The reasons for a clunking sound when stepping on the brake are: 1. There are foreign objects or hard spots on the brake pads; 2. Issues with the brake vacuum booster pump; 3. Blockage in the booster pipe due to foreign objects. The maintenance methods for brakes include: 1. High-temperature protection to prevent corrosion of the brake system and avoid brake pads seizing due to high temperatures; 2. Cleaning oil stains from brake discs and drums to ensure good heat dissipation; 3. Regularly replacing brake fluid; 4. Periodically checking the thickness of brake pads or shoes. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and drums, as well as between the tires and the ground, thereby slowing down or stopping the car.
