The problems persist after numerous attempts to bleed the hydraulic system ,I still have no clutch pressure and the realization is I need the master and slave cylinders replaced.I located the parts numbers but I want to be sure, I've only used my epc a few times.

And could someone recommend a supplier or any other direction I could take .
thanx

Unless you have large amounts of fluid in the bell housing, your slave is probably OK; although, if you're doing one, you might as well do the other, too.

Scott,
The parts are pretty pricey. Europa normally has them in stock, but it is over $400 for the pair. Depending on the currency its about $150 for the slave and about $250 for the master. Mark (Inkblotz) recently found a slave cylinder from a more common Mercedes that crosses. I believe it was from an early 80s 240D. It was much cheaper and more readily available. Hopefully he will chime in. I dont remember anyone finding a cross for the master cylinder, but maybe someone will. If you dont need it right away (perhaps you have another vehicle) I'd try Sean (Eurotruck) in GA. He's on this forum.
I hate to suggest it, but maybe try a pressurized "back bleed". For this one you open the bleeder screw on the slave, firmly attach a hose (like with a wire tie as a clamp) and then force fluid backwards through the system up to the master cylinder.
Sometimes this way will dislodge a bubble that was trapped while bleeding the normal direction.
Another place to look is inside the bulkhead where the pedal rod comes through from the MC. If you see any fluid there, it's the MC.
It might also work to just disassemble and thoroughly clean the master cylinder. I did that for a guy who had your symptoms a few years back. The fluid in his reservoir was black and cruddy and full of little rubbery chunks. One of those chunks had lodged in the seal preventing full pressure build up. The seal itself was fine though. If your fluid is gunky like that, a good cleaning with denatured alcohol might do the trick.
Check the prices again, but last time I did, a rebuild kit was not cost effective, it was only a few dollars more for the whole assembly, and that of course got you a new cylinder bore, which can be a part of the problem. Though if you went the cleaning route first, you'd know the condition of your bore for sure.
And don't discount the other poster's reference to the flex line. If I was going to the trouble to do new master and slave, I'd certainly do teh flex line too.
These folks can be pricey, but their solutions are excellent.

I purchased the Clutch master direct from the local Mercedes Dealer (they happened to have it in stock). The part number is A 001 295 8006 I got a good deal at the time $141.44. The regular price was $262.47 from the dealer. Sean's price @ Eurotruck was about the same maybe a little less. I would have bought it from him but he was out of stock @ the time. I will do some looking into the slave cylinder. That part was fairly generic to many Mercedes I believe the 240D was on the list. The main thing to look for was the bolt pattern they were not @ 12:00 and 6:00. It was more like 12:00 and 5:00.
I just came from the dealer and he confirmed that he had the available part #s in his system but that he would have to contact Germany to verify and order it(4+ days)[:(] $226.24 master cyl
Mark, I checked your previous post about the 240d slave cylinder interchange but I was under the impression it would only work for your 5 spd . If I could use that on my 4spd it would definitely help.
If anyone has any repair kits that would fit my setup PM me.
