Wilwood Polished 12.19-inch Rear Brakes — Small Ford 2.66-inch End, SRP Rotors with Parking Shoes

This polished Small Ford assembly combines patterned rotor faces with mechanical parking-brake shoes. For Small Ford, 2.66-inch offset, Wilwood specifies polished 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this rear package. Bill Wood founded Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.

Package and installation requirements

• One-piece vented iron rotors include an inner drum for the parking shoes. The service caliper operates the disc face; parking is provided by the separate cable-operated mechanism.
• The package needs separately selected hoses and parking cables. Wilwood’s universal 330-9371 cable reference is not a promise of installation without modification.

Fitment & Compatibility

Small Ford housing ends use this kit’s 2.66-inch axle-offset arrangement. They should not be confused with either old-style Big Ford ends or the later Torino flange. Identify the end from the mounting dimensions in DS423, then measure the installed axle offset; an axle sold as a Ford replacement may have different ends. The internal-shoe parking brake is housed within the one-piece drum/rotor rather than operated by the service caliper. Check the planned cable connection and its operation when laying out the installation. The table’s 1990 Lincoln Town Car listing is still subject to these Small Ford measurements. Finally, use the wheel template on the actual wheels: the listed nominal diameter alone does not establish clearance around the four-piston caliper.

Review the fitment table and numbered notes below together; a matching model name alone does not establish the installation.
