What is the method for bleeding brakes?
1 Answers
Automotive brake bleeding requires two people to complete. One person needs to sit in the driver's seat and press the brake pedal with their foot to generate brake pressure. The other person should be under the vehicle to perform the bleeding. The specific steps are as follows: 1. Method for pressing the brake pedal: The person sitting in the driver's seat should press the brake pedal firmly and hold it down without releasing their foot until the person under the vehicle finishes bleeding the air. If there is a significant amount of air in the brake system, making the brake pedal feel soft, the person should quickly press and release the pedal, then firmly hold it down while the person under the vehicle begins bleeding. 2. Method for bleeding: After the person in the vehicle has pressed and held the brake pedal, the person under the vehicle should use a wrench to loosen the bleeder valve on the brake caliper to release the air, then tighten the bleeder valve and inform the person pressing the pedal to release and press it again. Repeat this process until the brake fluid coming out of the bleeder valve is free of air.
