Brake pads have what they call "sounders" small metal tabs that when the lining gets too a certain wear point they contact the rotor and make a squealing sound, telling you it is time to check the brakes, the air sound could very well be the booster unit has deleloped a vacuum leak in the shaft seals, if this is ture then you will have to replace the booster, it might be cheaper to replace the complete booster assembly than just the booster, your parts supplier can help you decide what would be the most cost effective.
