Description
Roadmaster 8700 InvisiBrake is a permanently installed, fully automatic supplemental braking system for compatible flat-towed vehicles. It uses the existing motorhome-to-towed-vehicle lighting connection to activate braking when the motorhome's brake lights come on. Once installed, there is no portable brake unit to place at the driver's seat for each trip.
Function and fitment
- Progressive braking increases applied brake force with the duration of the braking signal; it is not the same as a direct proportional air-brake system.
- Uses the towed vehicle's power braking assist and supports many vacuum-assisted or active-brake vehicles. Verify the exact vehicle using Roadmaster Fitmaster before ordering.
- Brake pressure is adjustable from 5 to 100 psi according to Roadmaster.
- Includes the emergency BrakeAway system and a two-stage motorhome brake monitor with an audible over-braking alert.
- Roadmaster identifies a battery-maintenance connection through the installed towing electrical system.
Installation and identification
Roadmaster estimates initial installation at approximately 3–5 hours, not 30 minutes. Professional installation and the vehicle-specific wiring instructions are recommended. A second-vehicle reinstallation kit is Roadmaster 98700; the second-motorhome monitor kit is Roadmaster 98850.
