My brakes started making a noise when applied and the pedal goes down (not all the way) and comes back up all while making the farting noise. The truck stops but it feels hesitant some times.. It does not do this every time applied but often enough for concern............HELP PLEASE. I like to be informed before taking it to the shop to avoid being ripped off.............

Hello,

It sounds like the power brake booster has gone bad and needs replacement. Here are some diagrams (below) of how to do the job along with the new part at Amazon for 86.00 bucks. Please let us know if you need anything else to get the problem fixed. Check out the diagrams (Below). Please let us know what happens.
