When braking in an emergency stop you should?

When braking in an emergency stop, you should firmly press the brake pedal, applying maximum pressure without locking the wheels if your vehicle has anti-lock brakes (ABS). If you don't have ABS, pump the brakes gently to avoid skidding. Keep both hands on the steering wheel to maintain control, and be aware of your surroundings to avoid potential obstacles. Always look for a safe area to steer towards if you need to avoid a collision.
