Automobile brake disc is an indispensable part of automobile braking system, so how long does the brake disc need to be replaced? Do the brake disc grooves need to be replaced? Here is a simple and clear talk for you.

First of all, the front wheel brake disc will be thicker and larger than the rear wheel brake disc. According to the manufacturer's standard, the wear thickness of the brake disc is generally 2mm, that is, after the brake disc is worn for 2mm, it needs to be replaced.

Generally, the thickness of the front wheel brake disc varies from 20 to 36 mm. The car brands are different, and the designed brake disc thickness is also different. The thickness of the rear wheel brake disc is generally 10 to 20 mm. In this way, the modified brake disc and brake pad will be thicker and more wear-resistant.

In addition to the grooving of the brake disc, some brake discs will also have serious grooves. This situation is generally caused by the following reasons. The following are the specific reasons for the grooves in the brake disc:

1. Only the front or rear brake discs have grooves.

This situation is generally caused by driving habits and uneven distribution of front and rear brake force.

2. Only one brake disc has grooves, and the others are positive. This situation is generally caused by materials or external forces.

3. What foreign matter is sandwiched between the brake disc and the brake pad, which is caused by Yihao's big foot brake.

4. Caused by uneven force of brake cylinder.

5. The manufacturing process defects of this brake pad cause uneven mixed materials, too hard brake pads or large metal particles in them.
