The causes of Mercedes-Benz braking jitter are as follows: first, the braking force distributed by the brake cylinder is uneven, which leads to uneven braking jitter; Second, wheel hub deformation and incomplete tire dynamic balance will also lead to brake jitter. Third, the D-block will brake or shake, which is probably the problem of the primer. You can pay attention to the primer of the engine and gearbox.

Brake jitter has the following reasons:

1. Roughness of brake disc, joint surface and shaft head surface Generally speaking, the flatness accuracy of brake disc, joint surface and shaft head surface is very high, especially for large brake groups. The friction of the brake shoe is large, and the brake disc is large, which will amplify the slight unevenness. According to our experience, as long as the plane of these three parts is 0. 15MM uneven, it will definitely cause brake jitter.

2. The manufacturing error of the brake disc will also lead to brake jitter. Due to the nonstandard operation in the refitting market and the irregular product channels and quality, it is difficult for some brake kits of inferior brands or imitation brands to meet the quality requirements from the manufacturing standards, and the manufacturing error has exceeded the safety range of products.

3. For the split disc, the torque difference of the connecting screws will also lead to unevenness. 4. The process of opening and opening is wrong, which leads to the uneven melting of brake pads into new brake pads, and the brake pads need to be run-in, which is also called opening. The purpose of running-in is to make the material of brake shoe evenly melt into the brake disc. Of course, if the process of opening the brake shoe is not good, oxide layers with different thicknesses will be formed in different areas of the brake disc surface, which may also lead to brake jitter.
