During an emergency stop in a school bus equipped with ABS, what braking technique does the AAMVA manual direct the driver to use?

AAMVA CDL Manual, Section 10.6.3 (Braking with ABS), p. 10-9

A driver trained on older, non-ABS vehicles may instinctively pump the brakes in an emergency, which can actually interfere with how ABS manages wheel lockup. Knowing to brake normally, without pumping, on an ABS-equipped bus is a specific, test-relevant behavior change from pre-ABS braking habits.
