Frequently Asked
Questions
What is InvisiBrake?
InvisiBrake is a fully-automatic, progressive supplemental
towed vehicle braking system.
How does InvisiBrake work?
InvisiBrake uses the electrical connections already in
place on your towed vehicle to brake when you brake
the motorhome — the same electrical signal that activates
the towed vehicle’s brake lights also activates
InvisiBrake.
Is InvisiBrake a ‘proportional’ braking system?
No, it is progressive. When braking is called for, Invisi-
Brake imediately engages the brake pedal and rapidly
ramps up the braking to the setting you have selected.
What is ‘progressive’ braking?
When you apply braking force, so does InvisiBrake —
as you continue to apply the brakes in the motorhome,
InvisiBrake applies a progressively harder pressure to
the towed vehicle’s brakes, up to the setting you have
selected.
What do I have to do
to prepare InvisiBrake for towing?
Nothing. InvisiBrake works automatically when you
connect your towed vehicle to your motorhome. There’s
a motorhome monitor cord and a break away cable to
connect between the two vehicles and that’s all.
Can I switch it between vehicles?
Yes. If you sell your towed vehicle, the major components
can be removed and installed in the new towed
vehicle. But InvisiBrake is not intended to be quickly
swapped between towed vehicles, like Even Brake.
Will InvisiBrake drain the battery?
No. InvisiBrake constantly charges the towed vehicle
during towing.
Will it work in my car?
InvisiBrake fits in nearly all vehicles, including those
with full-time (‘active’) power braking systems.
How long does it take to install?
Installation, along with a brief overview given by your
dealer, typically takes three to five hours. After the initial
installation, InvisiBrake is always ready to tow, with
no adjustments necessary.

How do I know it’s working?
An LED monitor in the motorhome will illuminate each
time InvisiBrake is activated.
Will it brake when I’m driving my car?
No. InvisiBrake only works when your car is being
towed by your motorhome.
What if I think it’s braking
too hard, or not hard enough?
You can easily adjust the braking pressure to a lighter
or heavier setting.
I have an anti-lock braking system
on my car. Will InvisiBrake work with it?
Yes. InvisiBrake will not interfere with your anti-lock
braking system.
My motorhome has an exhaust brake.
Will it cause the InvisiBrake to come on?
Only if the exhaust brake makes your brake lights
turn on. In this event, InvisiBrake protects the towed
vehicle by automatically releasing after 15 seconds of
continuous braking. InvisiBrake will work normally with
your next braking activity.
Why is InvisiBrake a better system?
InvisiBrake is an economical alternative to systems
with proportional braking, such as Even Brake and
BrakeMaster.
InvisiBrake is unique in features such as automatic
connection and disconnection, progressive braking and
automatic battery protection.
It’s made by ROADMASTER, the acknowledged leader
