55.2-59 1958 Apache 38 brakes dragging all around.

After looking over you post, I cant find if you replaced the brake shoes. If you did, did you replace all the brake springs? If so do the replacement ones match the old ones? Also, is the pedal return spring pulling the pedal all the way back against the floor board?
I had the same type of problem on my '49. After pulling my hair trying to figure it out, I found the parts house had given me the wrong spring kit. If the truck has sat along time the springs may have lost tension causing the shoes to not pull back from the drums when they get hot.
Good luck finding this one.
