Hello.

Any tips for re-fitting calliper pistons without wrecking the seals? (first attempt at this has ended up with one calliper leaking from the seal [under brake pressure] - pretty sure it was the brutal manner of re-fitting the piston that has done for the seal(s) - 25+yr old rubber style piston seems awfully tight compared to the alloy ones I've worked on before - wonder - do they swell with age?].

Thanks in advance.
