Reasons for scratches on new car brake pads are as follows: Friction between brake pads and discs: Scratches on brake discs are caused by the mutual friction between the brake pads and discs. If the scratches on the brake discs are evenly distributed and shallow, it is a normal phenomenon; otherwise, it indicates abnormal wear. Poor quality of brake pads: If the scratches on the brake discs are uneven in depth and hard spots are found on the brake pads, it indeed indicates poor quality of the brake pads. Friction caused by sand particles: Another possibility is that when the vehicle drives through water, small sand particles may flow into the gap between the brake pads and discs with the water. If these particles are harder than the friction material of the brake pads, they can cause uneven wear on the brake discs.
