Product details
Black finish distinguishes this left-hand EPB motorized parking caliper. The body is dimensioned around a nominal 0.81-inch rotor width and uses the 4.75-inch mounting format. Hi-Torque motor operation replaces a parking cable input; it does not convert the part into a hydraulic caliper or establish vehicle-specific compatibility. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Check the exact caliper and controller pairing before ordering, including any requirements for the Hi-Torque drive. The bracket must set both radial height and rotor offset while leaving the motor unobstructed. Inspect wheel clearance and protect the electrical lead from heat, abrasion and moving suspension components after the complete system is assembled.
