Final answer:

To make an emergency stop with air brakes using the stab braking method, you should brake as hard as you can, get off the brakes when the wheels lock, and get back on the brakes when the wheels start rolling again.

Step-by-step explanation:

To make an emergency stop with air brakes using the stab braking method, you should brake as hard as you can, get off the brakes when the wheels lock, and get back on the brakes when the wheels start rolling again. This method is more effective than pumping the brake pedal rapidly and lightly or applying full hand valve until you stop. By braking hard and then releasing the brakes when the wheels lock, the driver can maintain control of the vehicle while still slowing it down rapidly.
