Analysis of the real causes of brake pad injury

Brake pads in the use of the process will produce a lot of problems, brake pads are caused by many factors, these you know?
Several reasons for brake pad nibbling disc:
Raw material problems: the mineral fiber slag ball in the brake pad will scratch the brake disc, and the slag ball in the mineral fiber is more likely to produce noise.
The material that is easy to scratch the disc in the raw material is artificial graphite, the hardness of artificial graphite itself is very soft, and the impurity silicon carbide hardness inside is close to diamond, enough to scratch the brake disc. Brake pads with artificial graphite, most of the small factory is the use of recycled waste graphite (in the big brand products will never use recycled graphite), some industries have no effect on the graphite containing silicon carbide, but the use of brake pads, silicon carbide has become a very harmful substance.
Brake pad raw materials will have problems in the same batch should have problems, may involve a wide range of surfaces. In this situation, the brake pads must be replaced in time, and if the brake discs are seriously damaged, the brake discs will have to be replaced. This situation is generally symmetrical two brake disc four friction surfaces at the same time gnawing conditions, and the position of the slot irregular, may be high or low, may also be all slots.
The brake pad attachment also grooves the brake pad. Some brake pads have alarm pads (alarm pads are generally made of stainless steel), when the brake pads are worn to the alarm pad position, the brake alarm will produce friction with the brake disc, and emit a harsh scream to prompt the owner to change the brake pad. If the owner does not pay attention to the sound, let the alarm and brake pads grind, the brake disc will be scratched. This kind of pit will generally only appear a slot, not serious direct change of the brake pads can occur, this situation, the general position of the brake disc slot is fixed, is the position of contact with the alarm sheet.
