There are many kinds of materials for bicycle
brake pads, and the most common ones are steel and titanium alloys. The better ones are ceramic ones, but these brake pads are expensive.
1. Asbestos brake pads
Asbestos fiber has the characteristics of high strength and high temperature resistance, which can meet the requirements of brake pads and clutch discs and pads. The tensile strength of asbestos fibers can even match that of high-grade steel, and can withstand high temperatures of 316°C.
2. Semi-metal car brake pads
These brake pads use coarse steel wool as a reinforcing fiber and an important compound. Steel wool has high strength, thermal conductivity, strong temperature control ability and good high temperature resistance. In general, the basic requirements for brake pads are wear resistance, high friction coefficient, and excellent thermal insulation properties.
The wear resistance, friction coefficient and thermal insulation performance of steel brake pads are average, but the material source is wide and the price is low. Generally, steel materials are used without special requirements.
The above three properties of alloy brake pads are much better than those of steel materials, but since alloys need to be processed and processed on ordinary metal materials, the cost is high and the price is relatively high.
Ceramic brake pads need to go through more stringent production and material selection. Although the above three performances are good, they are expensive and generally not used.
Disc brake pads are used in disc brakes. Disc brakes are composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake fluid pushes the brake pads to clamp the brake disc to produce a braking effect.
