Adapter For Vehicle Side Connector For Roadmaster BrakeMaster To BRAKESYNC Connector  


I just installed the Road master air braking system I purchased from you all. All went well until I tried to connect the air system hose from the vehicle to the Freightliner BRAKESYNC connector on the coach. I have on one side of air hose connector the female dyna con DR21-1 connector and it attaches to the Vehicle. I need the adapter that goes from the dr21- male to the brakesync female connector on the rv. See attached photos of the brake sync connector on my 2022 Fleetwood Discovery LXE 40m.

For your Roadmaster BrakeMaster System w BrakeAway for RVs w Air or Air Over Hydraulic Brakes # RM-9160, I recommend swapping out the vehicle side connector with # RM-921004-50, and then the connecting hose should work as normal with # RM-450710 on one side, and # RM-450720 on the other end.
