The Zimmermann Brake Kit - Front - 138852 is a comprehensive kit of products designed to service the front brakes of a car. It includes a variety of high-quality components that work together to ensure efficient and effective braking performance. The kit contains three essential items, including brake rotors, brake pads, and brake wear sensors. The brake rotors are the circular discs that attach to the wheels and rotate with them. They are responsible for creating friction with the brake pads to slow down or stop the vehicle. The brake pads are the replaceable components that press against the rotors to create the necessary friction. They are made of durable materials and are designed to withstand high temperatures and heavy use. The brake wear sensors are electronic devices that monitor the thickness of the brake pads and alert the driver when they need to be replaced. This kit is a convenient and cost-effective way to ensure that the front brakes of a car are properly maintained and functioning at their best.
