Product details
A red powder-coated body carries the Hi-Torque electric parking drive on this right-hand EPB caliper. It suits the nominal 0.81-inch rotor width and has a lug-mounted bracket interface. This standalone parking component needs a separately functioning service brake; the listed single piston is mechanically driven by the motor rather than hydraulic pressure. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.

Fitment & Compatibility
Compare the rotor width and motor specification with the part already fitted. A new bracket must locate the pads correctly and allow the caliper’s intended movement without contact with the wheel or axle. Verify the 4.75-inch mount pattern and an appropriate controller, harness and operating switch before putting the parking system into use.
