1.Car brake pads are - an important brake system component used to catch the wheels and slow down the speed. Explanation:Automotive brake pads are one of the core components of a vehicle's braking system, which converts the vehicle's kinetic energy into heat, thereby slowing or stopping the vehicle's movement.

2. Brake pads are divided into organometallic brake pads and semi-metallic brake pads.

Explanation:Organometallic brake pads are composed of organic materials and metal powder, they not only have very good braking effect and low storage power, and relatively cheap. Semi-metallic brake pads are made of semi-metallic materials, which are more reliable and efficient than organometallic brake pads.

3.Brake pads consist of friction material, support plate and bolts.

4. The material of the brake pad is inseparable from the friction performance.

5. Brake pad friction material contains copper, iron, graphite, silicon carbide and other components.
