How should a rider operate the brakes on an Anti-Lock Braking System (ABS) equipped motorcycle during an emergency stop on wet pavement?

1. Firmly and continuously squeeze the front brake lever and stomp the rear brake pedal simultaneously, maintaining steady pressure throughout the stop without pumping the brakes
2. Rapidly pump the brake lever on and off five times per second manually
3. Avoid using the front brake completely because ABS only works on the rear wheel
4. Immediately turn the ignition key off to let the ABS computer take full control
