Just replaced my acutator with the Dexter. Looks very good quality. Works great. I bled the brakes by getting my wife to activate the manual control of the in cab brakecontroller. Open the bleed valve until good clean fluid comes through, close the bleed valve and have your second person stop activating the switch. Move on to the next one. Start in the back and work forward. Use a brake bleed clear hose and container to keep from making a mess. Make sure your brake lines are in good shape. I had to replace all mine. Make sure wiring is of the proper guage. I had to upgrade these as well.
