[LaMackenzie]

Here are the methods to deal with grooves on the surface of brake discs: 1. If the grooves are not deep. You can remove the brake pads and smooth them with coarse sandpaper, then reinstall the polished brake pads. During use, the grooves on the brake discs can be eliminated. 2. If the grooves on the brake discs are deep. You can remove the brake discs and take them to a lathe workshop to grind off the grooves, which is known as resurfacing the brake discs. After installation, they can continue to be used. 3. If the grooves reach the wear limit. The brake discs need to be replaced. The following are the reasons for grooves on brake discs: 1. The brake pads are too hard, or the brake pads are severely worn, exposing metal parts that directly rub against the brake discs, causing grooves. At this time, there should also be a screeching sound. 2. There are sand particles or metal debris between the brake pads and discs, causing grooves after friction. 3. Normal wear of the brake discs. The maximum wear limit for brake discs is 2 millimeters. After reaching the limit, it is necessary to replace the brake discs with new ones.
