Normal Operation
This braking system is designed to brake your towed car whenever it senses deceleration from your RV. Under
normal circumstances, the unit will activate whenever your RV is decelerating faster than your towed car (that is,
you are stopping your RV). If you are riding your foot on the brakes of the RV, then the braking system will not
activate because the RV is not slowing more quickly than the car. Similarly, when you come to a full stop, the
system will release since there is no longer any deceleration. The system will activate whenever it senses decelera-
tion in the RV. The unit consumes battery power in your towed car as you drive. Roadmaster recommends that you
start your towed vehicle after towing for more than 6 hours and let it idle 15 to 20 minutes to re-charge your battery.
To make sure your battery is re-charged, make sure your low battery light on the towed vehicle is not lit.
IMPORTANT! Battery conditions such as age or capacity will affect usage, time, and time to recharge.
How to remove the braking system
1. Unplug 12 volt power cord.
2. Unplug monitor and BrakeAway wires.
3. Press air relief.
4. Slide seat to rearmost position.
5. Detach clamp from brake pedal by pushing on the lower edge
of the release tab or pulling the top of the release tab towards
you which is located on the left of the clamp as seen in
figure 4, and lift the unit out of vehicle.
6. Wrap 12 volt cord onto cord holder.
7. Transmitter and Receiver can be left in place or stored.
8. Be sure BrakeAway cord is safely secured so that it cannot become entangled while driving vehicle.
9. It is okay to remove Breakaway cable; however, do not remove the Breakaway pin as:
a.) Dirt will accumulate in Break Away switch possibly causing unwanted activation or preventing proper
operation of Break Away.
b.) Failure to reinsert pin before installing the braking system unit will cause unwanted activation, potentially
causing injury or property damage.
CAUTION:
!
Do not tow with your towed vehicle’s engine running. This will energize the power brake
system and cause severe braking, resulting in non-warranty brake damage.
CAUTION:
!
Never leave Breakaway pin out of Break Away switch. Failure to reinsert pin
before installing the unit will cause unwanted activation, potentially causing
injury or property damage.
