I wouldn't use clamps on the piston either. The plastic pistons in the GS have plastic inserts in the centre which have been known to break.
I wish I'd read this thread before cleaning my brakes!
Whilst 'levering' a piston back in I cracked a small hole in the end!
No fluid leaking though, I presume fluid doesn't actually fill the piston right through to the front?
Everything appears to be in working order. Do I have a problem that I don't know about?
