hey guys just recently when the car is running and i press on the brake and let off i hear a noise coming from the brake pedal. the noise sounds like and air leak or hissing sound. it goes away when i press on the brake pedal but comes back when i let off. do you guys know what the problem is and what needs to be replaced? and also maybe a diy?? thanks

 

THe brakes are VACUUM ASSISTED< ie air, Enjoy, woody

WEEKEND OH YEAHhhhhhhhhh

 

Sounds like you have a vacuum leak in the brake booster. With your foot off the pedal, no vacuum should be leaking.

I think I know the noise he's talking about, mine have done it since I've had the car and they work fine. Nothing needs to be replaced lol

 

thanks for the help guys. so does that mean i have to get a new brake booster to fix the problem???

 

I had something like this once and it was a vacuum leak, the dealer replaced the power brake unit.
Pinpoint the source of the noise under the hood.
