Do the brake pads on both front and rear wheels of the car need to be replaced?
1 Answers
Both the front and rear brake pads of the vehicle need to be replaced. The replacement method is as follows: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake pad is located; 3. Remove the bolts of the brake caliper and take out the brake pad; 4. Install the new brake pad, tighten the guide bolts, and complete the replacement. The working principle of brake pads is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby stopping the vehicle. The materials of brake pads include: 1. Asbestos, cellulose, sintered glass; 2. Carbon fiber friction material; 3. Powder metallurgy friction material; 4. Semi-metallic friction material.
