Product details

Wilwood front drag brakes for matched early Ford/Mercury spindles, with 11.75-inch steel rotors. Check V8, production-split and vehicle-weight limits. The manufacturer is Wilwood Engineering of Camarillo, California, established in 1977 by Bill Wood. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and lines for motorsport, street-performance and specialized vehicles; suitability depends on the full brake-system configuration.

Technical Details

  • Manufacturer part number: 140-4307-BD
  • Rotor material and size: Choose this 11.75 x 0.35-inch drilled rotor configuration. The rotor material is steel and its construction is solid.
  • Caliper specification: Finish selection is type iii anodized. Each forged aluminum caliper carries 4 pistons with stainless construction.
  • Caliper interface: 1/8-27 NPT inlet thread; calipers attach through the specified lug mounting layout.
  • Hub wheel drilling: 5 x 4.5 in; 5 x 4.75 in (5 x 114.3 mm; 5 x 120.65 mm)
  • Wheel fit: Check the wheel-clearance diagram; the listed minimum wheel diameter is 15 inches.
  • Kit supply: hubs, mounting hardware
  • Not included: master cylinder, booster, spindles, flexible brake lines
  • Manufacturer use/weight limit: For use on cars up to 2800 pounds with rear discs or on cars up to 2400 pounds with rear drums

Fitment & Compatibility

Check every relevant table row: early Falcon, Ranchero, Comet and Cyclone applications can require V8 spindles, and the 1970 Falcon/Maverick drum-spindle rows have an August 24, 1969 production cutoff. The 1970 Mustang row is GT350/GT500 disc-spindle only. Use DS-246 to confirm the installed spindle and observe the 2,800-pound rear-disc or 2,400-pound rear-drum vehicle limit. Flexible lines and any master-cylinder pushrod changes are separate requirements.
