Where is the Brake Disc Wear Limit Indicator Located?
1 Answers
The three grooves on the surface of the brake disc serve as the wear limit indicators. When these three grooves are worn flat, it's time to replace the brake disc. Alternatively, you can use professional tools to measure the remaining thickness of the brake disc and compare it with the standard thickness. If the wear reaches 2mm, it indicates that the brake disc has reached its wear limit. Below is relevant information about brake discs: 1. Replacement timing: Brake discs typically need replacement after a vehicle has traveled 60,000-80,000 kilometers, though this isn't absolute. The wear condition of brake discs is closely related to the road conditions and driving habits of the owner. If the owner frequently drives in mountainous areas or congested urban roads where braking is more frequent, the wear on the brake discs will be greater, shortening the replacement cycle—sometimes requiring replacement before reaching 60,000 kilometers. Conversely, if the owner primarily drives on highways where braking is less frequent, the service life of the brake discs will naturally be longer. 2. Methods to determine replacement: If professional tools aren't available to measure the wear level of the brake disc, you can also judge the depth of scratches by touching the edge of the brake disc with your hand. If the edge becomes relatively sharp and there are obvious scratches on the surface, this indicates severe wear and the need for timely replacement. Note: Do not touch the brake disc when the car is hot, as it can easily cause burns.
