Final answer:
Technician A is correct that an ABS will pulsate the brakes during hard stops, while Technician B is incorrect that ABS brakes are only found on imported vehicles.
Step-by-step explanation:
Technician A is correct. During hard stops, an ABS (Anti-lock Braking System) will pulsate the brakes. This is achieved by rapidly applying and releasing the brake pressure to prevent the wheels from locking up and allowing the driver to maintain steering control.
Technician B is incorrect. ABS brakes are not exclusive to imported vehicles. They are a standard feature found on many modern vehicles, regardless of whether they are domestically produced or imported.
Therefore, the correct answer is A) A only.
