How to Adjust Oil Brakes That Don't Hold?

[OZoey]

Start the vehicle, press and release the brake pedal repeatedly for about ten times, then press the brake pedal all the way down and hold it. The person outside the vehicle should quickly loosen the bleeder screw, keep it loose for two seconds, and then tighten it. The person inside the vehicle continues to press the pedal, and once it's pressed down, the person outside loosens the bleeder screw again, then tightens it. Repeat this process several times until the fluid coming out of the bleeder screw is free of air bubbles. More details are as follows: 1. All four wheels need to be bled: During this process, pay attention to whether the brake fluid is insufficient. If it is, you need to add more brake fluid. 2. After bleeding the air: If the brake pedal is not high enough, you can continue bleeding. Once completed, reassemble everything, and this should resolve the issue of soft brakes or the brakes not holding when pressed all the way down.
