Wilwood Universal Rear Electronic Parking Brake Retrofit Kit, Black Calipers for 0.39-Inch Rotor Width

Add separate black electric parking calipers to a custom rear brake system using 0.39-inch-wide rotors. Fabricate brackets and plan fused 12V wiring. This is a separate static-parking system for a custom installation, not a complete service-brake conversion. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems along with calipers, rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications each call for components matched to the overall braking arrangement.

Fitment & Compatibility

This is a universal rear parking-brake retrofit for a fabricated installation. Design and supply vehicle-specific caliper brackets after checking the rotor width, sweep, 4.75-inch mount centers and full wheel envelope. No rotors or hydraulic service brakes are included. The motors actuate static parking only; retain a separate hydraulic braking system. Install the supplied controller, switch and harness with a sound ground, an accessory feed and the specified fused 12V supply. Do not bypass the 40-amp fuse or use the parking calipers as an emergency stopping brake. The selected caliper pages specify a 0.15–0.39-inch rotor-width range; 0.39 inch is the nominal maximum, not the disc diameter.
