Technical information

WhatisInvisiBrake?
InvisiBrake is a fully-automatic, progressive supple-
mental 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 ac-
tivates 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 compo-
nents 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 ini-
tial installation, InvisiBrake is always ready to tow, with
no adjustments necessary.
FrequentlyAsked
Questions
InvisiBrake
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 lead-
er in RV towing products. More people put their trust
in ROADMASTER towing systems than in any other
brand.
