Roadmaster - Invisibrake - 8700

InvisiBrake is a fully-automatic supplemental braking system that uses the electrical connections already in place on your towed vehicle (the towed vehicle's electrical harness) to brake when you brake the motorhome — the same electrical signal that activates the towed vehicle's brake lights also activates InvisiBrake.

 Completely out of sight — InvisiBrake is so small (8" x 8" x 2") it can usually be mounted under the driver's seat, under the rear seat, behind interior panels or in the trunk, without sacrificing any of the vehicle's usable space.

• Set-it-and-forget-it braking — Once it's installed, InvisiBrake just works. There's nothing for you to remember — not even an on switch. Just plug in the umbilical cord like you always do and you're ready to go!

• Charges your battery while towing — InvisiBrake connects directly to the towed vehicle's battery and trickle-charges the battery during towing — InvisiBrake will never drain the battery.

• Two-stage motorhome monitor — InvisiBrake includes an LED monitor for a visual reference of braking activity; an audible alert at the motorhome will warn you if the brakes have been on for too long.

• Activates only when the motorhome's brake lights illuminate — no false braking!

• Energizes your power brakes — most braking systems work on a 'dead' brake pedal. InvisiBrake energizes your power brakes so that you have the same power braking system while towing as you do while driving.

• Works in virtually any towed vehicle with vacuum-powered brakes — including hybrids and those with 'active' (or 'continuous power assist') braking systems. 

• Includes an emergency break away system

• Easily adjusts to individual braking preferences — braking pressure is adjustable from five to 100 psi.

• Meets U.S. and Canadian braking requirements
