Ford 73-84 F100, F150, Bronco Rear 14" Big Brake Kit
Fourteen inch rear rotors. Four pistons. A parking brake that actually holds. Most big brake stories stop at the front axle. Then the truck noses down under braking; the rear drums do almost nothing and the back end feels light on wet pavement. Balance is what makes a truck stop straight. This kit bolts 14 inch drilled and slotted rotors and Wilwood FNSL 4-piston calipers to the factory Big Ford axle with no modification. Machined aluminum hats; 6061 radial brackets and laser cut brackets locate everything where it belongs. The internal drum style parking brake is the part people forget. You keep a real mechanical hold on a hill instead of a caliper lever that fades with the pads. Before you order; measure the flange at the back side of the drum. This kit wants Big Ford Old Style flanges with a 2.36 inch offset on a bolt-in sealed bearing axle. Year alone will not tell you; the tape measure will.
