To properly bleed the slave of any trapped air, the slave Push Rod needs to be temporarily removed or disconnected. The slave piston needs to be moved outward until it was flush with the end/edge of the cylinder. Without moving the piston outward and pumping fluid into the slave cylinder, air will be trapped behind the piston.

Have someone depress and hold the clutch pedal while you're laying under the car with your thumb on the piston to make sure it doesn't pop out. While the pedal is still to the floor, crack open the slaves bleeder port and slowly depress the piston into the cylinder. Once it bottoms out, tighten the bleeder. Have your helper let off and again depress the clutch pedal, repeating the same procedure a few times. While the bleeder port is open and you're slowly depressing the piston, rap on the side of the slave with a box end wrench to hopefully untrap any air bubbles.

Master/Pedal adjustment:

The clutch pedal needs to be set to its highest point. Connect the clutch master linkage to the pedal making sure the master cylinder is fully extended. The linkage can later be adjusted (shortening the linkage) to change the point where the clutch engages/disengages if you want to fine tune it.
