see thickness The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner with the continuous friction in use. Professional technicians suggest that when the thickness of the brake pads is only about 1/3 of the original thickness (about 0.5cm), the owner should increase the frequency of self-inspection and be ready to replace it at any time. Of course, due to the design of the wheel hub, some models do not have the conditions for visual inspection, and the tires need to be removed to complete.
There is a raised mark on both sides of each brake pad. The thickness of this mark is about two or three millimeters. This is also the limit for the thinnest replacement of the brake disc. If the thickness of the brake pad is already parallel to this mark, it must be replaced. Therefore, when the thickness of the brake pads is close to this mark, the owner must observe and prepare at any time. However, it is difficult to observe accurately with the naked eye without removing the tires. At present, many models have the position of the instrument handbrake light when the brake pads are too thin. Prompted, relatively self-test is much more convenient.
TIPS: There is no strict replacement interval for the brake pads according to the vehicle environment and driving habits. Generally, it is necessary to consider replacing the brake pads after driving about 60,000 kilometers. When it is found that the brake pads are thin by naked eye observation, technicians should be asked to check during maintenance, because there will be errors in naked eye observation. Professional maintenance stations pass calipers more rigorously than naked eye observation.
