Wilwood Rear D154 Parking Brake Kit, Black Calipers Ahead of Axle, Big Ford New Style 2.50-Inch Offset; Conditional Lincoln Town Car (1990)

This Wilwood rear kit positions both black D154 service calipers ahead of the axle centerline. Plain 12.19-inch rotors and internal parking-brake shoes are selected for a Big Ford New Style housing with 2.50-inch axle offset. The mounting direction is around the rear axle; it does not make this a front-wheel brake kit. 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

Use DS862 to confirm the forward-caliper bracket arrangement, shock clearance and housing flange. Measure the bearing and offset, and verify the listed 1990 Lincoln Town Car application directly with Wilwood. Vehicle year alone cannot establish the required axle end. Inspect the rotor-hat fit over the studs and flange before arranging the separate parking cables and brake hoses. The wheel needs the conditional 16-inch profile; some 15-inch designs can fit only after a complete clearance comparison.

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