The Zimmermann Brake Kit - Front - 138266 is a comprehensive kit of products designed for use on a car's front brake system. It includes four separate components, each serving a specific purpose in maintaining and improving the performance of the brakes. The contents of the kit are as follows:

1. Brake pads - These are the friction materials that come into contact with the brake rotors to slow down or stop the car. They are made of high-quality materials and are designed to provide optimal braking power and durability.

2. Brake rotors - These are the circular discs that the brake pads clamp onto to create friction and slow down the car. The rotors are made of high-grade materials and are precision machined to ensure smooth and consistent braking performance.

3. Brake wear sensors - These are electronic sensors that are attached to the brake pads and alert the driver when the pads are worn down and need to be replaced. This helps prevent damage to the brake system and ensures safe driving.

4. Brake hardware - This includes various small components such as clips, pins, and springs that are essential for proper installation and functioning of the brake pads and rotors. They are made of durable materials to withstand the high temperatures and pressures of the braking process.

Overall, the Zimmermann Brake Kit - Front - 138266 is a high-quality and convenient solution for maintaining and upgrading the front brake system of a car. It is designed to provide reliable and efficient braking performance, ensuring the safety and smooth operation of the vehicle.
