Product details
Plain vented iron rotors work with red four-piston lug-mount calipers in this axle-end rear package. The parking-brake shoes operate inside the rotor, leaving cable adaptation as a separate installation requirement. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility
Use the Big Ford New Style flange and 2.50-inch axle offset to identify the correct 1990 Town Car installation. Check axle-register fit and wheel clearance before connecting the separate brake hoses. 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.
