The ATE Brake Kit is a comprehensive set of products designed for use on a car's front and rear brakes. It includes six different components, each with its own unique function. The first component is a set of front and rear brake pads, which are responsible for creating friction against the brake rotors to slow down or stop the vehicle. The second component is a set of front and rear brake rotors, which are the discs that the brake pads press against to create friction. The third component is a set of front and rear brake wear sensors, which monitor the thickness of the brake pads and alert the driver when they need to be replaced. The fourth component is a set of front and rear brake calipers, which house the brake pads and apply pressure to them. The fifth component is a set of front and rear brake pad retaining clips, which hold the brake pads in place. Lastly, the kit includes a set of front and rear brake pad shims, which help to reduce noise and vibration during braking. This ATE Brake Kit is a complete package, providing all the necessary components for a car's front and rear brake system.
