Sorry Jim, I've been away for a few days...

Well, it sure sounds like the retraction problem I spoke of earlier. It's time to pop that RR drum and perform an inspection. Try spreading the shoes apart using a screw driver between the shoe and the pin stop, and see if the springs will retract them all the way back to the pin or not. They should snap right back to the stop, but I'm betting they won't. Their probably hanging up on something, either that or one of your brake components is shot (Wheel Cylinder, Springs, etc)
