Wilwood Small Ford Plain-Rotor Rear Kit with Red Dynalite Calipers — 12.19-inch Parking Brakes, 2.66-inch Offset

For the measured Small Ford end, this red-caliper version retains plain vented discs. 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 Small Ford, 2.66-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

• 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.

Technical Details

• Manufacturer part number: 140-7143-R.
• Housing/flange arrangement: Small Ford.
• Axle flange offset: 2.66 in; 67.56 mm.
• Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.
• Rotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.
• Rotor construction: Iron; vented; Plain Face friction surface.
• Rotor/hat wheel-stud clearance patterns: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm.
• Rotor/hat stud-hole clearance diameters: 0.52 in; 13.21 mm. These are hole sizes, not wheel-stud thread specifications.
• The rotor/hat drilling does not change the vehicle hub or axle wheel bolt pattern.
• Sold as one kit. Mounting hardware is included. Hubs are not included.
• Brake pads are included; use the compound and installation instructions specified for this rotor package.
• Spindles, master cylinder, brake booster and hydraulic brake lines are not included.
• Calipers: 4 pistons; forged aluminum; stainless steel pistons.
• Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.

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.

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