Technician A says an ABS will pulsate the brakes during hard stops. Technician B says ABS brakes are found only on vehicles that have been imported. Who is right?

The statement made by Technician A is accurate. An Anti-lock Braking System (ABS) is designed to prevent wheel lock-up during hard braking, which allows the driver to maintain steering control. During such hard stops, the ABS pulsates the brakes by rapidly modulating brake pressure. This pulsation occurs to prevent the tires from skidding, enhancing the vehicle's safety and control in emergency braking situations.

In contrast, Technician B's claim that ABS brakes are only found on imported vehicles is incorrect. ABS technology is widely used in many vehicles, both domestic and imported, across various manufacturers. Thus, the first technician’s statement correctly identifies a fundamental feature of ABS, while the second technician's statement does not accurately reflect the application of ABS in the automotive industry.
