Wilwood Rear Red Caliper/Plain-Rotor Conversion, Big Ford New Style 2.36-Inch Offset; Lincoln Town Car 1990 Axle-Conditional Fit

This red Wilwood rear kit matches plain-face rotors, D154 service calipers and internal parking shoes to a Big Ford New Style axle end. The package uses the 2.36-inch offset arrangement, which differs from the 2.50-inch alternative. The listed 1990 Town Car requires measured axle compatibility and manufacturer confirmation. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

The correct New Style flange and bearing-retention method must be established using DS861. Measure the axle offset and register, then obtain Wilwood confirmation before applying the 1990 Lincoln Town Car entry to the car. Check the rotor hat over the complete axle-flange envelope rather than only its wheel bolt circle. The parking shoes require adjustment inside the hat, and their cable route must allow both pull and release without binding. Provide the cable connections and hydraulic hoses separately for the completed chassis. Check the shock and suspension space around the bracket, then compare the caliper to the full conditional 16-inch wheel profile. A nominally smaller 15-inch wheel can be considered only after the same section check passes.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
