The Zimmermann Brake Kit - Front - 138701 is a comprehensive kit of products designed for use on a car's front brakes. It includes various components that work together to provide efficient and reliable braking performance. The kit contains brake pads, rotors, and calipers, all of which are essential parts of a car's braking system. The brake pads are responsible for creating friction against the rotors, which in turn slows down the rotation of the wheels. The rotors, also known as brake discs, are flat metal discs that are attached to the wheels and provide a surface for the brake pads to press against. The calipers are the part of the braking system that houses the brake pads and applies pressure to them when the brake pedal is pressed. Together, these components work to ensure safe and effective braking for the vehicle. This kit is specifically designed for use on the front brakes of a car and is suitable for various makes and models. It is a convenient and cost-effective option for those in need of a complete brake system overhaul.
