Ford 73-84 F100, F150, Bronco Rear 14" Big Brake Kit

$2,115.00

1973-84 Ford F100, F150 and Bronco rear 14 in big brake kit with 4-piston calipers, drilled and slotted rotors and internal parking brake. Bolts to the factory axle.

  • Balance the truck - 14 inch rear rotors stop the nose dive that a front only upgrade builds in.
  • Bolts to the factory axle - no welding and no axle modification; the brackets locate on the stock flange.
  • Real parking brake - an internal drum style assembly holds on a grade the way a drum always did.
  • Wilwood 4-piston FNSL - the right clamp for the rear; enough to work; not enough to lock the axle early.
  • Drilled and slotted rotors - included; not an upcharge you find at checkout.
  • Measurable fit - a published 2.36 inch flange offset you can check with a tape before you spend a dollar.

Complete Rear Brake Transformation | 14" Kit | Ford Big Ford Axle 73-84

A 14" rear brake kit utilizing 4-piston calipers, LSMFG machined aluminum hats, and radial brackets which bolt directly to the factory axle without modification. Includes drilled/slotted rotors and an internal drum style parking brake assembly. Designed fit 73-84 Ford F100, F150 trucks, and Bronco with Big Ford Old Style axle flanges and a 2.36" offset.

*Fits bolt-in style sealed bearing axles, not tapered roller bearing (unless it has been converted to a sealed bearing).

This kit DOES NOT fit Ford 8.8 c-clip style axles. If you have an axle with that style in your 80-96 F150/Bronco, see our Ford 80-96 F100, F150, Bronco Rear 14" Big Brake Kit.

Please verify your flange dimensions with the image below. This can be done without removing anything simply by measuring the flange at the back side of the drum. Even if your model is listed below, if it does not have the correct flange measurements then the kit will not fit.
