What If The Brake Pads Have Abnormal Noise?

The problem of abnormal brakes has been encountered by many friends during the driving process. And sometimes there is no, go to the repair shop check will often tell that there is no problem. But it didn't take long before the sound appeared again and there seemed to be no rules at all. In the end, where did this sound come from, and what caused it? Today, Ford USA Brake Pad manufacturers come to analyze and analyze.

When it comes to brake pads, you have to mention the brakes on these four wheels. At present, it is divided into two types: disc brakes and drum brakes. The disc brakes are also called disc brakes. The brake discs are clamped by brake calipers, and the friction is provided by the friction between the calipers and the brake pads. The drum brake is applied by the brake booster pump to rub the brake pad in the drum brake with the drum wall to generate the braking force. After talking about the types of brakes, let’s talk about today’s theme. Why is there always an abnormal noise? Take the current mainstream Disc Brake Pads on the market, the disc brakes just mentioned have better heat dissipation, but the sacrifice is due to the tightness, because sand particles are always attached to the brake pads in daily driving. When braking, the brake disc and the brake pad rub against each other, and there is a certain sound due to the incorporation of impurities between the two, which usually does not last long.

At present, most of the brake pads are made of semi-metal or a small amount of metal materials. Due to the influence of production process and quality control, some hard spots or metal particles may be generated in the brake pads. When the vehicle is braked, due to the presence of these metal particles, the brake pads produce a sharp sound when rubbed against the brake disc. As the vehicle's usage time changes, it will create a circle of scratches on the brake pads and will increase the wear of the brake pads.

As the wear-loss piece, the brake pad forms a circle of protrusions at a position where the outer brake does not rub around. If the brake disc is rubbed against the outer protruding portion of the ring during braking, an abnormal noise will inevitably occur. At this point, you can choose to polish the brake pads or replace them with new ones. The reason why a bump is generated on the periphery of the brake pad is because the brake disc is the same as the brake pad. Since the brake disc is usually worn slower than the brake pad, it still has a certain loss. Therefore, a circle where the brake disc is not rubbed is formed on the periphery of the brake pad.

In addition, it is also possible to judge whether there is a problem with the brake pad based on the sound generated when braking. If there is a short, sharp sound during braking and multiple occurrences in a short period of time, it may be because the brake pads have metal particles. If this situation has already been opened for tens of thousands of kilometers, it means that the thickness of the brake pad may have reached the limit, and a new brake pad needs to be replaced. There is also a case where other noises appear in the vicinity of the brake pad when the brake generates an abnormal sound, which may be caused by the looseness of the brake disc caliper, and the specific reason needs to be confirmed by the repair shop.

The above is a description of the reasons why the brake pads make a sound by Hummer Brake Pad Manufacturer. In addition to the above, there may be abnormal sounds due to other reasons. All in all, if the abnormal sound duration is not long and there are no other noises, you can basically ignore it. Also, often slamming the brakes will also reduce the life of the brake pads to a certain extent, thereby increasing the chance of abnormal noise. Therefore, it is very necessary to develop good car habits and do regular inspections of the brake system.
