The Zimmermann Brake Kit - Rear - 138490 is a comprehensive kit designed for servicing the rear brakes of a car. It includes three essential components that work together to ensure proper functioning and maintenance of the rear brakes. These components are not specific to any particular brand of car, but rather can be used for a variety of vehicles.

The first component included in the kit is a set of rear brake pads. These are the friction materials that come in contact with the brake rotors to slow down or stop the vehicle. The brake pads are made of high-quality materials and are essential for safe and efficient braking.

The second component is a set of rear brake rotors. These are the flat, circular discs that are mounted on the wheel hub and rotate with the wheels. When the brake pads come in contact with the rotors, the resulting friction slows down or stops the vehicle. The rotors in this kit are designed to be durable and provide smooth and consistent braking performance.

The final component of the kit is a set of rear brake calipers. These are the hydraulic devices that press the brake pads against the rotors when the brake pedal is pressed. The calipers in this kit are designed to be reliable and provide consistent pressure for effective braking.

Overall, the Zimmermann Brake Kit - Rear - 138490 is a complete package that includes all the necessary components for maintaining and servicing the rear brakes of a car. It is a high-quality kit that ensures safe and efficient braking, making it an essential product for any car owner.
