87 k10 trouble

[74 shortbed 406]

I changed the hubs, and brake pads and rotors, packed the bearings all while I was doing this and it took about 2 1/2 hours. Got it all back together and didn't like how the clutcvh was feeling so wanting it to work better and knowing it was a hyd clutch I went to bleed the line. Broke the bleeder on the slave cylinder and got some air out of the line and know the master cylinder won't build pressure. I took line off of intake side(line from reservoir) just to see if line was blocked, it wasn't. Broke the steel line off of other side and it doesn't build enough pressure to push finger off(put finger over hole to pressurize). So mon I am buying a master cylinder for it.
