The ATE Brake Kit - Rear - 135063 is a comprehensive kit of products designed to service the rear brakes of a car. It includes various components that are essential for maintaining and repairing the brake system of a vehicle. The kit contains three main items, including brake pads, brake rotors, and brake calipers. These components work together to ensure efficient and safe braking performance for the rear wheels of the car. The brake pads are responsible for creating friction against the rotors, which helps to slow down or stop the vehicle. The rotors, on the other hand, are the discs that the brake pads press against to create friction. The brake calipers hold the brake pads in place and are responsible for applying pressure to the pads when the brake pedal is pressed. This kit is suitable for a variety of car models and provides all the necessary components for a complete rear brake system overhaul.
