Wilwood Rear Black D154 Parking Brake Conversion, Small Ford Housing, 2.50-Inch Offset; Conditional Lincoln Town Car (1990)

Black D154 calipers and internal parking shoes are supplied with plain vented rotors in this Wilwood Small Ford rear package. The matching housing must have a 2.50-inch axle offset, distinct from the 2.66-inch Small Ford alternative. The listed 1990 Lincoln Town Car application requires physical axle verification 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

Measure flange bolt spacing, bearing arrangement and offset against DS857 and the axle worksheet. Do not select solely by the Town Car name, especially after an axle change. Check the rotor hat's fit over the axle flange and wheel studs before attaching the brackets. Suitable hydraulic hoses and cable linkage must be provided separately. Verify wheel fit with the conditional 16-inch profile; a 15-inch wheel may be possible only if the entire clearance template fits.

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