on the slave cylinder on the passenger side of the truck there is a bleed screw. you crack it open and a helper in the truck pushes the pedal to the floor, then close the screw. let the pedal up, and open screw, pedal down, tighten screw
continue this til all air is gone, and know this, when you push the pedal down do not let it up til the screw is tight or air will go right back in
and afetr you do this 2-3 times check the flid level and do ot let it get empty or air will go in and you have to start all over
good luck
