citypat, 98% of the time when I had drum brakes dragging when they were adjusted in all the way, I found out that the shoes were mixed up (trailing-leading). If you look at the shoes from the side one may have shorter pad material than the other. The shorter pad (leading) should go on the front. If you have one side hard and one easy you may have both leading on one side and both trailing on the other side. Hope this helps.
