Product details
An individual Wilwood EPB left electric parking brake caliper, finished in black, is specified here. Use the 1.25-inch piston bore, 4.75-inch mounting centers and 1.10-inch rotor width to compare it with the existing brake assembly. 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. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system.
