The important role of friction material in brake pads (below)
2. Insulation layer
During the braking process of the vehicle, due to the high-speed friction between the brake pad and the brake disc, a large amount of heat is generated instantaneously. If the heat is directly transferred to the metal back plate of the brake pad, it will cause the brake cylinder to overheat, and in severe cases may cause The dynamic fluid creates air resistance. Therefore, there is a layer of thermal insulation between the friction material and the metal back plate. After the brake pads are ablated by high temperature and high pressure, the running-in period between the new brake pads and the original brake discs will be shortened, and the high temperature of the brakes can be effectively isolated, so as to maintain a stable braking safety distance and braking comfort.
3. One-time hot pressing
The brake pad adopts one-time molding hot pressing technology to ensure the stability of the product's hardness, density and other indicators. The safety factor is higher, and the safety of car owners is always protected.
4. Backplane
The role of the back plate is to support the overall structure of the friction material, and transmit the braking force of the brake cylinder, so that the friction material of the brake pad and the brake disc are efficiently bonded. The back plate of the brake pad has the following characteristics:
a. meet stringent durability specifications;
b. Ensure the safe operation of friction materials and brake calipers;
c. With a layer of high-quality environmental protection coating;
d. Environmentally friendly and anti-rust, durable to use.
5. Silencer
The imported sound-absorbing sheet is selected on the back plate, and it is coated with a layer of absorbing coating, which is used to suppress vibration noise and improve braking comfort.
