Will the Roadmaster InvisiBrake Release Air Pressure Over Time When Disconnected from Motorhome

Updated 04/15/2019 | Published 04/12/2019

Question:

Another question - Once our car is disconnected from the motorhome, should the pressure read 0 on the invisibrake monitor or does it continue to hold pressure for a time and eventually back to zero?

The air pressure in the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 will slowly release the pressure until it is down to zero when you disconnect your 2017 Ford Focus from your motorhome. It won't drop all of the sudden once disconnected. I reached out to my contact at Roadmaster who confirmed this.
