Product details

The old-style Big Ford housing pattern and 2.36-inch offset determine this rear conversion. 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.

Technical Details

  • Manufacturer part number: 140-7139.
  • 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.
  • Calipers: 4 pistons; forged aluminum; stainless steel pistons.
  • Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.
  • Caliper finish: Black Powder Coat.
  • 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.
  • Housing/flange arrangement: Big Ford.
  • Axle flange offset: 2.36 in; 59.94 mm.
  • Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.
  • 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.

Fitment & Compatibility

Choose this package by the old-style Big Ford housing end and the measured 2.36-inch axle offset. The word Ford alone is not sufficient: new-style/Torino and Small Ford ends use different bracket arrangements. Compare the mounting flange with DS419 and measure from the axle flange using Wilwood’s worksheet before dismantling the existing brakes. The application list includes a 1990 Lincoln Town Car row, but a changed axle assembly must still satisfy the specified end and offset. This conversion provides rear service discs plus an independent internal-shoe parking brake. Plan the cable connection as part of the installation; the brake kit does not include the cable assembly or hydraulic flexlines. A matching wheel bolt circle is only one check and does not establish housing compatibility.

Use the wheel-clearance drawing in the installation instructions before purchase. The catalog minimum diameter is a guide; barrel shape, spoke clearance and wheel offset still determine fit.

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

Package and installation requirements

  • Service braking uses the four-piston calipers. A separate set of shoes works inside the drum sections of the one-piece rotors to hold the vehicle when parked.
  • Allow for hydraulic hoses and a parking-cable connection in addition to this kit. Wilwood lists universal cable assembly 330-9371, which may need vehicle or cable modifications.
