Product details
Black four-piston Dynapro lug-mount calipers and 12.19-inch plain-face rotors provide the service brake, with a separate internal parking-brake mechanism. Selection depends on the Big Ford New Style housing flange and axle offset. From Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and their components. Founded by Bill Wood in 1977, it serves street-performance, motorsport and specialized applications with master cylinders, calipers, brake rotors, valves, fittings and brake lines. All components must suit the requirements of the complete system.

Fitment & Compatibility
The 1990 Lincoln Town Car row does not replace an axle-housing measurement. Confirm the New Style flange, 2.50-inch offset, axle register and parking-cable connection; hoses and cable hardware are separate. The application table includes a 1990 Lincoln Town Car row, but Wilwood identifies this kit by axle flange and offset. Stock Town Car axle compatibility is not established; confirm the actual or custom axle measurements before purchase.
A maximum flange diameter of 6.61 inches and a 0.050-inch x 45-degree chamfer are specified for rotor clearance. The illustrated register is 2.80 inches; select the documented centering arrangement and match both axle offset and housing-end bolt pattern.
Inspect shock-to-brake clearance as well as the axle dimensions; the installation instructions note that some shock arrangements may need modification or relocation.
Hydraulic hoses/fittings and parking-brake cables, adapters and cable hardware are not included. Choose a compatible cable arrangement for the internal parking brake; universal cable systems may require vehicle or cable modifications.
Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.
