We have a video that will be very helpful for you (see link). To bleed the brakes start at the rear most axle and the wheel closest to the T in the brake line. Open the bleeder valve and attach a hose that you run into a clear bottle. Fill the master cylinder with the proper brake fluid and then activate the trailer brakes until the fluid runs without air bubbles. Your model may have a lever or a place under the coupler to activate the brakes with a wrench. If your actuator does not have another option you will need to manually move the coupler, where the ball attaches, to activate the brakes for bleeding. Once you have the first brake bled go the the other brake on that axle and then work forward always starting with the brake closest to the T in the brake line.
