Product details
The black XRS4R/EPB package places 14-inch GT rotors on the specified Big Ford New Style axle. A four-piston hydraulic caliper and a separate electric parking caliper serve each side, with the controller, switch and wiring harness 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 components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

Fitment & Compatibility
Fit the 14-inch XRS4R/EPB assembly only after verifying the Big Ford New Style housing end and 2.50-inch axle offset. The worksheet establishes the required flange, register and bearing dimensions; the table's 1990 Lincoln Town Car listing is conditional on that hardware. Included electric parking calipers operate through the supplied switch, control unit and universal harness. They are a parking system and must not be used for a moving emergency stop. Hydraulic hoses are not included. Check clearance for both calipers, the larger rotor and the electrical connections. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
