I also get the hissing sound in my GP.. No problem at all...
If you do so the pedal will became hard & you can not able to pump the pedal any more.
All this hissing noise that one hears in a FIAT is because the vaccum booster is placed just under the dashboard above the pedals.
Even i had this problem but mechanics say, its normal. It vanishes when brake pedal is pumped. I was fearing problem in brake master cylinder. But now im used to it now.
I can hear the sound whenever i press the brake pedal, even while on the move. The hissing sound comes from the back when I release the brake pedal
