      Because of the prevalence of disc brakes, power-boosted braking systems now come standard on nearly all new automobiles and recent-model used vehicles. Disc brakes are not self-energizing like drum brakes, so they require a power brake booster to keep pedal effort reasonable for all drivers. 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 a car. The high, hard pedal and longer stopping distance mean you are not getting power boost.
