X Trail asks everyone what is the sound of the brakes The turning is especially obvious, and you can

Hello, it is possible that there are hard spots between the brake pads and the disc, grinding or replacing new parts.

1. If it is screaming, the first thing to check is to despise the brake pads that are running out (the alarm pads sound). If it is a new film, then check whether there is any foreign object caught between the brake disc and the plate.

2. If it is muffled, it is mostly a problem with the brake caliper, such as the wear of the movable pin, the fall off of the spring blade, etc.

3. If it is called, then there are more problems, such as calipers, brake discs, and brake pads.

If the sound is continuous, first check whether there is drag, poor caliper reset will cause the disc to rub against the disc for a long time, and under certain conditions, it will make abnormal noise. Then check whether there is any foreign object stuck between the disc and the disc. If it is a new film, it depends on whether the brake disc is grooved, because local friction will cause abnormal noise.

If there is no problem with the disc, then consider whether the brake pads are too stiff or the muffler is installed incorrectly.

The most common reason for the rattling of the brakes is that the brake pads are worn thin, and the brake drum is in direct contact with the vehicle, and the friction between the metals must be loud. If the brake pad is thin, the warning indicator should be on, but sometimes it will not be lit until the set limit. If there is no problem with the brake pad after checking, then drive normally, and replace it in time if there is a problem.

Brakes sizzle! Sometimes it can be because the brake pads are thin! It's time to replace the brake pads! It is advisable to find a place to repair the car.

What's going on with the sizzle of car brakes.

If the sound is more harsh, it should be that the brake pads have reached the grinding limit, you can go to the 4S shop maintenance shop to check the brake pads, if the thickness of the brake pads is appropriate, you can use sandpaper to polish it, which can generally solve the problem, I hope it will help you.

The first reason: the brake pads of the new car can also cause abnormal noises during the run-in period, why is this? The main reason is that the friction surfaces between them have not yet reached a complete match, so each brake is a process of mutual torture and testing, which will cause abnormal brake pad noise.

The second reason: the brake pads are too hard, although many car manufacturers now use some semi-metallic materials to make brake pads when they are produced, but affected by the process, the third reason: the brake caliper is out of order, so how to know that the brake caliper is faulty?

After the brake caliper fails, the hand slag brake will make a quiet and muffled sound, and the owner needs to pay attention to it when he hears this sound.

1. There is sand in the brake disc. Under normal circumstances, the new car we just bought is not a chain when stepping on the brakes, it will make an abnormal sound, if your DAO car has not run many kilometers and the brakes will make abnormal noises, most likely because the brakes have entered the sand or iron powder and other particles, at this time, as long as you step on the brakes, it will make a screeching sound. In this case, we can use a high-pressure water gun to flush it when washing the car, and if it doesn't work, we have to disassemble and clean it.

If you don't leave it alone, it will accelerate the wear of the brake pads, and in severe cases, it may even damage the brake discs.

2. The brake pads are too hard. Some new cars that have just bought have abnormal noises when they brake, especially when they step on the brakes lightly, which is generally because the material of the brake pads is relatively hard, and there is no abnormal sound when the brakes are stepped on heavily. Generally, we can ignore this situation, wait for it to run in for a while and then see, if you really can't stand this sound, go to change a pair of brake pads can solve the problem.

3. The brake pads are seriously worn. Some time ago, a friend of mine told me that his car has been making a "squeaking" sound when he has been on the brakes in recent months, and he doesn't know what's going on, so he wanted to ask me. He has been driving this car for 4 years, and I asked him if he had changed the brake pads, and he actually asked me if the brake pads still need to be changed?

I was completely speechless at this point. Hurry up to the repair shop to check, the brake pads are worn out, the brakes are iron to iron, and even the brake disc is scratched, which is a heavy loss.

