The Zimmermann Brake Kit is a comprehensive set of brake components designed for use on a car's front and rear wheels. This kit includes four objects, each with a specific function in the braking system. The first object is a set of brake pads, which are responsible for creating friction against the brake rotors to slow down and stop the vehicle. The second object is a pair of brake rotors, which are the discs that the brake pads press against to create the necessary friction. The third object is a set of brake calipers, which house the brake pads and are responsible for squeezing them against the rotors. Finally, the fourth object is a set of brake sensors, which monitor the condition of the brake pads and alert the driver when they need to be replaced. This kit is specifically designed for use on both the front and rear wheels of a car, providing a complete solution for maintaining and replacing the braking system.
