Do Demco Brake Actuators Ship Pre-Bled And Ready To Go, Or Do They Need Fluid?

Question:
Is this actuator pre-bled and ready to go?
asked by: Trevor
Expert Reply:
Trevor, all of the brake actuators, including the Demco Drum Brake Actuator 8,600lbs # DM78CV, ship dry to prevent fluid leaks during transport. You’ll need to fill it with DOT 3 or DOT 4 brake fluid and bleed the system once installed.
It’s a quick job if you have a buddy and a brake bleeder. I attached a demonstration video along with a help article that covers this topic. If you need any assistance or have any other concerns, feel free to drop a comment on this page! :)

Hey Trevor, did you get a chance to fill and bleed the brake actuator with the DOT 3 or DOT 4 fluid? I'm curious to know how it went for you, as it could really help others in a similar situation!
