What material is the brake pad made of? Is it better for metal brake pads or ceramics?

Brake pads are one of the most important parts in a car's braking system. The brake pads play a decisive role in the effectiveness of the car's braking. A brake pad with superior performance can provide better protection for daily driving. Brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. The materials are mainly made of metal, NAO, carbon and ceramic materials, as well as asbestos materials, but they have basically been eliminated.

Among them, metal brake pads can be divided into less metal brake pads and semi-metal brake pads. Semi-metallic brake pads have good heat resistance, high absorption power per unit area, and large thermal conductivity, which can be applied to the braking conditions of automobiles at high speeds and heavy loads. It is a very common type of brake pad that is more used in ordinary cars, but it has the disadvantages of large braking noise and brittle corners. The performance of less metal materials will be higher than that of half metal. In mid-range cars.

Compared with metal brake pads, ceramic ones are better. Ceramic materials are harder and more wear-resistant. Real ceramic brake pads contain aramid fibers and do not contain metal. They have good thermal stability, low thermal conductivity and good wear resistance, which can meet various high-performance systems. The high-performance requirements of dynamic materials can also meet the technical requirements of brake pads for high-speed, safety, and high wear resistance, and are more used in high-performance sports cars.
