How do you know if the booster is bad? Is there other year trucks that I can swap it out with. My truck is 1971 3/4 ton 4x4.
Sounds like your booster is bad. check your vacuum line and make sure it's working.
Next step on the pedal and start your truck.....if it drops your pedal it good, if not it's BUTTCO.
