Demco DM72VR Brake Bleeding Instructions and Hopkins 7 Pin to 6 Round Demco Actuator
Published 07/14/2021 >
Question:
Hi there, I recently purchased all new brake components for my boat trailer from etrailer, and by the way, great customer service/support! I need so instructions on how to bleed the brakes. The Demco actuator is P/B DM72VR, and Im using Demco drum brake assemblies, P/N 18788 and 18787. Also, I purchased P/N A10-6034VP, to allow me to wire up the electric reverse brake solenoid. I need a long coiled cord that goes from round 6 pin trailer to a round 7 flat blade vehicle side. What do you recommend?

I have attached a link that will give you step by step instructions on how to bleed your trailer brakes.
For your 6 pin trailer connector to your round 7 flat blade vehicle connector I recommend the Hopkins Heavy-Duty, Coiled Trailer Connector Adapter item # HM47085. This cable stretches out to 3' when it is uncoiled.
