How to perform an operating check on the power brake booster?

To perform an operating check on the power brake booster, begin by depressing the brake pedal multiple times with the engine off to ensure there is no change in the pedal reserve distance. Then, depress the pedal and start the engine to see if it goes down slightly, indicating normal operation. To check air tightness, turn the engine on and off. Depress the brake pedal and check if it lowers farther the first time but gradually rises after the second or third time.
