Unhappy still having bleeding problems...Help

Okay...we changed the slave cylinder and used the oil can method to bleed...was going great at first...bubbles came up and then just fluid, when all of a sudden fluid stopped coming up and pressure bubble formed in hose from oil can...husband determined that fluid was reaching slave cylinder, but not clutch master and changed master and supply hose in case bad, or blocked? So, tried to bleed again, but same thing...pressure bubble in hose from oil can, and still no fluid coming up in resevoir...BUT hydrolic fluid reaching master if forced from above, but neither way, going all way through.....HELP!!!!!!

Seriously try the method I mentioned in the other thread
I pissed around with m w108 for ages before trying it
Ive bleed brakes and clutches more times than I can count and this is by far the easiest way for a difficult clutch
Even if the master is stuffed it will still purge all the air

I have had sucess bleeding the clutch with the brakes. I run a hose from the bleed screw of the front caliper over to the bleed screw on the slave cylinder and gently push the brake pedal. Keep an eye on the resevoirs. The clutch wil overflow and the brake master will get low. I have used this method on my 113, 114, 115, 123 cars. (even a Honda!)

loosen the hose under at pipe that goes into car , see if brake fluid comes out of there when you pump oil can , if it does , unbolt the rod at top of master to brake pedal , do it again . if it work , the pedal is pushing on the master piston and closing the reservoir access . make sure your oil can works . this method is the best / most simple .
