When you step on the brake, most people will make a strange noise, because the brake pads will certainly make a sound when they are worn to the limit. Usually, when you step on the brake gently, you will hear a squeak, but if you step on the brake very tightly, you may not make a sound. When you step on the brake, even if you don't step on the brake, you will also hear a creak. Today, let's talk about the strange sound when you step on the brake, Is it time to replace the brake pads?

The abnormal brake noise has nothing to do with the brake disc, but is caused by the abnormal brake pad. If you hear the abnormal sound, please check the thickness of the brake pad, which is the standard to ensure safety. Why does the brake pad make strange noise even if it is very thin? This is designed on purpose. When the thickness of the brake pad is normal, the small iron plate is a certain distance away from the brake disc, and there is no friction between the two. When the brake pad is worn to the limit, a small piece of iron plate touches the brake disc and makes a harsh noise between the iron plate and the iron plate. The driver is urged to replace the brake pad immediately. Therefore, if you hear the noise, please Check the brake pads in time. The small iron plates of many cars have been worn, and there is no sound for a period of time. If you continue to use the brake pads, the brake pads will wear and the brake discs will also wear. Therefore, those who do not make a sound for several days should not think that they are back to normal. As long as the brake rings, you must check the thickness

After the alarm, the thickness of the brake pad is about 2mm, even if driving for hundreds of kilometers, there is no problem, so don't be too nervous. Please don't open it, and replace it immediately when you have time. Pay attention to check the brake pad and carefully check the left and right sides. If you can't see clearly, it's better to remove the tire for inspection, because the wear degree of the left and right sides may be different, or even the two brakes on the same side There are also differences in the degree of wear.

The brake pad is not thin, and it may make a noise when braking. This is because the brake pad has large metal particles, and the friction noise with the brake disc is also the friction noise between iron and iron. This is a normal phenomenon. The quality of the brake pads is no problem. This happens to the brake pads of many original cars. If you want to eliminate the abnormal noise, you can only remove the brake pads and grind them Sandpaper grinds off a layer of the brake pad, and the metal particles leaked out will not make a sound. In fact, you can ignore it. After a period of time, it will wear off, and the abnormal noise will disappear, and there will be no damage to the brake disc.

If the brake disc is very thin, there is no abnormal sound, and there is no other alarm device. Only the usual inspection can determine whether it needs to be replaced. Generally, after the wear depth of the brake disc reaches 2mm, it is usually necessary to replace the brake disc. How to know how much it has been worn? Because it is not necessary to compare with the new brake disc, the outermost end of the brake disc has been worn, and the installation position of the brake pad cannot reach the outermost end of the brake disc. Therefore, the wear depth of the brake disc starts from the outer edge, that is, the height difference between the worn place and the non worn place is the wear depth. Generally, it is necessary to replace the brake disc once or twice to replace the brake pad
