Without the bleeder nut, you would not be able to bleed the caliper completely as that is the highest point.

One way of bleeding it is to remove the caliper from its mount and loosen the hose. Get someone to sit in vehicle and depress the brake pedal slightly to prevent fliud from returning to master cylinder. Turn the caliper so that the hose is at the higest point and use a G-clamp to slowly press the piston backwards and allow the air to be bled from the caliper. You might need to repeat the process a few times.
