The ATE Brake Kit - Rear - 135069 is a comprehensive kit of products designed for use on a car's rear brake system. It includes a variety of components to help maintain and improve the performance of the brakes. The kit contains three main products: a set of brake pads, a set of brake rotors, and a set of brake calipers. These components work together to provide efficient and reliable braking for the vehicle. The brake pads are responsible for creating friction against the rotors, which in turn slows down the vehicle. The rotors are the discs that the brake pads press against, and the calipers are responsible for squeezing the brake pads against the rotors. This kit is designed to be a complete solution for replacing or upgrading the rear brakes on a car, providing all the necessary components for a smooth and safe driving experience.
