wishminewasanss Posted March 30, 2008 Report Share Posted March 30, 2008 So I jump in my truck today to leave to the mall with my sis, and I take the parking brake off and I press my brake pedal, and I hear a noice like air is passing through. And the weirdest thing is that while iam pressing the brake pedal my rpm's just drop to below 1000 and my truck wants to shut off. Iam planing on taking it in the dealer 2Morrow. Any suggestions or help would be appreciated on us wrong , thanks guys. Quote Link to comment Share on other sites More sharing options...
desrtrat Posted March 30, 2008 Report Share Posted March 30, 2008 sounds like maybe the break booster diaphragm went out. a couple years ago i towed a 04 silv that it happened to them while doing75 down the freeway. good luck Quote Link to comment Share on other sites More sharing options...

brobradh77 Posted March 31, 2008 Report Share Posted March 31, 2008 POP the hood real quick and check the grommet. Its a $7 piece if thats broke. Quote Link to comment Share on other sites More sharing options...
wishminewasanss Posted April 1, 2008 Author Report Share Posted April 1, 2008 So I took my truck in today, and it turns out it was my whole brake booster assembly. That's why my brake pedal was making a swooshing sound! And also my check engine light came on and that was the result of my fuel pump was no more. So it is all taking care of, all covered in warrantty so no worries! Well the only worry is waiting to get my truck back . Iam picking her up 2Morrow, so thanx guys for helping and replying.
