Can someone please point me to a link here on the forum in diagnosing the master clutch / brake cylinder. Are there 2 master cylinders even?
Fluid is disappearing from the reservoir in dash unit (drips onto cab floor)
I have tried the wiki and I have done a quick search through the tech forum (quick? - that took an hour), but cannot find specifically an article or a how to on diagnosing which cylinder is at fault (master brake / master clutch) (Like i say, I am not even sure if there are 2 master cylinders, I thought just one (master brake) but i have seen mention of a clutch master cylinder somewhere - could be a red herring.

Have had salve cylinder (back, near gearbox) replaced last year.

Can't find my Haynes manual (was on my bedside table , now its not), and haven't found the right Bentleys manual yet.

I have seen an article on her some time ago as it mentioned that once the master cylinder replaced, I'll need to bleed the system - each wheel.

If someone can point me to that article would be most appreciated.

There are two separate master cylinders, one for the brakes, and one for the clutch. The brake master cylinder is just under the reservoir, the clutch one is just above the clutch pedal.

By taking off the instrument panel (four screws and a few plugs - fairly easy) you will be able to check the reservoir and brake master for leaks, if that all looks dry you should be able to crawl around and feel the clutch master - if you've eliminated drips from above it will be the clutch one that probably needs replacing. Although obviously check all the hoses are connected securely.

Thanks Mirams - so the one under the reservoir is the master brake one and that looks ok..
I'll get out to van again and try and diagnose a bit further
