Sounds like your brake booster has an internal leak.

It's pretty easy to fix, and the wreckers should be full of them

Yea ,just got done messing with it and it's the darndest thing to tacke,would you suggest I go to the junk yard or just spend 85 dollars and replace it?

It's the only brake part that I would replace with a used one. And that's because they very rarely give any problems.

Just a guess but it's probably about $15-$20 at an autowreck. You might have to pull it off the truck for that price.
