I drove my 56 F100 with stock brakes for well over 10 years. My truck has a high performance engine/Top loader 4-speed and 390 rear-end gears. I was a pretty crazy driver back then, I drove my truck in heavy traffic here in Phoenix at very high speeds, and discovered the stock brakes pretty much suck no mater how well they're maintained...
The problem with the stock brakes on a 53-56 F100 is:
The brake shoes/drums are extremely narrow! (plus fairly small diamiter) They work alright when they're cool, but they will
very quickly heat up causing severe brake-fade when trying to quickly stop from higher speeds. And simply adding a booster (and/or a modern 2-stage master cylinder/proportioning-valve) wont do very much to help this simple fact... Once the shoes/drums heat-up past a certain point, they simply cant get a grip to each other, no mater what!
I've now bought another strait axle, that the previous owner had installed large rotors/calipers, from a late 70's-era Ford LTD. Plus I've bought a 9" Ford rear end (with larger/wider shoes/drums, 350-gears & posi track) I'm planning on installing, along with a dual master cylinder/booster and proportioning valve from a late-70's era Ford 1/2 ton truck.
I like using
all-Ford components on my Fords, (and all chevy components on my chevys, etcetera). I'm thinking about trying to find a 9" rear end out of a (77-80) Lincoln Versailles, because they came with factory rear disk brakes. I havent double checked if the width is compatible with an F100 yet, but I was thinking one of these rear ends would be a cool way to achieve 4-wheel disk brakes, using all genuine Ford components, and at a fairly reasonable cost from a wrecking yard or someone parting one out...
Heres what those a 9" Lincoln Versailles rear ends look like:
