Brake pads are a very important part of a car. There are many kinds of materials. Sometimes the brake pads will have abnormal noises. A few common brake noises are briefly summarized. If you encounter similar situations, you can check them by comparison. .

1. The new film is installed on the old plate. The old plate generally has grooves, and the new film is mounted on the upper and lower sides of the old plate, forming a sound.

Treatment method: The chamfering around the brake pad or the disc can be dealt with Custom Brake Lining Suppliers.

2. Install a new plate with a new plate, the flatness of the new plate or the new plate is too large, the running-in of the plate and the plate is not good, or grinding to one side causes noise.

External method: brake for a period of time, the disc and the plate are in line, and it can be dealt with. If the flatness is too large, it needs to be re-installed.

3. The brake wheel cylinder is not properly returned, and the dragging of the brake causes the organic materials of the brake pads to volatilize early, causing the car to drive for a period of time, which will cause noise.

Treatment method: Check the maintenance of the sub-cylinder, check whether the brake pads are intact, if there are burning pads, replace the brake pads.

4. During the process of traveling, sand and gravel enter the film, and there are water marks on the brake disc in the rainy season, and fine sand particles will cause noise.

Treatment method: Remove the brake pads and sort out the sand. If there is still a small amount of sand, the natural conflict will disappear after a period of time.

5. The brake pads show low-frequency abnormal noise when the car is cold and at low speed. In rainy seasons and humid environments, the discs and sheets form an oxide layer, which simply causes abnormal noise.

Brake pad manufacturer's treatment method: After many times of braking, the abnormal noise will be eliminated.

6. When the car is cold in the morning, if you don't step on the brakes, you can sometimes hear the slightest noise.

Treatment method: Generally, the models without brake return springs have some such problems, and the abnormal noise will be eliminated after several times of braking.

7. There is abnormal noise when reversing the brakes. Since most of the braking work is to move forward, some brake pads will form some burrs. Therefore, when the brakes are reversed, the burrs and the brake disc conflict with abnormal noises.

External method: This situation can be left untreated, or it can be removed and polished.

8. There are obvious hard debris in the brake pad conflict material. This kind of hard debris will cause a lot of scratches on the brake disc and cause noise.

Treatment method: Remove the brake pads, you can clearly see the protruding hard spots, use a needle to lift the hard objects, polish and clean them, or replace the brake pads with new ones.

9. The problem of conflicting data formula or the problem of unqualified data entering the factory constitutes a problem.

Treatment method: replace the new brake pads with qualified quality in time

The effect of brake pads should not be underestimated. It is directly related to the life and safety of the car owner. If the brake pads are in any condition, they must be inspected and dealt with immediately. What are the easiest reasons to be ignored when there is an abnormal sound?

In addition to normal wear and tear, small sand grains may also be the culprit behind the abnormal sound of the brake pads. When the vehicle is traveling, there will be very fine sand particles entering the middle of the disc and the disc, and there will be abnormal noise due to the conflict. Of course, there is no need to worry about this situation, just run and let the small sand particles fall out.

There is also a special situation - if the new brake pads are not run in well, there will also be abnormal noises. The newly replaced brake pads will be relatively hard, and will be better after about 200 kilometers. Some car owners will speed up and slam on the brakes to achieve the effect of running in the brakes in a short time. However, this will reduce the service life of the brake pads. It is recommended to run for a while to investigate this situation, and not to artificially force the wear of the brake pads.

In fact, in addition to the brake pads, there are many reasons for the abnormal sound of the brake system, such as the operation of the device, the brake disc, the brake caliper, and the suspension of the chassis may cause abnormal sound. Habits, to prevent damage before it happens.
