Wilwood Half-Inch Kart Master Cylinder Replacement, Without Mounting Bracket

This replacement cylinder services an existing Wilwood Kart master assembly without supplying a new mounting bracket. The bare aluminum body uses a half-inch bore and a short 0.70-inch stroke for the specified compact racing hydraulic arrangement. For motorsport, street-performance and specialized applications, Wilwood Engineering designs and manufactures disc brake systems and their components. The Camarillo, California company was founded by Bill Wood in 1977. Its range of rotors, calipers, valves, fittings, brake lines and master cylinders supports assemblies whose individual parts must be selected to work together.
