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.

- 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"

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.

Product was pretty bad
The kit came with spindle Adaptors that slide on the spindle to increase its size for the larger GM bearings and seals. The seals included in the kit were so loose fitting on the adaptors that I could see daylight between them. No way this would retain grease. The brake shoes were so poor quality that that would move around 3/8 of an inch much in all directions once installed and they would actually touch the center of the hub and would have ground against it. I had to source and pay for my own seals and brake shoes. Customer service was no help as they were not familiar with the kit and when I tried to explain the issues to The tech he said," well you bought a budget kit". I would not recommend this kit to anyone and would not buy it again.

Everything fit as expected except didn't need the spacers on the spindles, not sure why they're included in the kit. And I believe the brake pads should come with the anti-raddle clips. I was made to order those separate.

I would buy this again.
