Have a 03 F150 4.6l 2x4 and recently, meaning now, changed out rotors and pad along with the hardware. Problem I am having is that boot covering the sliding pin either traps air and bolges the boot out or when I break the seal all air is out. In that matter when sliding pin is extracted some the boot sucks the inward. Anyone know if there should be air trapped or sealed to hold none?

Should right itself all bolted up. The vacuum is created by the grease on the pin. It's likely you have too much grease on it. All you need is just a smidge to allow the pin to move.

^i agree it's just a vacuum effect from the pin moving and probably too much grease
