BREAKAWAY BRAKE
This battery supplies the power to operate the trailer brakes if the trailer uncouples from
the tow vehicle. Be sure to check, maintain and replace the battery according to the
battery manufacturer’ instructions.
BREAKAWAY SWITCH
This switch causes the breakaway battery to operate the electric brakes if the trailer
uncouples from the tow vehicle.
The pull cable for the pull pin is connected to the tow vehicle, and the switch is
connected to the trailer. To check for proper functioning of the switch, battery and
brakes, you must pull the pin from the switch and confirm that the brakes apply to each
wheel. You can do this by trying to pull the trailer with the tow vehicle, after pulling the
pin. The trailer brakes may not lock, but you will notice that a greater force is needed to
pull the trailer.
Warning: If electric breakaway brakes do not operate when trailer in uncoupled from the
tow vehicle, death or serious injury can occur. Check emergency breakaway brake
system BEFORE each tow.
TOW VEHICLE OPERATED ELECTRIC BRAKES
The electric brakes that operate in conjunction with the tow vehicle brakes must be
“synchronized” so that braking is properly distributed to the tow vehicle brakes and the
trailer brakes. For proper operation and synchronization, read and follow the axle/brake
and the brake controller manufacturers’ instructions.
MAGNETS FOR ALL ELECTRIC BRAKES
To make certain an electrically operated braking system will function properly, you must
have your dealer inspect the magnets at least once a year, or each 12,000 miles. See the
axle manual for wear and current inspection instructions.
D. TRAILER COMPONENTS
COUPLER & BALL
The coupler on the trailer connects to the ball attached to the hitch on the tow vehicle.
