Anyone had luck with a replacement Shimano piston (I know these aren't supposed to be owner serviceable)?
I can only find metal or ABS replacement pistons on Alix rather than ceramic.
I bought mine in the uk while I was in Belgium so returning and warranty was a pita so I just bought a new one. AFAIK shimano knows there is a fault somewhere (I had the same shit as you) so should replace it under warranty.
Found the reason behind a leaky piston.
