Wilwood Rear Dynalite EPB Brake Kit with Black Calipers and 12.19-Inch Plain Rotors, Big Ford New-Style Axle, 2.50-Inch Offset

Black Forged Dynalite service calipers and one-piece 12.19-inch rotors make up the hydraulic side of this rear EPB conversion. Dedicated motor-driven calipers provide static parking hold without a mechanical cable connection. The kit is selected by the Big Ford new-style flange and 2.50-inch offset, then by wheel and suspension clearance; it should not be chosen from a vehicle year alone. 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.

• Brake hoses are not included. Select suitable braided lines and fittings for the installation.
• Minimum nominal wheel diameter: 15 inches. The wheel must also clear the actual caliper and rotor profile in the installation drawing.
• Separate electronic parking calipers, controller, wiring harness and switch are included. EPB actuation is electrical; hydraulic service braking remains independent.
• Mounting hardware and the specified pads are included. Spindles, master cylinder and brake booster are not supplied.

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.

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.
