InvisiBrake - is currently on backorder. You may still purchase now though and we'll ship as soon as more become available.

The Roadmaster InvisiBrake is a fully-automatic, progressive 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 (8¾” x 8¾” x 2¾”) 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.

Bypasses the 12-volt outlet and charges your battery

InvisiBrake connects directly to the towed vehicle’s battery and constantly 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 full-time (‘active’) power 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

Average installation time — 5 hours
