Clutch master cylinder
 

So I hate cars. this morning my GF's Jeep seized up. So I took her about 40 miles to work. after I drop her off my clutch looses all pressure and won't disengage. so I rev matched it over to my closest friends and try and bleed the clutch. I'm getting nothing no air no fluid. So now this is our only vehicle, and its one thing after another. sorry about the rant. But I did drive 60 miles with out use of the clutch. I did manage to get pulled over. First time being pulled over in the seven. some day...

reservoir is full and when I press the clutch fluid level rises, rather than dropping. also air bubbles pop up. I see no leaking and no fluid or air comes out when I bleed it. clutch is not stuck to the floor it just doesn't have any pressure. another thing is I've flushed the reservoirs out twice and keeps coming back muddy. I've ran like 3 large bottles through it and still couldn't get it clean.

Is this a master cylinder problem or something else? I've had hydraulic issues before. but it was a lot more obvious. At least I'm fairly sure the throwout bearing isn't seized. I will replace both master and slave don't need to mention that.

Car is an 83 GS and Has a stainless clutch line also not leaking.

I would suggest taking both clutch master and slave off, tearing them apart, polishing the bores, put in new seals, then you are done...

Sounds like a slave to me, since it's your only car at the moment, the slave would probably be much easier to access and rebuild, and based on what you're describing the master is probably still good. Sounds like the slave froze up, you may be able to rebuild, but a reman slave with lifetime warranty is only like $20 at advance auto parts. Pull the slave off, back the bleeder out a few turns, and see if you can move it back and forth by hand. If it's jammed, get a new slave, else check the master. I doubt both will be bad unless they have been sitting for a long time with no fluid.

[edit] And it sounds like the cars hate you, too! haha

I figure if I do both maybe it wont brake down next week. and they both have lifetime warranty

Well I replaced both master and slave on Monday. All is working well. and I have a lot more peddle feel. it was mushy before. but here's a quick write on how I did it.

Slave

remove clutch line from hard line
remove 2 12mm bolts holding it in
use clutch line to maneuver it around the rats nest and try and keep the bolts in the holes
pull it out
swap the clutch line to new slave
put the bolts in the holes
use clutch line to maneuver it back and place
I found it easier to get the top (towards passenger side) bolt threaded and then the other bolt
torque the bolts down

Master
remove hard line from master cylinder
remove the pin that connects master to the clutch peddle (there's a collar lock)
remove the 2 nuts
slide it out
and install is exactly opposite and easy compared to getting it out.

connect hard line to clutch line and bleed the system.
