The Zimmermann Brake Kit is a comprehensive set of products designed to service the front and rear brakes of a car. It includes six components: two front brake rotors, two rear brake rotors, two front brake pads, two rear brake pads, two front brake wear sensors, and two rear brake wear sensors. This kit is suitable for a variety of car models and provides all the necessary parts for a complete brake replacement. The front and rear brake rotors are responsible for stopping the car by creating friction with the brake pads. The brake pads are the components that press against the rotors to generate the necessary friction. The brake wear sensors are designed to monitor the wear of the brake pads and alert the driver when they need to be replaced. This kit is a convenient and cost-effective solution for maintaining the braking system of a car.
