Can the car brake disc abnormal noise 4S shop ask for accompaniment

Hello, this requires them to test and inspect, and generally this kind of wearing parts can not be claimed.

Summary. Hello, glad to answer for you. There are two ways to make abnormal noises in brake maintenance: 1. Hello, see if there are any foreign objects in the brake disc. Otherwise, it is recommended to go to the 4S store to have a look. See if there are any bumps in the plate.

2. It has been checked clearly. When the brake disc is maintained, the gap between the 4S master and the brake pad is too large. After adjustment, the abnormal noise disappears. I hope the above helps you If you are satisfied with me, please give a thumbs up <>

I did brake maintenance and there was an abnormal noise.

The solution to the abnormal noise of the automobile brake disc is as follows: 1. The problem of the material of the brake pad, the brake pad of individual manufacturers will be more hollow and hard, so it is more common to produce abnormal sound, and replace it with other brands (softer brake pads will be improved). 2. It is a problem with the brake disc, and the surface of the brake disc is uneven or there are impurities, and there will be abnormal noise.

3. It is the abnormal friction between the brake pad and the brake bracket, and the lubricating oil can be added to eliminate the abnormal noise. 4. If there is a problem with the brakes of the car, the braking system of the car must be carefully checked to avoid accidents.

Possible reasons for the abnormal noise of the automobile brake disc: 1. It may be that the repairman has misplaced the brake pad, and when removing it, it can be seen that there are only local friction marks on the surface of the brake pad. At this time, you will get the 4S shop to remove and reinstall; 2. After driving for a period of time, it suddenly sounds, most of which happen to have hard objects on the road such as sand and gravel, iron scraps, etc. clamped on the brake pads when stepping on the brakes, so you can go to the 4S shop for cleaning; 3. Due to the problems of manufacturers, the size of the friction block of the same type of brake pad is inconsistent, especially the width of the friction block, and the size deviation between some manufacturers can reach three millimeters.

This makes the surface of the brake disc look smooth, but the brake pads will also rattle if they are installed on the brake discs rubbed by the small brake pads. In such a situation, you need to pick up the disc first, if you don't have the disc can drive for a period of time, and the trace will not sound after the trace.

With the increase of service life, it is difficult to avoid some minor problems in the car, such as abnormal noise of the car brake disc. So how to solve the abnormal noise of the automobile brake disc?

If there is an abnormal sound because there are some foreign objects between the brake disc and the brake pads, such as small stone chips mixed with fine stones, in this case, just remove the small gravel between them.

If the brake pads or brake discs are worn too badly and the brake noise is too serious, it is recommended to go to a professional auto repair shop for repair in time.

If the brake pads and brake discs of the car have abnormal brake noise due to quality problems, this situation needs to be replaced with new brake pads or brake discs in time.

If the brake pads make a rattling noise, check whether the accessories on the brake pads are loose, and if they are loose, re-strengthen or replace the brake pads with new ones.

If the brake pads are muffled, it is recommended that the driver immediately check the brake calipers to check the wear of the brake caliper removable pins, check whether the springs are falling off, and replace them immediately if so.

The above is all the content brought to you about how to solve the abnormal noise of automobile brake discs.

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.

There are many reasons why brake discs can be noisy, including the following common situations:

1.Abnormal noise caused by deformation of the brake disc. 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 discs are badly 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.Foreign objects between the brake pads and brake discs are common. There may be foreign objects such as pebbles or water films, which can cause abnormal noise. Generally, after driving for a period of time, the abnormal noise will slowly disappear, or you can remove the foreign object by yourself.

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

5.The brake discs of the car are somewhat rusty. This is very easy to happen 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 of the collapsed hail can be wiped off.

6. During the run-in period of the new car or just after changing the brake pads, there will be a certain abnormal noise, which is a normal phenomenon, and the abnormal sound will disappear after running-in or holding.

Millions of car purchase subsidies.

First of all, if you notice that the wheels or brakes are making abnormal noises while driving, you should find an opportunity to pull over and check whether there are foreign objects sticking to the wheels. If there is an abnormal sound of the wheels, there is generally a debris, if there is an abnormal sound of the brakes, there may be the following multiple situations, which can be eliminated one by one.

First, it may be that your car has not been driven for a long time, the brake pads are rusty, and there is an abnormal sound in the brakes just now. You can solve this problem yourself.

Second, if it is a very sharp sound, and there is still a distance after driving, it may be that the brake pads have worn out badly, and the brake pads are almost worn out, so it is recommended to check and replace them.

Third, check whether there is any foreign object running between the brake discs, and if so, clean up some oil, and the sound disappears.

Fourth, after the above situations are ruled out, it is also possible that the caliper is not reset in time, resulting in long-term friction of the disc, and the sound will be very loud.

In short, the brake has abnormal noise, it is necessary to attach great importance to it, it is recommended that you can drive to the 4S shop for maintenance every time you maintain it, because although it is expensive to drive to 4S, it is generally checked more comprehensively, and there is a good point to check the brakes for free, only the money for working hours and oil and three filters.

I believe that many car owners and friends have encountered the situation of abnormal brake noise. However, if there is an abnormal noise when braking, does it mean that the brake system is malfunctioning? Not really. In the following cases, abnormal brake noise is a normal phenomenon, and you don't need to worry too much.

1.There is a "hissing" sound when the brakes of the new car.

When the new car is in the run-in period, the brake discs and friction pads are new, and they have not yet reached a relatively consistent state with the brake shoes. At this time, it is normal to have a "hissing" sound, and it will be automatically eliminated after a period of running-in.

2.There is a "pop" sound when braking suddenly.

When braking suddenly, the brake pedal will have a continuous "boom" sound, and sometimes there will be a phenomenon of springing feet, which means that the ABS system is starting, which is a normal sound, and at this time, you can vigorously press the brake pedal to the end.

3.There is a "whine" sound in a humid environment.

When the vehicle is in a wet environment (such as on a rainy day or when washing a car), there will be residual water on the brake discs, in which case there may be a "whine" sound when braking at low speeds, which will automatically disappear when the water evaporates.

4.There is a "boom" sound when the cold car starts.

If the vehicle is stored in a humid environment for a long time, rust will form on the surface of the brake disc and brake pads, and it will make a "boom" noise when the vehicle is started. In fact, this is caused by the brake disc and brake pads sticking together due to rust, and it is generally good to step on the brakes a few times after hitting the road to wear off the rust on the brake disc.
