Hey Shannon ,I'll ask a lot of questions and hopeful you may see a problem, did you bench bleed the master before mounting it on booster ? next bleed wheels from the furthest point away from master ,right rear first ,left rear second right front next and left front last , you can buy auto bleeders from most auto parts stores just crack one open and there one way valve inside won't let air back in and you leave them on when done just tighten ,7 bucks each. next do you have E brake on ? at some point try starting truck and pump the brakes SLOWWWWWLY full strokes .and make sure master never goes empty , and some times ABS proportioning valve can give you a had time .
hope this helped ,good luck .
