How to deal with abnormal noise and squealing of brake discs

First of all, the presence of rust on the brake disc may be one of the main causes of abnormal noise. When water adheres to the brake disc and is parked for a long time, rust will easily form on the surface of the brake disc. At this time, we will hear a sharp and harsh sound when we brake. To solve this problem, we only need to drive a certain distance and apply the brakes lightly to help the water evaporate and eliminate the abnormal noise.

Secondly, excessive brake pad wear can also cause the brake disc to squeak abnormally. Since the brake pads are consumables, when the brake pads are severely worn, the iron plate of the brake pads will rub against the brake pads, causing abnormal noise. The solution to this problem is very simple, just replace the brake pads and it will be back to normal.

In addition, installing the brake pads backwards is also one of the reasons for the abnormal noise and squealing of the brake disc. If the brake pads are installed backwards or misaligned, it will cause abnormal noise when braking. To fix this problem, simply reinstall the brake pads correctly to eliminate the squeak.

Another common situation is that new brake pads will make abnormal noise during the break-in period. For new car brake pads, there will be abnormal noise when braking during the running-in period, but it will return to normal after the running-in period. Therefore, if your brake pads are newly replaced, wait patiently for a while and the abnormal noise will disappear naturally.
