  1. @5t341tH any brands you'd recommend? I've been looking at the Centric ones on Amazon.
  2. @banzai510(hainz) thank you, I did try it, and still no success. However I think I found the issue... I managed to get both ends of the hard line off and blow through with compressed air so I know that's not obstucted now. After that I blew through the lower line leading to the slave cylinder and out the bleeder valve, then filled the reservoir back up and tried pumping again, STILL no flow. At this point I am fairly confident it is the master cylinder that is the problem, so I drained it, pulled the line back off and unscrewed it off the firewall and this is what I found... This is the same type of "gunk" I mentioned earlier that was in the resevoir when I first pulled the truck out. The "plunger" (? Part attached to clutch pedal, not sure what the actual name is) is loose and doesn't produce any "pressure" when pushed in and out like I would imagine it should if it were functioning properly. So I'm guessing this is the issue, any thoughts guys? If I'm replacing the master cylinder now should I also replace the slave cylinder?
  3. Thanks for the help everyone! I drained out the master cylinder, blew through the hole with compressed air to see if i could loosen whatever the clog is. Also blew out some gunk blocking the bleeder valve since there was no cap on it. Filled the master cylinder and tried again, still no luck. I am now trying to disconnect both ends of the hard line to blow that out as Stoffregen suggested but man those tube nuts do not want to budge, i sprayed them yesterday with some liquid wrench to try and free them up but they still won't budge, I am afraid of rounding off the edges and then really being screwed. Does anyone know what size the nuts on the hard line are? Seems just a hair bigger than 3/8s but I'm assuming it's metric.
  4. Hello Ratsun! First time posting! I recently acquired a '76 620 that had been rotting away in a field for the last 20 years in eastern Oregon. Suffice to say it needs a lot of work and I have decided to make it my first project car since I am covid-unemployed and have lots of time on my hands, and I've always wanted an excuse to start working on cars... I am fairly clueless when it comes to working on cars but I have been perusing older threads and picked up the Haynes manual, so please bare with me if I'm making an obvious oversight. The problem I am having right now is I am trying to bleed the clutch because the pedal gives no resistance, but it is not working. I opened the bleeder valve 1/4 turn, attached a hose going to a bottle with dot-3 and started pressing the clutch in and out 40 times or so to see if any bubbles would come out, but no bubbles. The fluid level in the clutch master cylinder didn't go down at all so I don't think the fluid is cycling. Could the lines be clogged? The clutch master cylinder was bone dry with some dried gunk in it when I pulled the truck out. If anyone has an idea what the issue might be, I'd love to hear it. Thanks!
