The ATE Brake Kit - Front - 135003 is a comprehensive kit of products designed for the front brakes of a car. It includes four different objects, including brake pads, brake rotors, brake calipers, and brake hardware. These components work together to ensure effective and safe braking for the vehicle. The brake pads are responsible for creating friction against the rotors, while the rotors provide a smooth surface for the pads to grip onto. The calipers contain the brake pistons that apply pressure to the pads, and the brake hardware includes various small pieces such as bolts and clips that help secure the other components in place. This kit is designed to provide all the necessary parts for a complete front brake replacement, making it a convenient and reliable option for car owners.
