clutch bleeding issues

[NC325iC]

alright well i just intalled a new master cylinder and i went and bled the system as i have in the past

-started off with a vacuum bleeder mainly just to draw fluid down through the system (with vacuum bleeding its hard not to get air bubbles)
-took the slave loose from the tranny with bleeder at highest point i openned it and pressed in the plunger and i got a nice solid column of clear blue comin out, i did this about three times each time not a single bubble comes out

i get some pressure on the clutch pedal but not enough to actuate the clutch, and not enough to push it back up.

fairly new slave
new master
fairly new soft line
original hard line

i just clamped the slave fully compressed and did manual bleeding with it like that still no dice

i had this same problem when i did my swap and i asked a buddy and he said take the slave off the transmission and push it all the way in and that will push all the air bubbles out the top and it worked great got good pressure! peddle goes down and up...o and dont open the bleeder when doing it!!

ive done every trick i could find
i ran out of fluid so i had to get another bottle and i thought id go ahead and try another slave for the hell of it, theyll be here wednesday hopefully i can get it done on thursday, im tryin to see if i can borrow someones pressure bleeder (local forum)

hmmm.....i used all old suff too, but the same thing the peddle would go down and stay down and the i did that simple little thing and it work great! but i dont know what your case could be?

so i ended up replacing the slave again, borrowing a pressure bleeder
-still didnt work
i emailed bavauto and apparently there is a brand (PEX) that they knew to be bad on other models that they didnt know they had for e30s that they sent to me, so they sent me a faulty master cylinder, so ~3weeks later on a simple MC change/new brakes job (stock rotors and axxis ult) my car finally works
