Changed my discs today as the drivers side had worn the grooves off the disc so I knew it was a sticky piston etc.

Anyways I had the pistons out and cleaned it all up. The pistons are in very good shape so I put in New piston seals but there still stiff and granchy. Anyone else had this?

Don't fancy wearing through another set of rotors at 200 quid ago.

Its a ash 310 Renault brembo set up by the way.
