Final connections and system test
Test the system

Charge the break away air reservoir — start the mo-
torhome and allow the air compressor to run until it
shuts off. Then, apply the motorhome brakes and hold
the brake pedal down.
The break away air reservoir must be charged,
as described above, every time the motorhome and
towed vehicle are connected. If the air reservoir is
not charged, the break away system will not ap-
ply braking pressure if the towed vehicle separates
from the motorhome, which may cause property
damage, personal injury or even death.
Next, remove the break away pin at the front of the
break away switch. The air cylinder and pedal clamp
will extend, confirming the proper operation of the break
away system.
To retract the air cylinder and pedal clamp, briefly
disconnect the quick couplers from the air line extending
from the air cylinder. Then, reconnect the break away
pin.
Before towing, charge the break away air reservoir,
as described above.
6. Confirm the proper operation of the towed vehicle’s
brake lights and turn signals —
A. Depress the motorhome brake pedal; confirm
that the towed vehicle’s brake lights illuminate. Activate
both of the motorhome turn signals; confirm that the
towed vehicle’s turn signals activate.
If the towed vehicle’s brake lights and turn signals
do not operate in tandem with the motorhome’s, you
must install a non-intrusive lighting system or re-wire
the towed vehicle. See “Brake light solutions” in the
complete BrakeMaster installation instructions.

www.roadmasterinc.com. Select ‘Installation Instruc-
tions' under ‘Support.')
B. With one of the motorhome turn signals acti-
vated, depress the motorhome brake pedal. Confirm
that the towed vehicle’s brake lights and turn signal
both illuminate.
If the towed vehicle’s brake lights override the turn
signal, you must install a non-intrusive lighting system
or re-wire the towed vehicle. See “Brake light solutions”
in the complete BrakeMaster installation instructions.
By law, a towed vehicle’s turn signals and brake
lights must operate in tandem with the motorhome’s,
as described above. If they do not, drivers behind
the towed vehicle will not be alerted when the mo-
torhome stops or turns, which may cause an ac-
cident.
If the towed vehicle’s brake lights and turn sig-
nals do not operate in tandem with the motorhome’s,
either install a non-intrusive lighting system or re-
wire the towed vehicle according to “Brake light
solutions” in the complete BrakeMaster installa-
tion instructions. Then, test for proper operation,
as described in step 6, above.
