Ok here are some pictures.
The problem is that i cant remember which one is go first in the master cylinder

.
Anyway the small one was the last one if i can recall but i am not quite sure.
So what do you thing guys . Is that what Peter told me abou the overpressure ? I think that the one seal is standing backward and the one of the other pistons seems ready to turn.




Peter can i use the same sealings or do i have to wait till you send me new ones ?
i am kind of reliefed now guys...
