Questions
What is BrakeMaster?
BrakeMaster connects directly to the motorhome’s air
or hydraulic brake system, so that brake line pressure
in the motorhome controls the brakes in the towed ve-
hicle. Because it connects directly to what powers your
motorhome’s brakes, BrakeMaster is a truly synchro-
nized, proportional braking system.
Whatdoes‘proportionalbraking’mean?
Proportional braking is even braking — your towed
vehicle’s brakes respond to your motorhome’s brakes,
at the same time and at the same intensity.
HowdoesBrakeMasterwork?
BrakeMaster uses air pressure to proportionately acti-
vate an air cylinder that applies the brakes in the towed
vehicle just as if you were pressing on them yourself.
WheredoesBrakeMastergetitsairsupply?
If your motorhome has air brakes, BrakeMaster is
connected to the existing braking system. If your mo-
torhome has hydraulic brakes, there’s a BrakeMaster
system that includes a compressor to supply air to the
BrakeMaster air cylinder.
Myvehiclehaspowerbrakes,butwhenthe
engine is turned off, the power brakes do not
function.WillBrakeMasterworkonmyvehicle?
Yes. BrakeMaster is designed to work with vehicles
that have a power brake system, but the engine (and
the power brakes) are turned off while the vehicle is
being towed.
Isthemotorhome’sbrakeline,orthe
brakelinepressure,compromisedinanyway?
No. Typically, one pre-existing fitting is removed, and
replaced with another. This replacement fitting (as well
as all hardware used to install BrakeMaster) meets or
exceeds the automotive manufacturing standards es-
tablished by both the Department of Transportation
and the American National Standards Institute.
Willitworkinmymotorhome
andtowedvehicle?
Yes. The BrakeMaster air cylinder is universal, and
works in virtually any towed vehicle with power brakes.
The type of braking system in your motorhome deter-
mines which BrakeMaster is right for you — kits are
available for motorhomes with air brakes, air over hy-
draulic brakes, or hydraulic brakes.
CanIswitchitbetweentowedvehicles?
Yes. Second vehicle kits are available. These allow you
to have a braking system for both (or more) towed ve-
hicles without the expense of another complete system.
Doesitfitinmycar?
BrakeMaster fits in virtually all vehicles.
Howlongdoesittaketoinstall?
Depending on the type of brakes in your motorhome,
the initial installation takes from six to eight hours. Af-
ter the initial installation, it only takes a minute or two
to connect or disconnect from the towed vehicle.
CanIinstallitmyself?
We recommend that you have BrakeMaster installed
by a competent mechanic, with experience in motor-
home installations.
HowdoIknowit’sworking?
A monitor light in the motorhome dash illuminates
when the towed vehicle’s brakes are applied.
Ihaveananti-lockbrakingsystemon
mycar.WillBrakeMasterinterferewithit?
No. Anti-lock braking only works when the car’s pow-
er is on. Since the power will be turned off when you
tow your vehicle, BrakeMaster will not interfere with
your anti-lock braking system.
WhyisBrakeMasterbetter?
• Rock-solid, reliable braking — because it connects
directly to what powers your motorhome’s brakes,
BrakeMaster is a truly proportional, truly synchronized
braking system — however you brake the motorhome,
BrakeMaster automatically applies the same pressure.
Every time.
• Very easy to use — once the system is installed,
BrakeMaster connects and disconnects from the towed
vehicle in under a minute, without any tools, adjust-
ments or settings.
• Weighs just 3¾ pounds and measures 17 inches in
length — stores almost anywhere.
• The towed vehicle’s brakes are not altered in any
way, so the factory warranty is not affected.
• 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.
