The drum came off ok, and all looked ok, just needed freeing up with the mallet, once off it definitely needed a clean , there was a lot of dust, dirt in there , and before having this issue I had probably washed it and probably soaked the wheels , left it parked up. I think it got then stuck because I dont use the car as a daily driver and it hadnt been moved in last month or so. I am not sure it was anything to do with the handbrake although I had assumed so, had parked up with handbrake on, just assumed the handbrake was issue. Seems to be fine now , going for MOT next weekTake the drum off to inspect it. It doesn't seem right to me that it got stuck so badly it would drag the wheel and suddenly everything is fine...
