Product details
The left-hand anodized Hi-Torque EPB provides electric parking actuation for a 1.10-inch nominal-width rotor. It is an aluminum-and-steel caliper with a lug-mounted bracket interface and no brake-fluid inlet. This version belongs to a coordinated parking system with the appropriate motor controls and a separate service-brake assembly. 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
Check the exact rotor and installation drawing before choosing the caliper. Its permitted thickness is 1.04–1.10 inches, with an 11.00–14.00-inch diameter envelope. Allow space on the left-hand side for the motor housing and lead, verify the 4.75-inch bracket geometry and confirm that the controller is intended for the Hi-Torque drive.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
