Setting Adjustment Level of Roadmaster Inivisibrake

Published 07/10/2019

Question:

My motor home is 18,000 empty,pulling a Fiat which is 2,300 lb. What am I looking for to know Im in the ball park on adjustment. I have pulled a travel trailer before and could feel the trailer braking at stops. And I can see the Invisi brake is working when wife steps on RV brakes and Im under dash of Fiat, but dont feel it when Im pulling it and I stop.

The braking pressure that the Invisi-Brake System # RM-8700 that you referenced comes from the factory set at is the most universal setting that works for most applications, 60 psi.

You will want to test your setup using the preset setting and compare the stopping power to how the RV stops without a vehicle behind it and adjust as necessary. It sounds like you need to increase the setting so that it applies more braking power.
