What’s the matter with the brakes making abnormal noise?

There is a rattling sound from the abnormal braking noise. It is very likely that the ABS system is triggered by sudden braking. The rattling sound is the sound of the system when it is working. On the one hand, the failure to stop the car may be due to the excessive speed of the vehicle at that time, and on the other hand, there may be a problem with the braking system.

　　

When the speed of the car is faster, the braking distance is longer, and it is easier to feel that the car cannot be stopped. It may also be that the brake pads are more worn, the brake pads are relatively thin, and the proper braking performance cannot be achieved, or there are oil stains on the brake pads, resulting in a decline in braking performance. The abnormal noise of the brakes may not be a problem with the components of the vehicle itself, or it may be that the brake system has not yet completed heating up when the car is cold. Before reaching the working temperature, the brakes may produce abnormal noises; In rocky areas, some gravel may be carried on the brake pads and discs of the vehicle, and abnormal noise will also be produced when braking. The brake pad is an important part in the vehicle braking system, so the brake pad needs to be checked frequently by the owner for wear or other abnormalities.
