The first thing to say is that as long as the wear difference between the left and right brake pads is not very large, it is normal. You should know that the car on different roads, different corners of the four-wheel force, speed and so on are not consistent, braking force will be inconsistent, so the brake skin wear deviation is very normal. And most of the ABS systems of today’s cars have EBD (electronic braking force distribution), and some are more standard with ESP (electronic body stability system), and the braking force of each wheel is “distributed on demand”.
First, the working principle of brake pads
Each wheel brake pad is composed of two inner and outer parts, which are connected by two telescopic rods. When stepping on the brake, the two brake pads hold the brake disc. When releasing the brake, the two brake pads move along the telescopic rod to both sides and leave the brake disc.
Second, cause the left and right brake pad wear how inconsistent causes
1, the speed of wear is mainly with the brake disc and brake pad material has a direct relationship, so the brake pad material is not uniform is a possibility.
2, often turn the brake, the force of the left and right wheels is unbalanced, which will also lead to inconsistent wear.
3, one side of the brake disc may be deformed.
4, the brake pump return is inconsistent, such as one side of the pump return bolt dirty.
5, the length difference between the left and right brake tubing is a little large.
6, the telescopic rod is sealed by the rubber sealing sleeve, but if the water or lack of lubrication, the rod can not be freely telescopic, the outer plate after the brake can not leave the brake disc, the brake pad will be extra wear.
7, the left and right sides of the brake braking time is inconsistent.
8. Suspension problem.
It can be seen that, in general, this situation should be caused by insufficient unilateral braking or unilateral dragging. If it is the same wheel of two brake pads wear uneven, should focus on checking whether the brake pad material is consistent, brake pump return is good, pump support is deformed. If the wear between the left and right wheels is uneven, it should be emphatically checked whether the braking time on the left and right sides of the coaxial brake is consistent, whether the suspension is deformed, whether the suspension body bottom plate is deformed, and whether the suspension coil spring elasticity is reduced.
