Brake discs are one of the main automotive parts provided by our company. What are the inspection methods for brake discs? Below, the editor will introduce to you:
1. The thickness of a new brake pad is generally around 1.5cm, and the thickness will gradually become thinner with continuous friction during use. Professional technicians suggest that when the thickness of the brake pads is only about one-third of the original thickness (about 0.5cm) when observed with the naked eye, car owners should increase the frequency of self inspection and be ready to replace them at any time. Of course, due to wheel hub design reasons, some models do not have the conditions for visual inspection and require tire disassembly to complete.
2. Under normal driving conditions, check the brake pads every 5000 miles. Not only should the remaining thickness be checked, but also the condition of shoe wear should be checked, whether the wear on both sides is the same, whether the return is smooth, etc. If any abnormal situations are found, immediate action should be taken. The brakes must not be replaced until the friction material is completely worn out.
3. Check the sliding performance, which can be driven at a speed of 30 miles per hour. After shifting to neutral, check the sliding distance. Generally, cars should not be less than 150 meters. In addition, the vehicle's handbrake should also be checked for sensitivity, to see if there is any slipping, and to see if there is any abnormal noise from the brakes.
4. If there is a faint sound of "iron rubbing against iron" while lightly applying the brake (which may also be caused by the brake pads running in at the beginning of installation), the brake pads need to be replaced immediately. Because the limit markings on both sides of the brake pads have directly rubbed against the brake disc, it proves that the brake pads have exceeded their limit. In this situation, when replacing the brake pads, it is necessary to cooperate with the inspection of the brake discs. When this noise occurs, the brake discs are often damaged, as shown in the following figure. Even if the brake pads are replaced with new ones, the noise cannot be eliminated. In severe cases, the brake discs need to be replaced.
