The ATE Brake Kit - Rear - 134997 is a comprehensive kit of products designed for a car's rear brake system. It includes various components that are essential for maintaining and repairing the rear brakes of a vehicle. The kit contains four different objects, each serving a specific purpose in the brake system. These objects are a brake caliper, brake pads, brake rotors, and brake hardware.

The brake caliper is responsible for applying pressure to the brake pads, which then press against the brake rotors to slow down or stop the vehicle. The brake pads are the actual friction material that makes contact with the rotors and creates the necessary friction to slow down the car. The brake rotors are the discs that the brake pads press against, and they are responsible for dissipating heat and providing a smooth surface for the brake pads to grip onto. Finally, the brake hardware refers to various small components such as clips, pins, and springs that hold the brake system together and ensure proper functioning.

Overall, the ATE Brake Kit - Rear - 134997 is a complete package of essential components for maintaining and repairing a car's rear brake system. It is designed to provide convenience and peace of mind for car owners, ensuring that their vehicle's brakes are in good working condition.
