Product details
A black right-hand housing and electric Hi-Torque drive identify this 1.10-inch-width EPB caliper. It operates as a parking brake without a hydraulic inlet. Selecting it requires both a suitable rotor and an electrical control arrangement that is intended for this motor; matching the outer finish alone is insufficient. 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
Use the exact caliper reference to confirm the motor and the 4.75-inch lug format. Measure rotor thickness and locate the friction track before designing or checking the bracket. The surrounding wheel and suspension must clear the drive housing, and the completed parking system needs its controller, wiring and switch checked as a coordinated installation.
PMB Performance brings over 20 years of brake and parts experience to selection questions. Send the existing caliper reference and brake-package details for help checking compatibility.
