It includes a variety of components that are essential for maintaining the functionality and safety of the brakes. The kit contains five different items, each serving a specific purpose in the brake system. These include brake hoses, which are flexible tubes that carry brake fluid from the master cylinder to the brake calipers or wheel cylinders, brake line fittings, which connect the brake hoses to the rest of the system, brake line clips, which secure the brake hoses in place, and brake line washers, which create a tight seal between the brake line fittings and the brake hoses. This comprehensive kit is essential for ensuring the proper functioning of a car's brakes and can help prevent potential brake failure.
