"92" Hydraulic clutch problems

Hello I'm having problems with the hydraulic clutch on my 1992 accord ex. 2.2 ltr. 5 speed manual (duh)
I was loosing pedal and checked the reservoir I found it dry when I bled the system with fresh fluid I discovered a leak on the slave cylinder push rod boot. I repaced the cylinder with a remanufactured one. That's where the problem I'm having started, I cant't seem to bleed the system or even to get it to build pressure of any kind. There is fluid getting to the slave weakly but the pedal constantly bottoms out and stays in the depressed position. I tried pumping the pedal by hand, no help. I pulled fluid through the line with a vacume pump full stream, no help. I got my Son to press the pedal and attempted to bleed again, but all I get a dribble or very weak stream at best. I, m wondering if the slave cylinder I bought is defective? It's hard for me to believe the master cylinder is bad considering it was working fine with the leaking slave (pressure wise). Do you have any advice for this situation?

Thanks in Advance
