The brake pads of the car start to be installed very well, why the noise in the later stage?
A: Based on the brake pads and brake discs are a pair of friction pairs, so it is recommended that the brake pads compare the performance of the brake pads after using 300~500 kilometers, because at this time, the brake pads and discs are basically running-in. Noise generated during this time period is sometimes not the cause of the brake pads. If there is noise after a long time of use, it is necessary to judge the problem of brake pads.
Now a lot of online sell brake pads, how about the quality?
A: I don’t know. We can’t judge it in real life, and there’s no way to judge it online. What can be judged is the feedback of the use effect after your installation, you can choose an unmanned road section, and test several emergency braking at higher speeds and emergency braking in rainy days, although it costs a little oil. However, it is of great benefit to you to judge the braking stability of the product in emergency situations.
It feels that the metal content is hard, and the hard must be noisy, which is what the garage said, right?
A: No. Many of these statements are those of the auto repair factory and are not scientific. The original car in the United States is mainly semi-metal formula, which contains a lot of metal, have you heard a lot of noise? Noise is not directly related to hardness, grinding disc and noise only indicate that the product formula is immature, and how much metal has nothing to do with it. In fact, metal materials in the formula mainly play the role of connecting fillers and heat conduction, at the same time, their own hardness and disk are not very different, will not cause large wear on the disk, the real disk and increase the braking ability is not you see these metals, but you can not see those hardness is harder than the brake disc grinding agent filler, they are actually emery, And your common sandpaper, grinding wheel belongs to the same material.
