The ATE Brake Kit - Rear - 134987 is a comprehensive kit of products designed for use on a car's rear brakes. It includes four different components, each designed to provide specific functions and improve the overall performance of the brakes. These components include brake pads, brake rotors, brake calipers, and brake hardware. The brake pads are responsible for creating friction against the rotors, allowing the car to slow down and come to a stop. The brake rotors are the discs that the brake pads press against, creating the necessary friction for braking. The brake calipers are the components that hold the brake pads and press them against the rotors. Lastly, the brake hardware consists of various small parts that aid in the proper functioning of the brakes, such as clips, pins, and springs. This ATE Brake Kit is specifically designed for use on the rear brakes of a car and is a convenient and cost-effective option for those in need of a complete brake system overhaul.
