Trouble bleeding 1996 Z28 clutch

I just replaced the clutch master cylinder in my Z28, and I need to bleed the air out of the system, but there isn't a bleeder valve. I thought it might be possible the system bleeds itself, so I pumped the pedel for like 30 mins and that didn't work. I have a feeling I need to pump the slave cylinder but I can't get it off as I can't find my 13mm deep socket. If anyone knows how to bleed it the help would be greatly appriciated. :)

yeah, the slave should have come with directions on how to bleed it. I do not remember the specifics, but i am sure you can do a google search and come up with something.

did you remove the master cylinder filler cap before you started pumping the pedal?
