My 54 2-ton has one and it's never worked, yet I drive it all the time and
brakes acl like standard, a little hard with gravel load. I would like it to
work. I had a 59 Ford with identical system and it could put you through the
window if you wanted it to. Real nice! These trucks both have 4 rear brake
cylinders that are huge and fronts are minimal, one piston on the Ford. I
would think it would be overkill on your 1/2 ton and may grab too good. You
could use a disc brake conversion with about same work, keep manual and
still have better brakes and stock appearance. They have 6-bolt rotors now.
Wheel fit may be something to look into on those. They make kits to rebuild
Hydros, Carter's has them. Brake shops won't, they send them out and runs
about $200 or so to get rebuilt. Pits in the cylinder would be my biggest
fear and no parts available. The shop manual has a big section on them and
it looks complicated.
