It is often caused by the deformation of the brake friction lining or the brake disc, which is related to the material, processing accuracy and thermal deformation of the brake friction lining and brake disc. The main reasons are the uneven thickness of the brake disc and the brake disc. Poor roundness of the drum, uneven wear of the brake pads, thermal deformation and hot spots, etc. To
In addition, the deformation or improper installation of the brake caliper, and the unstable friction coefficient of the brake lining can also cause jitter during braking. In addition, if the vibration frequency generated by the brake friction pad during braking resonates with the suspension system, it will also cause jitter.
