Product details
This black Hi-Torque EPB is a right-hand parking caliper operated by an electric motor. Its rotor opening is the nominal 0.81-inch size, and a 4.75-inch lug mount connects it to a correctly positioned bracket. The component does not provide a hydraulic service-brake function, and no hydraulic line attaches to it. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Identify the installed control module and caliper version together when making a replacement. For a new installation, check the rotor’s 0.75–0.81-inch thickness, diameter, offset and friction-track location. Leave clearance for the motor housing and protected wiring, and confirm the rest of the EPB electrical equipment against the manufacturer’s requirements.
