Wilwood Anodized Left Hi-Torque EPB Caliper, 0.75–0.81-Inch Rotor Thickness

The anodized left-hand Hi-Torque EPB is an electric parking caliper for the 0.81-inch nominal rotor-width package. It holds the rotor through motor-driven pad application and does not connect to a master cylinder. The exact specifications identify a 4.75-inch lug mount and an 11.00–14.00-inch rotor diameter envelope. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility

Match the left drive orientation and available mounting space first, then establish the rotor’s lateral position relative to the bracket. Use the 0.75–0.81-inch thickness limits for this part rather than the broader EPB family range. Controls, harness protection and switch operation are essential parts of the completed parking-brake installation.
