Just adjust the handbrake, normally, the brake disc will not have abnormal noise, you can remove the rear tire to see if the brake pad and brake disc are seriously worn.

The solution to the abnormal noise of the brake disc is as follows:

1. The run-in period of the new car: because the brake disc and brake pads are brand-new ridges, they have never been used, and the sound of running-in is made.

2. Foreign body ingress: foreign objects such as "fine sand" and other foreign objects enter between the brake disc and the brake pads, resulting in abnormal noise, and only need to eliminate foreign bodies during the period;

3. Corrosion: The brake disc and the brake pad are rusted and adhered together, resulting in abnormal noise, and in slight cases, only continuous braking is required during driving, and in serious cases, the brake pads and brake drums need to be replaced.

Pacific Automobile Network] The brake disc has abnormal noise and friction sound, and it is recommended to go to the 4S shop to check it. If there is a slight sound of "iron rubbing iron" at the same time as the brake is tapped, it may also be the effect of the brake disc running in at the beginning of installation), at this time the brake disc must be replaced immediately.

Because the brake disc is much higher, it is recommended that you check the brake disc frequently to avoid damaging the brake disc. When you hear the sound of the brakes, it is often too late, and the brake disc will be more or less damaged. In general, the abnormal noise caused by this will disappear after a period of wear, if the brake feels very difficult, it may be that the brake pads have basically lost friction, and they must be replaced at this time.

Bi Zhuji actually has hard spots in some bad quality brake pads, which will also produce abnormal noise. If the groove of the brake disc is deep, you can remove the brake disc to polish the groove smoothly, which is often called the brake disc, and then install it back to continue to use, but the service life will be shortened, and it is recommended to replace the brake disc directly. Generally speaking, the front brake disc needs to be replaced once for 6-80,000 kilometers, and the rear brake disc needs to be replaced about 100,000 kilometers.

Once the grooves reach the wear limit, they will affect the braking effect of the car, and new brake discs must be replaced for safety.

Low-speed through potholes, the right rear wheel has a rattling sound, a little pull a little handbrake sound disappears, went to a few repair shops and 4S shops are said that no goods can not be replaced, tell me does not affect the use, do you have a good solution to the pothole road at low speed, the right rear wheel has a rattling sound, a little pull of the handbrake sound disappears, went to a few repair shops and 4S shops are said that there is no goods can not be replaced, tell me that it does not affect the use, do you have a good solution Hello hidden old man, The main reasons for abnormal brake noise are as follows: 1. The run-in of new cars, of which the run-in of brake pads is a very important link, usually after running hundreds of kilometers, you can feel that the brakes will be more comfortable; 2. The new brake pads also need to be better combined with the old disc through running-in, and when you first put it on, you will feel that the brakes are very hard, and you usually need to drive hundreds of kilometers to feel better; 3. During the driving of the vehicle, there may be very fine sand particles into the middle of the sheet and the plate, and sometimes there will be abnormal noise due to friction, which generally does not need to be repaired. 4. For those who do not run in well and have abnormal noises, some car owners simply run up and step on the brakes, so that the brakes can be run in in a short time, but this will make the brake pads wear more severely, that is, it is equivalent to reducing the service life of the brake pads, so it is recommended to run for a period of time to observe, do not artificially force the wear of the brake pads; 5. If the fixing screw of the brake disc is lost or damaged, it will also cause abnormal brake noise; 6. If the brake system fails, it needs to be inspected and repaired. @2019

In case of water and humid environment, the brake pad and brake pad will be clamped more solidly, and the air will be emptied, and the brake pad will be tightly pressed on the pad. Abnormal noise cause 1, the brake pad of the rear wheel drum brake is problematic; 2. The handbrake line is fixed and there is a gap at the slow point, causing friction; 3. The material of the brake pad is caused by the high hardness of the metal components added; 4. There are poor assembly of nanofiber handbrake shoes and related accessories; 5、

The reasons for the abnormal sound of the brake disc are: deformation of the brake disc, wear of the brake disc, foreign objects between the brake pads and the brake disc, missing fixing screws of the brake disc, some rust of the brake disc of the car, the run-in period of the new car or the brake pads have just been replaced, etc.

1. Abnormal noise caused by brake disc deformation

The thickness of the brake disc may vary in the circumferential direction. In this case, it is necessary to repair and grind the brake disc. If it is severe, the brake disc needs to be replaced directly.

2. The brake disc is seriously worn

Severe wear of the brake disc will form deep grooves on the disc, and the friction between the brake disc and the edge of the groove will produce abnormal noise. If the groove is not deep, just grind the edge of the brake pad; If the grooves are deep, the brake disc needs to be replaced.

3. There is a foreign object between the brake pad and the brake disc

It is more common and may have foreign bodies such as pebbles or water films, which can cause abnormal noises. Generally, after driving for a period of time, the abnormal sound will slowly disappear, or you can dig forward to remove the foreign object by yourself.

4. The brake disc fixing screw is missing or damaged

Missing or damaged brake disc fixing screws can also cause abnormal braking noise.

5. The brake disc of the car is a little rusty

This is very likely to happen especially when the car is parked for a long time. It only needs to be driven safely for a while, and the rust on the surface can be wiped off.

6. The new car has just changed the brake pads during the run-in inspection period

There will be a certain abnormal sound during the run-in period of the new car or just replaced the brake pads, which is a normal phenomenon, and the abnormal sound will disappear after the run-in.
