The Zimmermann Brake Kit - Rear - 138627 is a comprehensive set of products designed to service the rear brakes of a car. The kit includes three main components: a set of brake pads, a set of brake rotors, and a set of brake calipers. These components work together to provide reliable and efficient braking performance for the rear wheels of a car. The brake pads are made of high-quality friction material and are designed to withstand high temperatures and heavy use. The brake rotors are durable and provide a smooth surface for the brake pads to grip onto. The brake calipers are responsible for applying pressure to the brake pads, creating friction and slowing down the vehicle. This kit is ideal for car owners looking to replace or upgrade their rear brake components for improved safety and performance on the road.
