Update, installed another new wheel cylinder, reset the proportioning valve, bled brakes with my new speed bleeders and᠁᠁.everything works great! Finally can enjoy the MUCH improved stopping power of my disc brake conversion. Bad “new” wheel cylinder was the problem, just like Jerry predicted.

Added note: rear brake shoes were soaked with brake fluid from leaking wheel cylinder and NO luck finding replacement for ‘49 3/4 ton rear shoes. Soooo, saw on stovebolt that boiling them for half hour or so in water and dish soap will clean them up. Some comments said don’t bother it doesn’t work, get the shoes re-lined. Well, I’m here to tell you it does work – and very well at that! I boiled them outdoors in a turkey size pot for 30+ minutes, dumped the black water and repeated the cycle. Let them dry, gave a blast of brake cleaner and a rough up with sand paper and they are good as ever – good stopping and no grabbing. Thanks to those experienced readers for the old school (and inexpensive) fix. Love Stovebolt.
