulic drive is necessary to find and eliminate the cause depressurization.
HELPFUL ADVICE If pumping hydraulic drive is associated with the repair of a single circuit and obviously known to the serviceability of another circuit, it is admissible only repaired pumping circuit. |
Actions when pumping hydraulic drive are the same as in the replacement of the brake fluid (cm. "Brake fluid"). The only difference is that the criterion of complete leveling of the wheel cylinder is to stop the release of air bubbles from the hose, not the appearance of a fresh brake fluid.
