Brake Pad Frequently Asked Questions Encyclopedia Worth Collection (3)
16. As long as there is no noise from the brake pads, isn’t it enough to stop the car? Is it that mysterious?
Answer: As mentioned above, it is very simple to solve the noise alone. But the main function of brake pads is not noise, but safety. Now the market really pays too much attention to the noise and ignores the main function of the brake pads. As for what everyone said, is it enough to stop the car? That's right, just stop the car, but you may not have thought that you can stop the car on flat roads, you can stop the car at normal speeds, but can you stop the car in emergency braking situations? Can you stop the car under the high temperature of continuous braking on the winding mountain road? Can you guarantee the braking distance at a speed of 100 kilometers per hour on a rainy day? What the original car brake pads must guarantee is the stability of the braking ability when we need safety most. At this point, I believe that many car owners who think that braking is enough have never thought about it. If it is all right, why can only a small number of the more than 600 manufacturers in China that have obtained brake pad production licenses enter the original car factory? The reason is here. Of course, it doesn’t mean that non-original cars cannot be guaranteed, it just means that original cars are more sure, because there is no third-party supervision like automobile factories, and the desire of Chinese people to reduce costs is great.
17. The brake pads are installed very well at the beginning, but why is there noise in the later stage?
Answer: Since the brake pads and brake discs are a pair of frictional couples, it is recommended to compare the performance of the brake pads after the brake pads have been used for 300-500 kilometers, because at this time, the brake pads and the discs 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.
18. Where can I buy brake pads of the original car quality?
Answer: Try to choose those professional brake pad companies with original car matching capabilities. Although their own after-sales brands do not carry the trademark of the automobile factory, their quality is not inferior to that of 4S shops. It would be even better if you can guarantee a service life of 70,000 kilometers and 80,000 kilometers. Because the price difference between the original car brake pads and high-imitation brake pads on the market is not more than 100 yuan, but this value brings a completely different security guarantee.
19. I have seen a lot of yellow brake pads. Is it true that the more copper the better?
Answer: No. Whether it is brass or copper, copper powder or copper fiber. They are all one of several fillers for brake pads, and their main function is to increase the connection strength and heat conduction. The pollution of copper to the environment is serious, so, like the United States, legislation has begun to prohibit the use of copper in brake pads. Therefore, it is wrong to judge the quality of brake pads by the amount of copper content. Furthermore, it is not certain whether the yellow surface you see is copper. There is a kind of golden yellow filler called vermiculite, which is very cheap and is often used in brake pads.
20. How long can the brake disc generally be used?
Answer: In theory, 3 sets of brake pads need to be replaced with a set of brake discs, and the service life is about 150,000 to 200,000 kilometers. If the brake pads you use are mostly low-metal formula or some low-quality brake pads, the service life of the disc will be greatly reduced, about 10-15 kilometers is not bad. Of course, if you have been using pure ceramic formula, congratulations, your brake discs do not need to be replaced within 250,000 to 300,000 kilometers.
