The Zimmermann Brake Kit - Front - 138586 is a comprehensive set of products designed to service the front brakes of a car. The kit includes four components, each designed to improve the performance and functionality of the car's braking system without specifying the brand of the parts. These components include brake pads, rotors, calipers, and brake lines. The brake pads are designed to provide friction against the rotors, allowing the car to slow down and stop effectively. The rotors are circular discs that rotate with the wheels and are squeezed by the brake pads to slow down the car. The calipers are responsible for holding the brake pads in place and applying pressure to the rotors. Lastly, the brake lines are the tubes that carry brake fluid from the master cylinder to the calipers, allowing the brakes to engage when the brake pedal is pressed. This kit is a convenient and essential package for maintaining the front brakes of a car, ensuring safe and efficient braking performance.
