What's the matter with the sound of car brakes?

1. If there is an abnormal sound, there may be the following reasons: the hardness of the brake disc at the time of manufacture is different, resulting in different degrees of wear, which will not have much impact.

2. The reasons for the abnormal sound of car brakes are as follows: Brake running-in: There will be a running-in period for new cars or newly replaced brake discs. During the running-in period, there will inevitably be some abnormal noises. Therefore, if you need to grind it, the brakes will have abnormal noises at this time, which are divided into vibration friction and sharp silky sounds. Generally, they will disappear after running for hundreds of kilometers. Divide.

3. Normal noise phenomenon. Brake pads are composed of iron pads, graphite, asbestos, etc. When they rub against the brake discs, they will inevitably produce some metal powder. At this time, people will make some squeaky sounds when they step on the brakes.Solution: The noise of the vehicle will be reduced for a period of time.

What to do if there is a strange sound in the car brake

1. When this happens, it proves that your brake pads have been worn excessively and must be replaced. If you don't replace it, not only the huge noise will be unbearable, but also the braking force The problem of a sharp decline increases the security risks. Generally, the brake pads can be replaced for 50,000-60,000 kilometers, but they will vary according to different driving habits.

2. The brakes of the car squeak. Solution: The alarm chip will make a sharp sound and prompt to replace it. Under normal circumstances, the car brake system basically has its own set of alarm systems to warn friends to change the brake pads.

3What's wrong with the abnormal sound of brake pads? Brake pads are one of the common wear parts in cars and are used to brake vehicles. If the brake pads have an abnormal sound, it may mean that they need to be replaced or maintained. This article will explain the reason for the abnormal sound of brake pads and possible solutions.

4. In this case, we just need to polish the surface of the brake pad and grind off the hard points. In general, the abnormal noise of car brakes is mostly caused by the above situations. If the brakes keep ringing, we need to consider whether the brake pads are worn out and whether to replace the new brake pads.

5. The solution is to wait for the end of the running-in period, and the squeak will disappear. If it is not a new car, the squeaking sound when the car brakes may be due to excessive wear of the brake pads. After all, the brake pads are consumables that need to be replaced regularly.

Why brake noise

If there is abnormal noise, there may be the following reasons: the hardness of the brake disc at the time of manufacture Different degrees lead to different degrees of wear, which will not have much impact.

The reason for the abnormal brake noise may be that the brake pads are worn and need to be replaced in time. Brake pads are consumables, and they will gradually become thinner during the use of the vehicle.When the friction layer is reduced to a certain extent, the limit iron of the brake pad will sound an alarm, prompting the driver to replace the brake pad to avoid safety accidents.

The abnormal sound of car brakes is caused by the following reasons: brake disc or brake pad rust.
