The first step to bleed the brakes is to have the Carlisle HydraStar Electric-Hydraulic Actuator # HBA16 activate so that hydraulic pressure is being made in your brake system. You can do this by having somebody step on your tow vehicle brakes while your trailer is connected. They will need to be pressing the brakes while you are performing the following steps

Starting with the brake furthest from the actuator open the bleeder screw and allow it to remain open until seeing brake fluid free of air bubbles coming out of the bleeder screw. Close the bleeder screw and move to the next brake and so on until all brakes have been bled. While performing the bleeding process, monitor the fluid level in the reservoir so that more air is not pumped into the brake lines because of low fluid level. To prevent spilling brake fluid on the ground, one end of a length of plastic tubing should be placed over the end of the bleeder screw and the other end should be placed into a container so that the fluid flow can be monitored for bubbles.

I attached a video on this also for you to check out.
