Clutch Slave Giving me HE11

[Sam]

Guys, I'm Nearing getting my buggy back together, down to electrical (temporary, so I can run it a few times before powder coating) , and getting the darn clutch bled....
Last time I ran the buggy I was having to pump my clutch even after bleeding it and even then it wasn't good. So I bought a new slave cylinder from speedway. Anyways, After bleeding and bleeding I'm still getting some air, and the slave wont even try to move, even when it is sitting free. Is my master cylinder bad or what is the deal?  I have bled slave cylinders lots of time and never had any trouble.
Where should I start? Master is a 5/8, slave is 7/8. My old slave was 7/8 also.

Change the m/c. I just went thru the same crap with my drag car this year.
I swapped out the m/c and am now good to go.

Thats what I figured. I just got nervous when I was reading about all the folks that spend hours bleeding their slave, never has taken me more than 5 min or less.

What hydraulic clutch set-up? I have found that my SACO aluminum MC has a short life (about 8K miles...less than 2 years of street driving). I recently rebuilt it but I am not confident it will last too much longer.

Latest Rage!, It lasted 6 years! So I just ordered a new latest rage master. Installed it today and works like a champ, I will admit that the 3/4 master and speedway 3/4 slave works better than the 5/8 master and latest rage 3/4 slave ever thought about working.   The speedway slave was only like $29 and rage master was $36
