These kits allow you to put disc brakes on your 1948-56 Ford 1/2 ton pick-ups. No spindle modifications are required.

Basic Disc Brake Kit:

  • This basic disc brake kit installs '70-'77 Camaro rotors and '70-'77 Camaro (or GM equivalent) single-piston calipers on 1948-52 F1 and 1953-56 F100 Ford half-ton pickup truck spindles.

Rotor:

  • 11" front disc brake rotor
  • Has a 5 on 4-3/4" bolt pattern.

Caliper:

Mid and full size GM style caliper is a standard full size GM caliper used for years on many vehicles (1969-72 Chevelle, 73-77 A-Body, 1969-1981 Camaro, 1977 Caprice, S-10 pickups, etc). It will fit any bracket / spindle designed for the large GM calipers (7” mount width). 

  • 7/16"-20 inlet so you can use the readily available brake hoses and hardware from Pre-1978 GM midsize cars
  • Fits 1" thick rotor. 2.8" diameter pistons installed
  • Has 7-1/16" center to center mounting holes
  • The width between mounting tabs is 2-3/4"
  • Depending on the spindle and rotor size it will not fit in most 14” wheels (nor in 15” drum brake wheels)

Wheel Bearing:

 Fits tapered-bearing hubs. Works with stepped shaft spindles

  • Steel
  • Outer bearing cones

Brake Pads:

  • Only use full metallic pads on coated rotors.
  • Organic compound for use on cast iron rotors, long life, low wear

Bearing Cups:

These steel inner bearing cones are replacement for our GM to Ford brake conversion bearing and seal kits. Fits tapered-bearing hubs. Works with stepped shaft spindles.
