Sounds like the pads are worn out and are grinding on the rotors. You will likely have to replace the pads and rotors.

If it is a constant hiss with your foot on the pedal, you have a bad brake booster. If you hear a hiss, and nothing else while holding the pedal, it is the air escaping from the booster boot, and should not pose a problem.

you mean you hear air in the cab down by the pedal. If thats the case your power steering assist is leaking. Its the big black unit behind the brake master cylinder. It may set a check engine light at times for lean condition.
