Loud Air Sound When I Hit Brake

10

Asked by Oct 26, 2014 at 08:03 AM about the 1999 Pontiac Grand Am

Question type: Maintenance & Repair

I got new brake pads, had my brakes
bled, new brake lines, changed the
master cylinder and STILL I hear loud
air when I hit the brake pedal. It even
does it if my car Is off. My brakes also
go all the way to the floor? They won't
stop neither and even in park or at a
red light my cars RPM shoot up with
out even hitting gas. I'm tired of trying
to figure out the problem can anyone
give me advice? I have a 99 Pontiac
grand am

This is brake booster and uses a lot of vacuum. If vacuum hose has come off you will hear a massive vacuum leak,---'air sound'-- image will size up

the booster has a diaphragm that could be ruptured, inside

Okay do u think all I need to do is replace the whole booster and it will be good to go?

Well can't say that for sure.. a failed booster would not cause brake pedal to go to floor.... you will still have brakes but not with vacuum booster assist. Was only addressing the 'air noise'

I can understand your frustration... sorry I was no more help but a vacuum leak can cause the engine to rev up as you describe

Check and make sure your booster vacuum hose house running from your intake to your brake booster is hooked up and doesnt have any cracks in it.
