Hopefully , the slave is mounted outside of the bell. Unbolt the slave, open the bleeder, and tilt it in a way, that the bleeder is in the highest possible point. Hopefully, you can get it to drip Let it drip for a few minutes . If you do not have a pedal at all after this, close the bleeder, and just pump the mother 100 times . If you have to use your hand , to pull the pedal back up, do it that way . You may just start to get pressure this way . Once you have any sort of pedal, you are halfway home . Id finish up with a standard bleed, by try to not push the pedal all the way to the stop .
Good luck. I remember the frustration when I would get a tough one . You got brake fluid running down your armpits, and still cant get it to work
If its an internal slave, you can try to rig up a way to push fluid up through the system, or may even be able to force fluid down through it . Usually, there is a tiny breather hole in the cap of f the resevoir. You can use an shop air gun to slightly pressurize it, and hopefully force fluid down through .
