What materials are used for bicycle brake pads?
1. Asbestos type brake pads
Asbestos fiber has the characteristics of high strength and high-temperature resistance, which can meet the requirements of brake pads, clutch discs, and gaskets. The tensile strength of asbestos fiber can even match that of high-grade steel, and it can withstand a high temperature of 316°C.
2. Semi-metallic car brake pads
This type of brake friction pad uses rough steel wool as a reinforcing fiber and an important mixture. Steel wool has high strength, thermal conductivity, strong temperature control ability, and high-temperature resistance.
Classification of bicycle brake pads
1. Wire pull disc brake
The tension of the wire drives the brake pads in the caliper to rub against the disc, thereby producing a braking effect.
2. Hydraulic disc brake
The oil is mainly used as the transmission material, and the piston compresses the oil to push the brake pads to rub against the disc, thereby producing a braking effect. This kind of brake has very strict requirements for sealing, so as to ensure the minimum loss of transmission force, so the brake force of hydraulic disc brakes is stronger.
3. V brake
The brake pads and the rim are driven to generate friction through the wire pulling method, so as to achieve the braking effect. The advantages are lightweight, simple structure, and the price is relatively affordable and does not require excessive maintenance.
