Rear Brake Over-adjusting

Rear Brake Over-adjusting
Vehicle information: Working on an '85 W350 Chassis. (Under my '78 body) All frame parts, axles and brakes are '85 vintage.
Prefix: All new pads, rotors, drums, shoes, rear brake cylinders, lines (both hard lines and soft) and master cylinder within the last year. Shoes are on correctly, not backwords. Double verified-twice (quad-verified?)
Where I stand now: Every two to three months, my rear, drivers side shoes will overadjust and cause drag and/or lockup in my drum. Emergency brake hasnt been used in over a year. Cables are shot, and wont release brakes.
Question: Why on earth does this keep happening? It drives me (and my very helpful wife) nuts, and is likely to warp my drum and ruin my shoes.
Plead: PLEASE HELP ME... PLEASE, PLEASE, PLEASE!
Thanks guys, Scooter.

I don't claim to be a brake specialist of any sort but I had something similar happen on my 91 where the rear brake drum was over adjusting. I noticed it because I smelled burnt brake shoes. Discovered a bent spring J hook where it went into the shoe and the cable for the adjuster came off the guide. The guide actually looked a little bent. Now which came first, the chicken or the egg, I don't know but the lever that catches the adjuster gear didn't reach anymore and looked like it wore down the edge that catches the teeth. At a glance, I didn't really notice it. but when I took it apart, there it was. Bought a new hardware kit for it and hasn't happened again. But I've got my fingers crossed.
