10. A vehicle equipped with ABS has a pedal that pulsates only on hard stops. Technician A says that this is normal operation. Technician B says that this could indicate that the brake drums are out of round. Who is correct?

Explanation

Technician A is correct because as the ABS operates the triggering of the "on-off-on" of the wheel units can be felt through the system at the pedal on hard application. Since the brakes only pulse on hard application, it is not likely an out-of-round drum.
