Here's some info from the UFP guy on BassBoatCentral.
"On the bottom of the actuator you will see where the brake release lever hangs down, just behind the ball socket. Just to the rear of the L shaped release lever is an access hole for a screwdriver. Insert the screwdriver until you hit the pushrod, then angle it toward the front of the trailer, about a 45 deg angle and you will find the end of the pushrod. Hold up on the brake release lever with one hand and push the pushrod back toward the trailer by simply cranking your wrist. You can pump up the brakes this way very easily. Once you get a few strokes in, let go of the release bracket and stroke the pushrod once more. It should lock in place. Go to the rear and open the bleeder on the caliper and relieve the pressure and any air, close it, go back up front and push up further on the release bracket and it will again spring up and down, starting the process all over until bled. Remember to lower the nose of the trailer before bleeding. Air bubbles travel up and will naturally migrate toward the rear, aiding in a quick bleed."
