What is the method for bleeding the brake pump?
1 Answers
The following is the method for bleeding air from the brake pump: 1. Remove the dust cap from the bleeder valve on the wheel cylinder, prepare a transparent hose, connect one end to the bleeder valve and the other end to a plastic container. 2. One person should press the brake pedal several times inside the vehicle, then firmly hold the pedal down, while another person loosens the bleeder screw on the wheel cylinder outside the vehicle. At this point, air will be expelled along with the brake fluid. 3. Repeat the above steps until no air bubbles are visible in the expelled fluid, then top up the brake fluid and tighten the bleeder screw. The following are precautions for bleeding the brake pump: 1. The recommended wheel sequence for bleeding is usually right rear, left rear, right front, and left front. 2. The expelled brake fluid should not be reused as it may have absorbed moisture from prolonged exposure to air, which could affect braking performance.
