The Ceramic formula does not refer to a formula using ceramic fibers. The standard for judging whether a formula is ceramic is mainly the performance of the material, but this material refers not to the raw materials used, but the performance of the finished product.
Low metal brake pads rattling may be due to the brake pads become thin backplate grinding brake discs, low metal brake pads in the foreign body will lead to the case of rattling, so when the brake rattling first check the thickness of the low metal brake pads, the thickness of the problem without a few feet of brake may ease the problem of rattling. Here is an introduction to the causes of low metal brake pad rattling.
Semi-metal-based friction materials are very stable below the conflict coefficient, without thermal degradation, and have good thermal stability. Semi-metal-based friction material has good wear resistance, and its service life is 3-5 times that of asbestos friction material; it has good conflict performance and stable conflict coefficient under high load.
