The Zimmermann Brake Kit is a comprehensive set of products designed for the front and rear brakes of a car. It includes various components that are crucial for maintaining the braking system of a vehicle. The kit contains five different items, which are not specified by brand name but rather by their type of product. These include brake pads, rotors, calipers, brake lines, and hardware. Each of these components plays a vital role in ensuring the safe and efficient operation of a car's brakes. The brake pads provide the necessary friction to slow down or stop the vehicle, while the rotors are the discs that the pads press against. The calipers are responsible for squeezing the pads against the rotors, and the brake lines carry the brake fluid to the calipers. The hardware included in the kit ensures that all these components are properly installed and functioning. This comprehensive kit is essential for maintaining the overall performance and safety of a car's braking system.
