Beringer's brake master cylinder is a true high-tech development with its radial placed hydraulics and the hand lever rolling on 3 ball bearings to reduce friction. This combination provides maximum braking power with the least hand force. The piston diameter is optimized for use with any 4 or 6 piston Beringer caliper in either single or dual applications. Brake master cylinder and matching lever assembly for cable operated clutch are available in polished, black, or chrome finish.
