Troubleshooting Roadmaster Invisibrake that Shows Zero Pressure
Published 11/09/2015 >
Question:
What causes the invisible brake to loose the air pressure I after setting it. Can stop the motor home for 10 minutes and the pressure will drop.

Expert Reply:
Are you sure the pressure is being lost and not actually maxed out? If the air pressure of the InvisiBrake part # RM-8700 is set to the maximum the gauge will actually spin completely around the gauge and show zero.
To confirm that the compressor is operating properly, pull out on the brake pressure adjustment knob and rotate it counterclockwise. The needle will move as you lower the pressure. Adjust to desired pressure setting.
