Why does the car shake when braking?

[McCameron]

The reasons for car shaking when braking are as follows: 1. Uneven wear of the brake disc, meaning severe one-sided wear. This is caused by the vehicle's own issues, mainly due to poor retraction of the brake caliper. Car braking is achieved by two friction pads pressing against the brake disc through the brake caliper to create friction and braking effect. Since the brake is only connected to the inner friction pad, incomplete retraction of the brake caliper after braking can lead to increased one-sided wear. 2. Daily driving habits. Continuous braking generates high heat in the brake disc, and sudden hard braking at this point may disrupt the dynamic balance of the brake disc. Brake discs are made of cast iron, which has good stability, but improper operation can still cause deformation. 3. Use of low-quality brake pads. Inferior brake pads contain a large amount of metal substances. When these metal substances come into contact with the brake disc, due to their hardness, the brake pads wear more slowly (they are designed to wear) but also reduce the service life of the brake disc.
