Ive had my coach (639) raised to replace the Aquahot and generator exhaust system.  The front and mains were on heavy duty ramps and the body was cribbed with jack stands. The tags were not raised and still resting on the ground as the mains were only raised about 5".  It sat like that for sever weeks as I ended up having to completely rebuild the entire aquahot (unfortunately not just the exhaust). Anyway, I pulled the coach out and drove about 1/2 mile when the passsenger side tag locked up.  I park the coach and called Newell for advice.  They immediatley asked if the coach had been sitting and said the brakes can get stuck and told me how to cage the brake.  I went back with the 1' ( I think) socket and backed the bolt out of the brake chamber.  I was not sure how far to back it out and did not want it to fall completely out.  After backing the bolt out with the ratchet it started to spin freely.  I backed it out by hand until it got tight.  I then put the socket back on it a made probably 8 to 10 complete 360 degree turns.  The wheel was still locked up.  I did a few more turns and same thing.  I then played with the tag weight increase/ decrease button and it finally started to turn.  I got the coach home, but not sure where to start.  This senerio does not sound like the brake getting "stuck" as it rolled fine for 1/2 mile before locking up.  Not sure why the tag weight button would change thinkgs aside from maybe applying enought weight to turn a still partially stuck brake.  Any ideas????
