WITH NEWER CARS, THE BRAKE BOOSTER IS MORE SENSITIVE TO CHANGES IN THE VACUUM FROM THE ENGINE, WHICH MAY RESULT IN SLIGHT VARIATIONS IN BOOSTER REINFORCEMENT / PEDAL TRAVEL. A CUSTOMER IS MOST LIKELY TO NOTICE THIS PEDAL HEIGHT VARIATION WHEN APPLYING THE BRAKE PEDAL FOR AN EXTENDED PERIOD, FOR EXAMPLE, WHILE SITTING AT A STOP LIGHT.
