Jorge, since the Demco Drum Brake Actuator # DM28CV doesn’t include a built-in lockout, you can install a manual lockout with kit # DM93CV. This is easy to install without tools, and will do a good job of preventing the brakes from engaging so you can reverse the trailer up or down your steep driveway.
What kind of trailer do you have?
