Buddy I would check to see if you have like a pcv valve type part between your brake booster and master cylinder as I did. I had that hissing noise and it was coming from that pcv type valve. It's plastic in my case and a hole developed in it causing the hissing noise. By the way it caused a vacum leak and stalling at idle sometimes for me. For me it was that plastic $10-15 dollar part like a pcv valve. My brakes were very very weak as if the master cylinder was going. My mechanic thought for sure it was the brake booster but dealer nailed it down to that valve. My mechanic replaced it for $10 bucks and my brakes were back again. Hope this helps.
