If you must make an emergency stop, you should brake so that you:

When making an emergency stop, maintaining control of the vehicle is paramount. Braking in a manner that allows for steering helps ensure that you do not lose control and can potentially steer to avoid obstacles or other vehicles. Using the steering wheel while braking gives the driver the ability to keep the vehicle pointed in a straight line, which is important in preventing skidding or rolling over.

If you were to apply the brakes too aggressively or lock them up (as would happen if you used full brake power), the vehicle could skid, making it difficult to maintain directional control. Furthermore, using the hand brake first could lead to a loss of control as well. Gradually easing off the throttle may help in some situations, but it does not directly facilitate an emergency stop while retaining steering control, which is crucial in emergencies. Therefore, the most effective approach is to brake in a manner that allows the driver to steer and keep the vehicle straight while slowing down or coming to a stop.
