just had a look in me landy and found a pool of liquid under me clutch pedal, it looks like me M/C had developed a leak after being left idle over the last couple of months, the annoying thing its not that old i replaced it last year ffs!
I've been stung by ****part: rear leaf springs, one side sagging and the dowel pins were not the correct diameter. I think I'm going to use genuine stuff as much as possible now. A few years ago I fitted a genuine clutch 90/110 master cylinder to my SIII no problems - it seemed identical apart from a plastic reservoir cap.
