How is the brake not working after the replacement of the brake pad?

After the car replaces the brake pads, the reason for the brake failure may be that the thickness difference between the left and right sides is too large, and the braking force will be uneven. Or it could be that one brake is dead and the other is not in place, causing the car to run away. Therefore, when replacing the new brake disc, it is necessary to carry out a long time run-in. In general, it takes about 200 kilometers to achieve a good braking effect.

Brake pads are composed of steel plate, viscous insulation layer and friction block. Due to the different degree of wear between the new brake disc and the old brake disc, the thickness is also different. Used brake pads and brake discs run in, the contact surface is large, uneven, strong braking force; The surface of the new brake pads is relatively flat, the contact surface with the brake disc is small, the braking force will drop, and the new brake pads will not stop.

New brake pad run-in method: Put on new brake pads, find a good place, accelerate to 100 km/h, and then gently step on the brake, reduce the speed to about 10-20 km/h; Then, release the brakes and drive for about 5 kilometers, so that the temperature of the brake pads and brake pads is slightly cooled. Repeat about 10 times before, basically the same.

If you only change one brake pad, the thickness of the left and right brake pads will be different, the braking force of the car will be uneven, resulting in one side of the brake, the other side is not in place, the car will run off, endangering driving safety. At present, the ABS system of most cars has EBD, anti-lock braking system, referred to as ABS. When the car brakes, the braking force of the brake can be automatically controlled, so that the wheel is in a rolling and sliding state (slip rate is about 20%), and the adhesion between the wheel and the ground is large.
