Probably a common problem, my bus is stuck in the garage as the rear nearside drum has seized through shameful non-use for several weeks. Could be the handbrake cable or the shoes. Any hints on how to free it up gratefully accepted, I've tried just reversing out but scraping rubber put me off forcing it any further, also if it suddenly freed under high revs..... totalling the side panel on the garage door frame is not my favourite outcome!
