Roadmaster AddaBRAKE 8800 - Test Braking System

functions properly.
Failure to follow these instructions may cause
property damage, personal injury or even death.
4. Confirmtheproperoperationoftheextendedbraking
mode:depressandholdthemotorhome’sbrakepedal
down. The AddaBRAKE air cylinder shaft and pedal
clampwillextend.Afterapproximately15seconds,the
aircylindershaftandpedalclampwillretract.
5. Confirmtheproperoperationoftheaudioalert:de-
pressandholdthetowedvehicle’sbrakepedaldown.
Afterapproximately20seconds,themotorhomemonitor
willactivatetheaudioalert.(Tocanceltheaudioalert,
releasethetowedvehicle’sbrakepedal.)
6. Confirmthatthemotorhometurnsignalsdonotac-
tivateAddaBRAKE.
An incorrect flasher speed may activate Adda-
BRAKE unnecessarily, causing excessive brake
wear or other consequential, non-warranty dam-
age.
If the turn signals activate AddaBRAKE, check
the turn signal flasher rating — it may be inadequate
for the motorhome-towed vehicle combination. If
this is the case, replace the flasher with one rated
at or above the number of bulbs in the motorhome-
towed vehicle combination.
Test the braking system
continued from preceding page
pare the vehicle for towing. These adjustments may
include: turning the ignition key to the “tow” position;
pulling fuses; disconnecting the battery; and setting
the transmission to a particular gear or in a particular
sequence.
Refer to the owner’s manual, or call the dealership
or the manufacturer for vehicle-specific information.
1. ConnectAddaBRAKEaccordingtotheinstructions
inthenextsectioninthismanual—“Day-to-dayopera-
tion.”
2. Confirmtheproperoperationofthesupplemental
braking system: depress and hold the motorhome’s
brakepedaldown.TheAddaBRAKEaircylindershaft
and pedal clamp will extend (after approximately two
seconds).Then,releasethebrakepedal.Atthetowed
vehicle, the AddaBRAKE air cylinder shaft and pedal
clampwillretract.
If the vehicle will be (or has been) wired for tow-
ing (as opposed to installing a taillight wiring kit or
magnetic tow lights), diodes must be attached in
order for AddaBRAKE to release the towed vehicle’s
brakes in tandem with the motorhome. If diodes are
not attached, AddaBRAKE will apply braking pres-
sure for approximately 15 seconds each time the
motorhome brakes are applied, regardless of when
the motorhome brakes are released.
Damage to the towed vehicle’s braking system,
as well as other consequential damage, may oc-
cur.
Refer to step 10 under “Before you begin the
initial installation” for additional information.
3. Confirmthatthemotorhomemonitorisfunctioning:
theLEDwillilluminateafterthemotorhome’sbrakeped-
alisdepressed(afterapproximatelytwoseconds),and
stopilluminatingwhenthebrakepedalisreleased.
If the LED does not illuminate…
…it may indicate that AddaBRAKE is wired incor-
rectly. If AddaBRAKE is wired incorrectly, it will not
brake the towed vehicle in tandem with the motor-
home. Insufficient braking pressure will lengthen
stopping distance, and may also cause a loss of
vehicular control.
Refer to the ‘Troubleshooting’ section (under
‘Electrical’) for possible causes. If AddaBRAKE
has been incorrectly wired, identify and correct
the mistake, then test to ensure that AddaBRAKE
