Wilwood Torino-Style 2.50-inch Rear Parking-Brake Kit — Plain 12.19-inch Rotors and Black Dynalite Calipers

This Torino-style Ford rear kit is built around the 2.50-inch axle-offset measurement. This Forged Dynalite rear disc and parking-brake kit combines black powder-coated 4-piston calipers and 12.19-inch plain-face rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake system.

Fitment & Compatibility

The decisive measurement for this Big Ford new-style/Torino package is a 2.50-inch axle offset. Do not substitute a new-style kit intended for the 2.36-inch arrangement simply because the housing flange appears similar. DS420 shows the correct mounting stack and wheel-clearance profile. Verify those dimensions on the installed axle, including any aftermarket axle shafts or replacement housing ends. The supplied drum/rotors contain a mechanical parking-brake mechanism, so cable travel and routing also need to be resolved before the vehicle is returned to service. The 1990 Town Car application shown below remains conditional on the specified hardware. Have the housing-end measurements available when asking PMB Performance to help confirm a modified rear axle.

The application table below identifies the model-year and factory-equipment combinations. Match the entire row, including its numbered notes.

Package and installation requirements

• The rear rotor incorporates a parking drum with internal mechanical shoes. This arrangement keeps the parking function independent of hydraulic pressure at the Dynalite caliper.
• Parking cables and flexible brake lines are not supplied. The referenced universal cable kit is 330-9371; its final fit may involve adapting the cable or the vehicle.
