The Zimmermann Brake Kit - Front - 138797 is a comprehensive kit of products designed for use on a car's front brake system. It includes three essential components: a set of brake pads, a set of rotors, and a set of brake wear sensors. These products work together to ensure safe and efficient braking performance on the front wheels of a car. The brake pads are responsible for creating friction against the rotors, which helps to slow down and stop the car. The rotors, also known as brake discs, provide a smooth surface for the brake pads to grip onto. The brake wear sensors are designed to detect when the brake pads are worn down and need to be replaced. This kit is designed to be compatible with a variety of car makes and models, making it a versatile and convenient option for car owners.
