I took the slave cylinder off as the master cylinder piston was also seized in the bore and fluid totally dried out and assumed the slave cylinder would be in the same condition, as has proved to be the case.
I cannot budge the piston with compressed air so thought if I pushed it in a smidgeon it might break whatever is holding it. Managed to move it about 1mm but it still wouldn't budge. Squirted some WD40 around the edge of the piston in the vain hope that might help, but no. The piston appears to be in almost as far as it can go
Next step was to try gently heating the body of the cylinder but that made no difference, either.
The only thing i can think of now is drilling a hole in the middle of the cover and whacking the piston out with a punch then tapping the hole and putting a bolt in it to seal it back up again. This is all assuming the bore is still OK or I don't wreck it getting the piston out...
Does anyone have any bright ideas on how to remove the piston?
I can get one from a UK wrecker for about 20 quid (and the postage to Australia is almost as much again) but who knows if that one will be any better...
