The ATE Brake Kit - Front - 135122 is a comprehensive package of products designed to service the front brakes of a car. It includes three main components, each designed to ensure optimal braking performance and safety. The first component is a set of brake pads, which are responsible for creating friction against the brake rotors to slow down or stop the car. The second component is a set of brake rotors, which are the metal discs that the brake pads press against to create friction. The third component is a set of brake calipers, which are responsible for applying pressure to the brake pads to initiate the braking process. Together, these three components make up the ATE Brake Kit and provide all the necessary parts for a complete front brake service.
