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

Usually the signs of brake fluid going off is brake fade being
experienced earlier.

Fluid condition will not make any noticeable difference to clutch operation,
it would work for a while at least with water in the system.
Clutch and brake fluid should be changed every two years or so as it
attracts water, effectively the fluid in the clutch circuit doesn't go
anywhere and the fluid down at the slave cylinder must be quite fresh as you
had a new one quite recently.

If the clutch is apparently not disengaging when hot then it means that
either the clutch is not disengaging fully or the main shaft of the gearbox
is being dragged along by the engine.

There is a slim chance of a ballooning flexible hose, possibly the release
mechanism on/in the gearbox is stiff. Possibly the clutch itself is faulty,
incorrect grease application during clutch fitting can give the same effect.
if it uses one, the crankshaft spigot bearing may be at fault and drags the
mainshaft with it (this was common on some fords) although many vehicles no
longer have a spigot bearing.

Thanks for that, i'll take a look but I have the feeling that there are too
many forums in my life!

Thanks for the above.

If it makes any difference the problem is notably worse on a hot day.

I am sure it is fluid compression related as it occasionally gets so bad
that I can't get the car in gear unless I switch off the engine for a moment
and then fire it back up again.

then the first thing to try is to bleed some fresh fluid through, perhaps
some air was left in from before?
