Q:When part goes bad is there an air leaking sound heard inside when applying brakes?
A:The primary symptom of power brake booster failure is a high, hard pedal that requires greater than normal pedal pressure to stop the car. You may also notice that it takes a much longer distance than normal to stop your car. The high, hard pedal and longer stopping distance mean you are not getting power boost. If the rubber diaphragm is bad it will lead to vacuum leak. A properly functioning power brake system should provide power assist on first application of the brakes every time, with normal pedal travel, pedal pressure and stopping distance. However, if your brake pedal is low, spongy, requires pumping or fails under steady pressure, the brake booster likely is not at fault. These are indications of other serious problems in your braking system that require prompt attention.
