Brake Pad Frequently Asked Questions Encyclopedia (Medium)
Is it because the brake pads have no noise, but are soft, and their service life is short?
Answer: No, many of these claims come from auto repair shops. There is noise, say the brake pads are hard, I will give you a soft one, there is no noise, but you are required to accept the defect of short life. If you want to have a long life like a taxi, it must be hard, you can only accept noise or grinding discs. In fact, these statements are not accurate. In addition to the mature formula of the original car, it has the ability to ensure low noise and long life. Most of the products on the market are solely taking noise as the main goal, and they are for the so-called market demand. These products basically have a very short lifespan, about 20,000 to 40,000 kilometers. As for whether it can guarantee the safe braking distance of the owner in an emergency and the braking ability under high temperature. That needs to be judged by the owner.
What's the matter with some brake pads that feel shaking when stepping on the brakes? Just change to another pair. Is it because of the quality of the brake pads?
Brake pads do not cause judder. The reason for the vibration is mostly because the brake disc is deformed by alternating hot and cold under high temperature conditions or the brake disc is warped after re-disc processing, which has nothing to do with the brake pads. As for why you just changed it, it is estimated that the reason is that the latter is very compressive, and the product can absorb the warping and deformation of the brake disc. In the supporting standard of the original car, compressibility is a very important item, which requires the compressibility of the brake pads to be between 0.1 and 0.2 mm under normal braking force, so as to ensure the response of the brake pads under emergency braking conditions. speed. Therefore, based on the above considerations, if it is enough to replace the brake pads because of vibration, you may not be happy.
The brake pads are installed very well at the beginning, why is there noise in the later stage?
Since the brake pad and the brake disc are a frictional pair, it is recommended to compare the performance of the brake pad after the brake pad has been used for 300-500 kilometers, because at this time, the brake pad and the disc are basically run-in. The noise produced during this time period is sometimes not the cause of the brake pads. And if there is noise after a long period of use, it is necessary to judge the problem of the brake pads.
