BRAKE PEDAL "HISS"

I WAS JUST WONDERING IF ANYONE MIGHT KNOW WHAT IS CAUSING A "HISSING" NOISE WHEN I DEPRESS MY BRAKE PEDAL? IT ISN'T VERY LOUD AND IT DOESN'T INTERFERE WITH MY BRAKING ABILITY, BUT IT DOES SOUND LIKE IT IS COMING FROM UNDER THE DASH AREA ? , AND I WOULD LIKE TO KNOW WHAT THE PROBLEM IS SO I CAN FIX IT. ANY SUGGESTIONS OR FIX IT IDEAS WOULD BE GREATLY APPRECIATED GUYS.

Can't fix it, replace it. Ballpark is around $100, core is $25.
Hey, next time you post can you hit the Caps Lock key? Thanks!
