The steps to replace car brake pads are: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located; 3. Remove the bolts of the brake caliper and take out the brake pads; 4. Install new brake pads and tighten the guide bolts. The working principle of brake pads is to use the friction between the brake pads and the brake drum, as well as between the tires and the ground, to convert the kinetic energy of the vehicle into heat energy through friction, thereby stopping the vehicle. The materials used for brake pads are: 1. Asbestos, cellulose, sintered glass; 2. Carbon fiber friction materials; 3. Powder metallurgy friction materials; 4. Semi-metallic friction materials.
