What is the method for bleeding hydraulic brakes?
1 Answers
The bleeding method is as follows: 1. Remove the dust cap from the wheel cylinder, prepare a transparent hose with one end connected to the bleeder valve and the other end to a plastic container. 2. Have one person press the brake pedal several times inside the vehicle, then firmly depress it and hold. Another person should loosen the bleeder screw on the wheel cylinder outside the vehicle, allowing air to escape along with the brake fluid. 3. Repeat this process until no air bubbles appear in the discharged fluid, then top up the brake fluid and tighten the bleeder valve. Below are precautions for bleeding: 1. After performing bleeding operations or checking/refilling brake fluid, ensure the reservoir cap is properly tightened to minimize brake fluid's exposure to air, preventing moisture absorption that could degrade its performance. 2. When refilling brake fluid, do not exceed the upper limit (MAX or HIGH) marking. Brake fluid should not be mixed with other brands.
