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 you press 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 for the replacement of brake fluid as described in Sec. 4 "Maintenance" (see. "Replacing the hydraulic fluid in hydraulic brake and clutch"). The only difference is that the criterion for complete pumping of the working cylinder is to stop air bubbles from the outlet of the hose, not the appearance of the fresh brake fluid.