The above are the 3 reasons for the abnormal sound of the car stepping on the brakes summarized by the old car repair driver, the first two are normal, and the last one hurts the car the most! If your car has an abnormal sound when it hits the brakes, check the brake pads quickly! In most cases, the abnormal sound of stepping on the brakes is the sound of the brake pads reaching the lower limit of wear and tear and the alarm iron plates, and we only need to replace the brake pads at this time.

The solution to X-Trail brake squeak is as follows:

1. If it is a screaming sound, the first thing to check is whether the liquid is running out or the brake pads are running out (the alarm pads are sounding). If it is a new number of pieces, then check whether there are any foreign objects caught between the brake disc and the plate;

2. If it is a muffled sound, it is mostly a problem with the brake caliper, such as the wear of the movable pin, the fall off of the spring blade, etc.;

3. If it is the sound of Bihu, it is more troublesome, and there is a problem with the matching of calipers, brake discs and brake pads, which needs to be checked one by one.

The causes and solutions of X-Trail brake abnormal noise are the sound of brake pad alarm drawing, the presence of foreign objects between the brake pad and the brake disc, and the gap between the brake pad and the brake disc is too small. If the brake pad has an abnormal noise, you need to clean up the foreign object or adjust the gap between the brake pad and the brake disc.

Here's how to replace the brake pads:

1. Before replacing the brake pads, you should first open the lid of the brake fluid reservoir in the engine compartment to see the height of the brake fluid page, if the brake fluid page is above the highest level, the brake fluid should be sucked out to prevent the brake fluid from overflowing during the replacement process;

2. Prepare the brake pads to be replaced and remove the wheels where the brakes are located. In the process of dismantling, it is necessary to avoid scratches on the rim;

3. Use a wrench combined with Wang Hui's socket to remove the bolts of the brake caliper, and then remove the brake pad (if there is a brake induction line, the brake induction line should be removed first). Observe whether the brake pads are overworn, or cracked, and replace them in the next step;

4. Because the brake caliper will be very peiling and sand or mud, it should be cleaned with a rag, and then apply silencer paste to prevent abnormal noise when braking;

5. Press the piston to the position where the piston pressure pump cannot be pressed, then install the brake pads on the brake caliper, install the new brake pads in place (those with brake induction lines should also be installed), tighten the guide bolts, and the installation is completed;

6. After installation, cover the lid of the liquid storage tank, enter the car and press the brake pedal a few times, and reset the brake. Then observe the height of the brake fluid, which should be within the appropriate height range;

7. Test drive after changing to check whether the braking effect is reflected.

What is the cause of X-Trail brake noiseWhat is the cause of X-Trail brake noise There are many reasons for the abnormal noise of automobile brake pads, but the overall summary is mainly these, which are caused by the run-in period of the new car, the brake pads are too hard, the brake pads have been seriously worn, and the brake calipers are caused. The following is the solution to the problem of X-Trail brake noise: 1. If it is the sound made by the gearbox, the gearbox needs to be overhauled; 2. If it is a problem of ABS, it needs to be solved by computer detection and code reading; 3. If the abnormal noise is made by the brake caliper, it is easy to deal with.

To determine the type of sound, if it is a scream, the first thing to check is whether the brake pads are running out (the alarm pads are sounding). If it is a new film, check to see if there is any foreign object caught between the brake disc and the plate. If it is muffled, it is mostly a problem with the brake caliper, such as the wear of the movable pin, the fall off of the spring blade, etc.

If it is called, it will be more troublesome, and there may be problems with calipers, brake discs, and brake pads, which need to be checked one by one. @2019

The reasons for the abnormal noise of the X-Trail brake cluster stool car are as follows:

1. If the brake pads are about to run out (the alarm pads make a sound) or a foreign object is clamped between the brake disc and the pads, Youzhi will scream;

2. If it is a problem with the brake caliper, there will be a muffled sound if the movable pin is worn and the spring blade falls off.

3. If it is a caliper, brake disc, brake pad has problems, such as the quality of parts, parts matching, etc., there will be a slight sound, which needs to be checked one by one.
