I did adjust the shoes as per the manual for a 1 ton. However, I still have a leak and suspect this may be the culprit. The back right wheel cylinder is slowly oozing from what I can tell. Tonight I had to give the pedal a second pump to get pressure. The lines look good though, but fluid was leaking out the backing plate in the right rear.
