What's going on with the screeching sound of the brakes?

When a vehicle brakes sharply, many vehicles make a clattering sound. At this point, don't worry, it's normal. You just have to keep on the brakes.

When the car brakes sharply, when this sound occurs, it is generally THAT ABS is working, and when ABS is working, the pressure cylinder will make a slight clicking sound.

ABS is also called anti-lock death. When braking urgently, in order to prevent the wheels from locking and keeping the wheels in a state where they can always roll, ABS issues instructions to keep the brake pads and brake discs in a lock-release_release_hold-release state. Then, the brake pads and brake discs are often in contact and release, and they will also make a clucking sound.

So, when this sound appears, it's generally fine, don't worry about it.

Because ABS is an active safety system that prevents the rear wheel from sliding after the rear wheel is held, and the front wheel is not moving in the direction of the rear wheel. It can effectively prevent this from happening.

However, if the brakes make a sharp or silky sound, you should pay attention. The point of failure corresponding to different sounds is not the same.

If it is squeaky and sharp and harsh, it is generally the brake pad or brake disc is over-worn, or there is a foreign body between the brake pad and the disc, etc.

If it is a banging sound, it should be caused by the loose fixing bracket of the brake calipers.

The brakes are the tools to ensure that the vehicle slows down or stops, and regular maintenance is very important.
