SMI Airforce One and Roadmaster Brakemaster compatibility

September 02, 2024, 11:00:14 pm

I recently purchased a Dinghy that came equipped with the Brakemaster 9000 supplemental  brake system.  My U320 is equipped with an older Airforce one system. The air connecting hose from coach to toad is the same for each system.  I have not fully researched this but it appears that both systems on the  RV side connect to  a port on the air brake relay valve. Does any one know if they both connect to the same port?  If so this would save having to plumb the RV side.

The toad side of the Brakemaster 9000 is just like the AirForce One with the exception of how the cylinder actuates the brake pedal.  AF1 pulls the pedal from the firewall and Brakemaster shoves the pedal from under the seat.  They both receive proportional air from the coach braking system.  If you have any doubts just have someone in the toad and watch the pedal while you actuate the coach brakes.  If they installed the LED light, I have found it worthless in daylight.  Both systems had options for hydraulic brakes to proportional air but you don't need to worry about that conversion as U series are all air brakes.
