The Zimmermann Brake Kit - Rear - 138712 is a comprehensive kit of products designed to service the rear brakes of a car. It includes four objects which are specifically chosen to ensure proper functioning and maintenance of the vehicle's rear brakes. The kit contains brake pads, brake rotors, brake calipers, and brake hardware. These components work together to provide reliable and efficient braking performance for the car. The brake pads are used to create friction against the brake rotors, which are connected to the wheels, to slow down and stop the car. The brake calipers house the brake pads and are responsible for squeezing them against the rotors. The brake hardware, such as clips and pins, help to secure and support the other components in place. This kit is essential for maintaining the safety and functionality of a car's braking system.
