Wilwood Right-Hand ATV Master Cylinder, 19 mm Bore, for DOT 5 Fluid

A right-hand side-mount housing defines this 19 mm ATV master cylinder. Wilwood's exact ordering description specifies DOT 5, and the family uses silicone-fluid-compatible seals in these versions rather than treating all brake fluids as interchangeable. 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.
