Wilwood Rear EPB Parking-Brake Retrofit with Red Calipers for 1.10-Inch Rotors, Complete Controller and Harness Package

Choose the red-caliper EPB retrofit for a rear installation using the specified 1.10-inch rotor width. The kit includes the paired electric parking calipers, controller, switch and harness, but it is not a complete hydraulic brake conversion. Custom brackets are normally required to locate the calipers correctly on the existing rotors. Check motor/body clearance and electrical installation requirements before committing to the fabrication. Wilwood Engineering was established in 1977 by Bill Wood in Camarillo, California. The company designs and manufactures disc-brake systems and components, from calipers and rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized installations. Each component must match the rest of the brake system.

Fitment & Compatibility

Universal retrofit for a custom rear parking-brake installation using 1.10-inch-thick rotors; no vehicle-specific bolt-on fitment is claimed. Confirm caliper width, mounting-center spacing, rotor diameter/contact position and clearance for the motors, wheels and suspension. Custom brackets are normally required and are not included. Retain a properly configured hydraulic service-brake system. The EPB is intended for static parking hold, not emergency stopping, and needs the documented electrical supply, fused wiring and controller installation.

PMB Performance brings 20+ years of parts and fitment experience to brake selection. Send the actual spindle or axle details, existing brake package and wheel measurements for help checking this combination.
