Why does abnormal noise occur when braking? The probability of these reasons is the highest
Some car owners will find that when they use the car, they will make some abnormal noises when they step on the brake. So why do they make abnormal noises?If there is a sharp friction sound when braking, it may be related to the brake pads. The brake pads may be worn to the extreme. It is better to go to the repair shop to replace the brake pads in time. Otherwise, the brake will not be very sensitive, and the brake disc surface may be scratched. The brake pads are consumables. The replacement cycle varies greatly according to the driving habits of the car owners
If there is a hissing noise when braking, it may be caused by severe wear of the brake disc. If the grooves on the surface of the brake disc are too deep, there will be deviation in the fit with the brake pads, causing abnormal noise. If the wear is too serious, it is often accompanied by abnormal noise when turning.
If the car makes an abnormal noise when slowly stepping on the brake, but there is no abnormal noise when suddenly stepping on the brake, it means that there are hard metal particles on the surface of the brake pads, or the metal particles fall off and have not been treated in time. Just step on the brake several times to keep the discs clean.
