A light weight hydraulic disc brake system, featuring several innovations, has been developed for on highway, recreational vehicle use. The system uses aluminum components for the major structural members of the brake and master cylinder. A plastic master cylinder piston is used. The brake system uses a stamped steel rotor and metallic friction materials. The components of the system have passed life cycle, environmental and vibration tests, which were based on Kelsey-Hayes test requirements for the automotive industry.
