What always works for me is to fill the master, make sure it is fully returned, I've had to disconnect the pedal from the pushrod sometimes to do this, and then crawl under the truck and push the clutch fork and slave back(to the front of the truck) by hand slowly, bottom it out and let it slowly return to where it was resting with weight on the clutch. Do this a until you don't hear any more air in the master, then hook things back up, and 99% of the time you are merrily on your way.
That is actually Ford procedure, the shop manual calls for 10-15 cycles.
The other Ford method is plain old strange... With the slave off, it calls for removing the line from the slave, tipping it about 30 degrees, and filling it with fluid, rocking it as necessary to get all the air out, then installing it on the bellhousing.
Then you take the cap off the reservoir and have someone man the brake fluid keeping it full, and letting it run out of the line until it's clear of air, once it's clear, the you hook it up to the slave, and it should be bled... That is downright silly if you ask me.
