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.
If electric breakaway brakes do not operate when trailer is uncoupled
from the tow vehicle, death or serious injury can occur.
Check emergency breakaway brake system BEFORE each tow.
8.2.3.4 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. If you do not have an axle and brake manual,
call Bri-Mar Manufacturing LLC at 1-717-263-6116 for a free copy.
8.2.3.5 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 brake manual for wear and current
inspection instructions.
