Replacement Quick Exhaust Valve for Roadmaster BrakeMaster Supplemental Braking System

Question

Question:

Ive lost the valve at the bottom of the actuator cylinder. Where can I order this part? I am not missing the valve, only the insert with the pressure relief function. Apparently this part threads into the valve bonnet and somehow came unscrewed. Can one purchase just the insert?

The replacement valve that you will need is # RM-450601-50. This is the replacement exhaust valve for the Roadmaster BrakeMaster system.

The valve is a complete replacement. There is no rebuild kit or separate parts available for the unit.

You can use an isolating diode kit like #48955 to prevent tail light back-feeding in your flat towing set-up. Each stop and turn circuit (4 in total) will need a diode to allow signals to travel in only one direction, without back-feeding to the RV.
