Brake Hose/Line: Description and Operation

The purpose of the brake tubes and flex hoses is to transfer the pressurized brake fluid developed by the master cylinder to the brakes at each wheel of the vehicle. The flex hoses connect the chassis brake tubes, which are mounted to the vehicles underbody, to the brake at each wheel, allowing for movement of the vehicle's suspension. The brake tubes are steel with a corrosion-resistant nylon coating applied to the external surfaces. The flex hoses are made of reinforced rubber.
