The Zimmermann Brake Kit - Rear - 138405 is a comprehensive package of products designed for servicing the rear brakes of a car. It includes a variety of essential components to ensure optimal performance and safety of the vehicle's braking system. The kit contains three objects, including brake pads, brake rotors, and brake calipers. These parts work together to provide the necessary friction and pressure to slow down or stop the car when the brake pedal is pressed. The included brake pads are made of durable materials and are designed to fit perfectly onto the brake rotors. The brake rotors are responsible for providing a smooth surface for the brake pads to make contact with, and the brake calipers hold the brake pads in place and apply pressure to the rotors when the brakes are engaged. This Zimmermann Brake Kit is a reliable and convenient solution for maintaining the rear brakes of a car and ensuring safe and efficient braking performance.
