Cheers guys, I'm not surprised noone else has suffered it to be honest as it's not something I've experienced before. Shimming? ha, I'll be lucky. Circlips are proper snug round the piston. I had toyed with the idea of giving them a rub to maybe take 0.1-0.2 off the thinckness, but quite honestly, I couldn't be arsed.
I used some different e clips in the rebuild. which seem a bit more manly for the job. Down Torch in next week or two to test it out. Should be good.
