Lost pressure fairly quickly over night but still drivable. It was stood at work in the carpark during the day and when I came to leave I could not disengage the clutch. I took the cap off the master cylinder and pumped the peddle for about 10 minutes. It gave me enough movement of the clutch to get home home.
We tried to bleed the whole system tonight but by the end of it we were not even getting a dribble from the bleed nipple .
There was no sign of leaks anywhere although there is now most of the contents of a bottle of fluid over the drive (the easy bleed is a pile of poo)
I am guessing the clutch master cylinder has gone. Would this be a fair guess?

Sounds like it. I think they are quite cheep as well.

Is the drivers footwell mat wet with clutch fluid?? - this is the usual sign of a master cylinder faliure.... might be the slave cylinder instead.
Get a big Syringe.... much better at bleeding a clutch than a eazi bleed kit!!!

no sign of leaking anywhere that I could see :shock:

It could be a flexi hose that has delaminated on the inside so blocking the flow. Else you could be right and that the MC has bitten the dust. I would think the latter.

I was thinking of the slave cylinder :roll:

If replacing just one cylinder it is worth replacing both and the flexi-hose as well.
In the past I have replaced just the worn cylinder only for the other one to fail quite soon after (I don't mean days or weeks but within a few months). The exact reason for this isn't certain but it could be something as simple as both cylinders are the same age and therefore have worn equally or that the increase in pressure is enough to make the old cylinder fail? Don't know the reason but twice now I have suffered this and have taken to replacing the lot in one go.
This isn't the problem you may think it is, I did my 90 a couple of years ago and it was all done in about 1 1/2hrs start to finish and the cost of the other cylinder & hose is negligable.
Regarding the Ezi-Bleed, I did without one for 20-odd years but having bought one about 6-years ago I am converted. They make an easy job even easier & quicker without the need for a second person (usually get away with letting the clutch self-bleed anyway).

When using an eezibleed it says in the instructions to connect it to the spare tyre. If the spare is inflated to a useable pressure it will blow all the seals on the eezibleed and you get fluid everywhere. I keep an old innertube out of my old fiat panda for connecting to the eezibleed, you only need about 5 psi in it for a good dry bleed.

Turns out it was the slave cylinder sticking and this had caused a seal on the master to go as well :shock:
Thanks for comeing round to do it for me Pete (sub90). It would have taken me days n days n days to sort all that out :roll:
