Success

Just wanted to close out this thread with my success, for the benefit of somebody in the future who is searching the same problem.

I replaced the hose with 8mm ID fuel hose, with hose clamps. The original braided hose fell off due to deterioration on the top mount (at the brake fluid reservour). I had to cut the same hose off at the bottom (at the clutch master cylinder) with a razor knife.

I bought a Power Bleeder, and some "Super Blue" brake fluid, and some transparent plastic line. The original fluid was brown, so I could see the new Blue fluid come out and knew that I had purged all the old fluid out of the brakes (a note on the Power Bleeder - I bought the one with the aluminum cap. Get the one with the plastic cap instead. The threads on the aluminum capped one don't fit very well, and I had to use plastic baggies as a "gasket" to get a good seal. The aluminum doesn't have any "give" to it).

After removing as much old fluid as I could with a turkey baster, I purged all 4 brake lines with fresh fluid, and checked all my brake lines for cracks and leaks.

Then after I was done purging out the old brake fluid, I connected a single piece of transparent plastic tube (1/4" ID) to two bleed nipples: one end of the transparent tube onto the bleed nipple of the passenger side front wheel, and the other end of the transparent tube onto the bleed nipple on the clutch slave cylinder that is mounted on the transmission. This connected the brake system and the clutch system into one system. Brake fluid that was bled out was forced through the clear tube and into the clutch system, which in turn forced fluid in from the bottom, forcing the air out the top (up through to the brake fluid reservour).

Then when I pushed on the brake I could see new blue fluid going through the clear tube. I played with the brake pedal and clutch pedal for a while until I thought I had fluid through the whole system. Most of my old fluid in the clutch system had already leaked out, but I probably didn't get 100% of the old stuff out. Most of it, though.

Then I closed the two bleed valves and removed the clear tube.

I put down wheel chocks a little ways away (just in case) and then started up the car and tested my clutch and brakes at slow speed, followed by a drive around the block. I just got back from some high speed runs down the interstate, and all is well.

Thanks everyone for your help and advice. Every time I do something on this car, it is the first time I am doing it, so all advice is welcome. With good advice, even someone who hasn't done something before can get the job done in a quality manner.

I hope this helps somebody in the future who is searching for a similar problem that they need to fix.

- Patrick

I, too have the same leaky braided hose. I go through bottles of Dot-4! The clutch goes to the floor about once evey other week, now. I have cut the hose back twice now, and don't have any more slack. I will buy the new rubber hose. Two things still puzzle me..... If this is the is the culprit, where is all the brake fluid? It's not on the garage floor. It's not on, or under the carpet by the master cylinder. And why is the clutch getting air the lines, anyway, if the leak is up above the master cylinder? The hose should still have fluid in it going down to the master. I can't find any other leaks from the master to the slave. Could there also be a leak at the slave going into the bellhousing?

Same hose problem here as well. I looked on the parts index and could not find one listed. Anyone got a part # for a 79 240D?

That hose isnt actually a pressure line, it's just a reservoir feed for the clutch master. If you've gotten any brake fluid spilled on any painted surfaces, make sure you clean and rinse it off ASAP. It will eat paint right down to bare metal in a hurry.

The panel under the dash has a felt pad glued to it for noise buffering, often when something under the dash leaks, ign sw (from bad shutoff) oil gauge, or clutch cyl, the pad soaks it all up until its saturated and then it begins to drip out into your carpeting. You can carefully remove the panel, I would pull the carpets first just in case, get it out then turn it upside down and rinse it out good then let it dry outside in the sun. Oil is a bit more difficult to get out.
