Product details
This rear conversion pairs red Dynapro calipers with drilled-and-slotted 12.19-inch rotors and internal parking-brake assemblies. It fits a measured Big Ford New Style axle-end configuration rather than every axle carrying a Ford name. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.

Fitment & Compatibility
Check the actual housing end, wheel pattern and 2.50-inch axle offset. Independent parking-brake cables and hydraulic hoses must be selected for the installation. 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.
