What should I do if the brakes are abnormal? Hyundai Langdong has a sound when he steps on the brake

Possible scenarios and treatments:1If it's a scream, the first thing to check is that the brake pads are running out (the alarm pads are sounding).

2.If it is a new brake pad, see if the brake disc is grooved, because local friction will cause abnormal noise. If there is no problem with the brake disc, consider whether the brake pads are too hard, or the muffler is installed incorrectly, and check whether there is any foreign object caught between the brake disc and the brake pad pads.

3.If it is muffled, there may be a problem with the brake caliper, such as worn movable pins, spring blades falling off, etc. 4.

If it is the slightest sound, then there are more problems, calipers, brake discs, brake pads may have problems. 5.If the sound is continuous, check whether there is a drag brake, poor return of the brake caliper will cause the brake disc and the brake pad to rub for a long time, and under certain conditions, it will make abnormal noise.

If there is an abnormal noise, there may be the following reasons: 1. The hardness of the brake disc is different during manufacturing, resulting in different degrees of wear, which will not have much impact. If the sound you hear is in the cab (at the brake pedal), it may be due to the wearing of the nylon bushing on the brake pedal fixing bracket and the sound of the brake pedal fixing pin rubbing against him.

2. The wear of the disc is very serious, and there is a direct contact with the iron parts. How to solve the problem: (1) If it is the cause of the hard point, the easiest way is to step on the hard point when the speed of the sports car is about 5 kilometers backwards, and you can generally remove the hard point.

The sound is not too loud, it is recommended or ignored, and it has no effect on driving. (2) If it is iron-to-iron, the disc should be replaced immediately. In addition, at this time, the brake of the instrument does not alarm, and the sensor connected to the brake fault light should be checked at the same time.

Modern brakes are noisy. 1.The run-in of the new car is stupid, in which the run-in of the brake pads is a very important link, usually after running for hundreds of kilometers, can you feel that the brakes will be more comfortable;

2.The new brake pads also need to be run in to better combine with the old ones. When you first change it, you will feel that the brakes are very hard, and it usually takes hundreds of kilometers to feel better.

3.During the driving of the vehicle, small sand particles may enter the middle of the plate and plate, and sometimes abnormal noise will be produced due to friction. In this case, maintenance is generally not required. Just run and let the little grains of sand fall out.

4.If there is abnormal noise because of poor running-in, some car owners simply run over and brake sharply, so that they can drive in the brakes in a short time, but this will make the brake pads more worn, that is, it will reduce the service life of the brake pads. Therefore, it is recommended that you run for a while, observe, and do not artificially force the brake pads to wear;

5.Loss or damage to the brake disc fixing screw can also cause abnormal braking noise;

6.The braking system is faulty and needs to be inspected and maintained.

1. The run-in of the new car, in which the run-in of the brake pads is a very important link, and the pickpockets usually run hundreds of kilometers before they 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 piece and the plate, and sometimes there will be abnormal noise due to friction, which usually does not need to be maintained, and the small sand particles can fall out by running. <

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 a strange sound due to friction, which usually does not need to be repaired, and the small sand particles can fall out by running.

4. For those who do not run in well and have abnormal noises, run for a period of time to observe, and do not artificially force the brake pads to be worn;

5. If the fixing screw of the brake disc is lost or damaged, it will also cause abnormal brake noise;

6. The brake system is faulty, which needs to be inspected and repaired.

Summary. If you feel that it is under the chassis outside the car, you need to check the ball head of the lower arm, as well as the rubber sleeve, to see if there is any looseness, and you need to check the brake pads, and see if there is a large gap in the brake pump, which needs to be checked. If it feels like this sound appears under the steering wheel and near the brake pedal, this is the sound that occurs when the brake control switch presses the brake, this is a normal phenomenon and there is not much of a problem.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

If you feel that it is under the chassis outside the car, you need to check the ball head of the lower arm, as well as the rubber sleeve, to see if there is any looseness, and you need to check the brake pads, and see if there is a large gap in the brake wind pump, which needs to be checked. If it feels like this sound is under the steering wheel, and the position near the brake pedal appears This is the sound that occurs when the brake control bucket core switch steps on the brake, this is a normal phenomenon, and there is no problem of long and short coarseness.

What is the reason for the abnormal start and brake noise of Volkswagen Langxing, which is caused by too many brake pads. Check that the brake pads are not worn to the limit. If not, this phenomenon is normal.

This happens in all Volkswagen cars, and it has to do with the material, so it's hard and easy to rattle, but it's durable. If the brakes are not normal, the brake pads are thicker, and you can brake the car several times. This situation is mainly caused by the excellent material of the brake pads and too many impurities.

It can be removed and polished to ensure that the joint surface is smooth and normal, reduce the wear of the brake disc, and eliminate abnormal noise. Timely maintenance can ensure driving stability, comfort and safety. If it's screaming, the first thing to check is contempt.

The brake pads are running out. If it is new, check the brake disc for foreign objects between the brake disc and the brake disc. If it is a muffled sound, it is most likely the degree of brake calipers, such as the wear of the movable pin, the fall off of the spring blades, etc.

If it's a squeaky sound, it's more of a problem, it could be a problem with the caliper opening, the brake disc, the brake pads. If the noise persists, first check if there is braking resistance. Poor caliper reset will cause the brake disc to rub against the brake disc for a long time, and under certain conditions, it will emit abnormal noise.

Then check the disc for foreign objects between the disc and the disc. If it is a new part, it is necessary to see if the brake disc has grooves, because local friction will produce abnormal noise. If there is no problem with the brake disc, you should consider whether the brake pads are too stiff or if the silencer is installed incorrectly.

If the pants only sound when the brakes are bored, it means that the brake pads are too hard. In summary, braking is done by means of curved calipers, brake pads, and brake discs, all of which can produce unusual noise. But people often blame the brake pads.
