Wilwood High Volume Single Brake Master Cylinder, 3/4-inch Bore and 8.2 oz Reservoir

The 3/4-inch High Volume master supplies one hydraulic circuit from an integral 8.2 oz reservoir. Its aluminum body, removable steel lid and bellows seal suit a serviceable racing brake installation with a matched pedal assembly. Disc brake systems and components are the focus of Wilwood Engineering's design and manufacturing work for street-performance, specialized and motorsport applications. Bill Wood founded the Camarillo, California company in 1977. Its master cylinders, calipers, fittings, valves, brake lines and rotors are chosen according to the needs of the complete brake system.
