Roadmaster AddaBRAKE 8800 - Troubleshooting; Positioning Issues; Brake Pressure Setting Issues

TROUBLESHOOTING
Symptom
AddaBRAKE doesn’t fit properly
inthetowedvehicle.
 The pedal clamp doesn’t fit the
brakepedalsecurely.
 Theaircylindershaftwillnotex-
tendtoconnectthepedalclampto
thebrakepedal.
 Thepedalclampdoesnotextend
to the brake pedal, when Adda-
BRAKEisproperlyinstalled.
 The brake pedal clamp comes
into contact with the AddaBRAKE
housing.
 Thetowedvehicle’sseatmoves
after AddaBRAKE depresses the
brakepedal.
AddaBRAKE “climbs” up the
seat.
 After towing, there is excessive
brake dust on the wheels of the
towed vehicle, and/or an unusu-
al odor near the towed vehicle’s
brakes.
Question
 How do I increase or decrease
brakingpower?
Symptom
 ThefirsttimeAddaBRAKEisac-
tivated, the towed vehicle brakes
with excessive force, ‘flat-spotting’
thetires.
Solution
Positioning
 UseoneormorefootextensionstoelevateAddaBRAKEoverobstruc-
tionssuchasductwork,adoorjamboracenterconsolethatjutsintothe
availablespace.(Refertothe“OptionalEquipment”section.)
 Useapairofplierstobendthetabsofthepedalclampforabetterfit.
Ifthepedalclampstilldoesn’tfit,contactROADMASTER.
 Theairreservoirisfull.Releasetheairbypressingtheairreliefbutton
(Figure5).
 Usean optionalair cylinder shaftextension toextendthe reachofthe
aircylindershaft.(Refertothe“OptionalEquipment”section.)
 Brake pedals that are somewhat horizontal cause the pedal clamp to
tilt,andtointerferewiththeAddaBRAKEhousingwhenitretracts.Usean
optionalaircylindershaftextensiontogainadditionalclearance.(Referto
the“OptionalEquipment”section.)
 Readjust the seat and/or the adjustable seat pad. Refer to Step B in
“Day-to-dayoperation”—“Adjustthefeetandtheseatpad.”
 Afteradjustingtheseat,pressthe“Test”button(Figure12)down,then
release it, to cycle the pedal clamp up and down threetimes.Watch the
seatastheaircylindershaftextendsandretracts—ifitstillmoves,adjust
theseatasecondtime,andrepeatthetestcycle.
• If there is a rubberized floor mat under AddaBRAKE, remove it during
towing.
• Checkthepositionoftheadjustableseatpad.Theseatpadservesas
ananchorpoint,tokeepAddaBRAKEdownasitpressesthebrakepedal.
Adjusttheseatpadupordown,ifnecessary.
Brake pressure setting
 Readjust the braking pressure to a lower setting. Refer to Step E in
“Day-to-dayoperation”—“Setthebrakepressure.”
Answer
 Readjustthebrakingpressuretoahigherorlowersetting.RefertoStep
Ein“Day-to-dayoperation”—“Setthebrakepressure.”
Solution
Installed in vehicle with ‘active’ brakes
