What to do if there are scratches on the brake disc?
1 Answers
As long as the scratch depth does not exceed 0.6 millimeters, it's not a big issue. The causes of deep scratches include: 1. Driving habits: Only the front or rear brake discs have grooves. This situation is generally caused by driving habits and frequently uneven distribution of braking force between the front and rear. 2. External force: Only one brake disc has grooves while others are normal, usually due to material issues or external forces causing this. 3. Possible factors: Foreign objects getting stuck between the brake disc and brake pad, coinciding with heavy braking; uneven force distribution of the brake caliper; manufacturing defects in the brake pads, resulting in uneven mixed materials, making the brake pads too hard or containing large metal particles.
