Wilwood Rear Dynapro Low-Profile Electronic Parking Brake Kit, Black Calipers and 11-Inch Plain Rotors, Big Ford New-Style 2.50-Inch Offset

Combine compact rear service calipers with a separate electronic parking brake on a Big Ford new-style axle housing. This version supplies black Dynapro Low-Profile four-piston calipers and 11.00-inch plain-face rotor/hat assemblies. The EPB system holds the stationary vehicle electrically, replacing mechanical parking cables in this conversion. The specified 2.50-inch axle offset and housing-end geometry must be measured before selecting the kit. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit is one configuration within that disc-brake-system range and must be matched to the vehicle build.

• Brake hoses are not included. Select suitable braided lines and fittings for the installation.

Fitment & Compatibility

Application is controlled by the Big Ford new-style housing flange and a measured 2.50-inch axle offset. The application table lists a 1990 Lincoln Town Car, but the manufacturer does not currently confirm that model application. Do not order for a Town Car by year/model alone; verify the housing-end drawing, bearing retainer and offset first. Check axle-flange diameter, wheel seating, wheel profile and EPB motor clearance through suspension travel. The electronic parking system is for stationary parking hold, not an emergency stop brake. Mounting brackets must allow both service and parking calipers to clear the body and suspension. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.

For fitment assistance, send PMB Performance the vehicle details together with the installed spindle or axle configuration and wheel measurements. We draw on 20+ years of parts and fitment experience to help assess the combination.
