Good news/bad news.
Modded the piston wind back tool but cutting off the original (small) handle, tapping in a thread where the handle went through and put a threaded rod through - bit thicker and longer.
Could now get could purchase with both hands and wind the piston back (which I did).
Got the new disk and pads on and all looked good.
Took for a spin and guess what. Burning smell and the wheel is hot.
So, probably a stuck caliper. Will take it off again tomorrow and see about dismantling it and getting a refurb kit!
