Hi everyone
Just wanted to thank those that took the time to offer advise on this one.
Got my drums off finally.
Took a loan of a big puller designed for brake drums to do it. (as well as lots of banging with a hammer)
We broke the wheel cylinder piston ends that mate with the brake shoes but that was the only colateral damage.
A pair of new wheel cylinders is AU$40 so its a good outcome.
Thanks again to you all and I hope to contribute here in the future.
