Brake pads are an important part of car safety, and the abnormal noise after the new brake pads may be frightening. However, this phenomenon is not inexplicable, and understanding the possible causes can help to better deal with the problem.
Reason oneVideogameblockchainRunning-in period of new brake pads
There is a certain gap between the new brake pad and the old brake disc, which needs to be run-in for a period of time to achieve the best condition. During the running-in period, there may be some abnormal noise, which is a normal phenomenon and usually disappears after driving a certain distance.
Reason 2: the surface of the brake disc is not smooth
If the surface of the brake disc is not smooth, it may cause abnormal friction between the brake pad and the brake disc while working, resulting in abnormal noise. In this case, it is necessary to check whether the surface of the brake disc is damaged or uneven and deal with it accordingly.
Reason 3: brake pads quality problems
The quality of brake pads on the market is uneven, and if you buy poor quality brake pads, it may lead to abnormal noise. When buying brake pads, you should choose a well-known brand and make sure it matches the car model.
Reason 4: installation problems
The installation of brake pads also requires some technology and experience. If the installation is not in place or improper installation, it may lead to abnormal friction between the brake pads and the brake disc, resulting in abnormal noise. When installing brake pads, ensure that they are installed in place and follow the manufacturer's instructions.
Reason 5: damage to other parts of the brake system
In addition to brake pads and brake discs, other parts of the brake system, such as brake tubing and brake master pump, may also cause abnormal noise if they are damaged or worn. Therefore, the brake system should be checked regularly and the damaged parts should be replaced in time.
How to judge the cause of abnormal noise
Abnormal noise characteristics may be caused by slight hissing, sharp screaming brake pads during running-in, or abnormal friction between brake pads and brake discs, dull impact sound, uneven surface of brake discs or damage to other parts of the brake system.In short, if the abnormal noise occurs after the new brake pads are replaced, the characteristics of the abnormal noise should be judged first, and then be investigated and dealt with according to the possible reasons. If it can not be solved on its own, it is recommended to contact a professional car maintenance shop for inspection and repair.
