The clutch on our Multipla gets very crunchy after prolonged use and gets to
the point where driving becomes a real pain in the arse.
The clutch itself is approx 1yr old and the slave cylinder was changed just
prior so I wonder if the master cylinder needs changing.

That said I wonder if the fluid needs changing as there is *very* jerky
feedback from the brakes in the wet and if I understand correctly the clutch
and brakes share the same fluid. Would a need to replace the fluid create
the symptoms above?

In either case I would appreciate advice on replacing the fluid or changing
the master cylinder.

Cheers,

Rick
