What Causes the Car to Shake When Braking?

[LeCameron]

The specific reasons for car shaking during braking are as follows: 1. Uneven wear of the brake disc, also known as one-sided severe 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 caliper's force, creating friction for braking. Since the brake is only connected to the inner friction pad, incomplete retraction of the caliper after braking can lead to aggravated one-sided wear. 2. Driving habits. Continuous braking can generate high heat in the brake disc. If hard braking is applied at this moment, it may disrupt the dynamic balance of the brake disc. Brake discs are made of cast iron (pig iron), which has good stability, but improper operation can still cause deformation. 3. Use of low-quality brake pads. Inferior brake pads contain more metal, making them harder and more prone to resonance when rubbing against the metal brake disc, amplifying vibrations and causing shaking.
