The Genuine VW / Audi Brake Kit - Rear - 178078 is a comprehensive set of products designed for the maintenance and repair of the rear brakes on Volkswagen and Audi vehicles. This kit includes three essential components: brake pads, brake rotors, and brake calipers.

The brake rotors are the discs that the brake pads press against, and they are responsible for dissipating the heat generated during braking. The brake calipers are the mechanisms that hold the brake pads and press them against the rotors. This kit is specifically designed for the rear brakes of Volkswagen and Audi cars, ensuring a perfect fit and optimal performance. It is a genuine product from the manufacturer, guaranteeing high quality and reliability. With all three components included, this brake kit provides a convenient and cost-effective solution for maintaining the braking system of your vehicle.
