Wilwood 1-Piston EPB Caliper, Red — Left Lug Mount for 0.81-Inch Rotor Width

Select this red left Wilwood EPB electric parking brake caliper by the actual lug mounting geometry, not just its appearance. The 1-piston unit uses 1.25-inch bore dimensions and is configured around a 0.81-inch-wide rotor. An electric motor and reduction drive operate this separate parking caliper. The brake-system controller, harness and dashboard switch are separate components. Mounting geometry, motor clearance and rotor width must all be checked; this is one caliper rather than a complete parking-brake conversion. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake system.
