My brakes are almost non existant you can push them to the floor and still not stop on a dime or anywhere near it for that matter. You can hear a sound inside the car an air woosh if you will when ever you hit the brakes no matter what speed you are going! Whats wrong with my brakes I thought maybe the brake booster am I right?

Did you have to fill your fluid sometime recently? If not I believe you need a brake booster, because there is definitely some air in your system. Do you have abs?

You need to check your master cylinder remove it from the booster and look for any leakage on the back sideof the master cylinder. The booster is fine if there is still power assist when the vechical is running. The noise may be from too much from the master cylinder

If you have abs, there is a problem with the abs module, I believe its the pressure switch. Its faulty, you will have to have it looked at.
