The Zimmermann Brake Kit - Front - 138643 is a comprehensive kit of products designed for the front brakes of a car. It includes four separate items, each serving a specific purpose in maintaining the functionality and safety of the vehicle's braking system.

The first item is a set of front brake pads, which are essential for creating friction and slowing down the vehicle when the brake pedal is pressed. These pads are made of a durable material and are designed to fit perfectly with the car's braking system.

The second item is a set of front brake rotors, which are the discs that the brake pads press against to create the necessary friction. These rotors are made of high-quality materials and are designed to withstand the heat and pressure of braking.

The third item is a set of front brake calipers, which are responsible for applying pressure to the brake pads and pressing them against the rotors. These calipers are precision-engineered and ensure that the brake pads make even contact with the rotors for efficient braking.

The final item in the kit is a set of front brake hardware, which includes various small components such as clips, pins, and springs that are necessary for the proper functioning of the front brakes. These hardware pieces are made of durable materials and are designed to withstand the wear and tear of regular use.

Overall, the Zimmermann Brake Kit - Front - 138643 provides all the necessary components for a complete front brake replacement, ensuring optimal performance and safety for the vehicle.
