Roadmaster AddaBRAKE 8800 - Quick Reference Checklist; Connecting AddaBRAKE

QUICK REFERENCE CHECKLIST
If the vacuum is not released, AddaBRAKE will
apply excessive braking force when it is activated,
which will cause severe tire and/or brake system
damage to the towed vehicle.
9. Connect the AddaBRAKE wiring harness to the
breakawaywiringharnessandthebrakesignalwire.
10. Connectthe break awaycableto thefrontofthe
towedvehicleandtotherearofthemotorhome.Peri-
odically,testthebreakawaysystem.
11. Connectthemonitorpatchcordtothefrontofthe
vehicleandtotherearofthemotorhome.
Note: this step is unnecessary if the monitor wiring
was connected to the electrical sockets in the towed
vehicle and the motorhome. Refer to Steps C and F
under “Initial Installation.”
12. Testto confirm theproper operationofthepedal
clamp,themotorhomemonitorLED,andtheextended
brakingprotectionmode.(Periodically,confirmtheprop-
eroperationofthemonitoraudioalert,andthatthemo-
torhometurnsignalsdonotactivateAddaBRAKE.)
13. Makecertainthatthetowedvehicle’s emergency
brakeisreleased.
Failure to release the towed vehicle’s emergency
brake before towing will result in severe tire and
brake damage, or a brake system fire, or other con-
sequential damage. Damage caused by towing a
vehicle with its emergency brake on is not covered
under warranty.
Failure to follow these instructions may cause
property damage, personal injury or even death.
AddaBRAKE is designed to work with a ‘dead’
brake pedal. Do not leave the vehicle’s engine
running while towing, as this will allow the power
brakes to function. The power brakes will cause
excessive braking in the towed vehicle, resulting in
non-warranty brake system and tire damage. Dis-
connect AddaBRAKE if, for any reason, you must
tow with the engine running.
If the towed vehicle’s engine must be started pe-
riodically (according to the manufacturer’s instruc-
continued on next page
O
nce the other components of your supplementary braking system have been installed, follow the steps
belowtoconnectAddaBRAKEtothetowedvehicle;seethenextpagetodisconnectAddaBRAKE.Formore
detailedinformation,refertotheappropriatesectionunder“Day-to-dayoperation.”
Connecting AddaBRAKE
1. Slidethedriver’sseatback,asfarasitwillgo.
2. PositionAddaBRAKEbetweenthedriver’sseatand
thebrakepedal, attheapproximate position itwillsit
whenconnectedtothebrakepedal.
3. Presstheairreliefbutton(Figure5)tomakecertain
thatalloftheairintheAddaBRAKE airreservoirhas
beenreleased.
4. Attachthepedalclamptothebrakepedal.
5. Move AddaBRAKE forward, until the air cylinder
shaft(Figure9)isfullyretracted.
6. Slidethedriver’sseatforward,untilitjusttouches
theAddaBRAKEadjustableseatpad.Ifnecessary,al-
lowa smallgap,rather than allowing AddaBRAKE to
depressthebrakepedal.
The driver’s seat must not be too far forward,
to the extent that the AddaBRAKE pedal clamp is
depressing the towed vehicle’s brake pedal.
If the brake pedal is depressed, the brakes will
be applied continuously, which will cause severe
tire and/or brake system damage, as well as other
consequential, non-warranty damage.
Failure to follow these instructions may cause
property damage, personal injury or even death.
7. Plug in the 12-volt power cord, and secure it by
pressingthecordlock(Figure11)intothe12-voltout-
let.
  Whenthepowercordispluggedin,theaircompres-
sorwillrununtiltheairreservoirisfilled.
8. Oncetheairreservoirisfilled,pressandrelease
the“Test”button(Figure12).Thepedalclampwillcycle
upanddownthreetimes.
  IfAddaBRAKEmovesexcessively,orinterfereswith
seat position controls, adjust its position. Check the
adjustableseatpadandreadjustit,ifnecessary.
Always deplete the stored vacuum in the towed
vehicle’s power brake system before towing — press
the “Test” button down, then release it, to cycle the
pedal clamp up and down three times.
Depending on the make and model of the towed
vehicle, it may be necessary to repeat the test cycle
a second time.
