Wilwood Black Rear Electric Parking Brake Retrofit Kit for 1.10-Inch Rotors, Calipers with Controller, Harness and Switch

This black EPB retrofit kit is the 1.10-inch rotor-width configuration, supplying motor-driven rear parking calipers and the electrical controls needed to actuate them. It adds a stationary holding function alongside the vehicle's hydraulic service brakes. The installer must design appropriate caliper brackets and confirm the rotor contact position, motor clearance and wiring route. No replacement rotors or hubs are included. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines are selected to suit the complete braking system.

• No replacement wheel hubs are supplied; retain or provide the documented matching hub arrangement.
• Published piston bore: 1.25 inches. Supplied pad compound: BP-10.
• Rotor compatibility: 1.04–1.10-inch thickness, nominal 1.10 inch; rotor diameter 11.00–14.00 inches. Caliper mounting centers: 4.75 inches. Custom brackets must locate the pads correctly on the rotor.
• Includes paired electronic parking calipers, controller, wiring harness, switch and supplied control hardware. Custom caliper mounting brackets, rotors, hubs and hydraulic service brakes are not included.

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.
