Started refurb on my friend Mike's car's master cylinder after it drained all it' s fluid over the lockdown.
It's the ATE dual piston version with circlip at the piston rod end retaining the innards & has the clamp bolt centrally fitted which once removed along with the internal circlip should allow the piston assembly removal.
Only it won't-the circlip comes out followed by the steel washer & the end rubber seal behind which is a nylon washer ( not mentioned in the Haynes manual covering this earlier model & not even discussed in the official workshop manual,it only says replace the master cylinder )-it feels as if there is another bolt somewhere but there isn't .
I can't believe that this is caused by say one of the internal seals/ backing steel washers catching on some groove or other that isn't visible.
Does anyone have any ideas please - don't want to use more force & cause unnecessary internal damage.
