1. This is often caused by deformation of the brake pads or brake discs. It is related to material, processing precision and heat deformation. It includes: poor thickness of brake disc, roundness of brake drum, uneven wear, thermal deformation, hot spot and so on.
2. The vibration frequency generated by the brake pad during braking reacts with the suspension system.
3. The friction coefficient of the brake pad is unstable and high.
