Wilwood Torino-End Rear Disc Conversion with 2.50-inch Offset — Red Dynalite, Plain 12.19-inch Parking Rotors

The red and plain-face combination retains a separate internal-shoe parking brake. The Forged Dynalite rear disc and parking-brake kit is supplied with red powder-coated 4-piston calipers and 12.19-inch plain-face rotors for Big Ford New Style, 2.50-inch offset. Since Bill Wood founded the company in 1977, Camarillo, California-based Wilwood Engineering has designed and manufactured disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, rotors, master cylinders, valves, fittings and brake lines; all must be matched to the intended brake system.

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.

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.

Confirm the exact model and equipment combination in the table below, then follow its numbered installation notes.
