Where is the wear limit indicator located on the brake disc?
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. Here is some relevant information about brake discs: 1. Replacement timing for brake discs: Generally, brake discs need to be replaced after a vehicle has traveled 60,000-80,000 kilometers. However, this is not 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 required more often, the brake discs will wear faster, shortening the replacement cycle. In some cases, replacement may be needed even before reaching 60,000 kilometers. Conversely, if the owner mainly drives on highways where braking is less frequent, the brake discs will last longer. 2. Methods to determine replacement: If we don't have professional tools to measure the wear of the brake disc, we can also use our hands to feel the edge of the brake disc to judge the depth of the scratches. If the edge becomes sharp and there are obvious scratches on the surface, it indicates severe wear and the need for immediate replacement. Note: Do not touch the brake disc directly when the car is hot, as it can cause burns.
