Hi there,

this sounds like you brake booster has failed, the sound is vacuum leaking from the servo chamber, Brake booster use engine vacuum to assist with breaking effort, Quick test. Remove large hose going into brake booster (plug this hose or the engine will not run very well) and apply brakes, noise will be gone. Do not drive with booster disconnected as brakes will be very heavy and inefficient.
