Brake pad life

What's the matter with the short life of the brake pads? Why do inferior products have long braking distances in emergency braking situations?

Answer: Like all objects, the strength of intermolecular links in the material organization decreases at high temperatures. The principle of braking is to convert kinetic energy into heat energy in the form of friction to achieve braking (energy balance theory). Therefore, a large amount of heat generated by the friction between the brake pad and the disc will accumulate on the surface of the friction material of the brake pad. In order to maintain sufficient strength of the brake pads under such high temperature conditions, materials such as high-temperature resin, high-purity graphite, and high-purity barium sulfate must be selected.

For inferior brake pads, they will not use such high-end materials, so they cannot guarantee stability at high temperatures, and as the speed increases, the heat will be more, the temperature will be higher, and the link strength will be lower, thereby reducing the brake pads. Dynamic ability, manifested as extended braking distance. Therefore, the brake pads that you feel comfortable driving at a speed of 20 to 60 kilometers per hour in the city do not mean that you have the same stable braking distance performance at high speeds. When the link strength of the molecular chain is reduced at high temperature, its wear and tear is accelerated, which is why the service life of general brand brake pads is very short in mountainous areas or in the state of frequent sudden braking.
