Coupling To The Tow Vehicle
Bri-Mar 66
Figure 4-7 – Breakaway Brake Connection
• Connect the pullpin lanyard to the tow vehicle so that the pullpin will
be pulled out before all of the slack in the safety chains is taken up.
See figure 4-7. Do not connect the pullpin cable to a safety chain or
to the hitch ball or hitch ball assembly. This would keep the
breakaway brake system from operating when it is needed.
• To test the breakaway brake battery remove the pullpin from the
switch and attempt to pull the trailer forward. You should feel the
trailer resisting being towed, but the wheels will not necessarily be
locked. If the brakes do not function, do not tow the trailer until
brakes, or battery, are repaired.
• Immediately replace the pullpin. The breakaway brake system
battery discharges rapidly when the pullpin is removed.
^ WARNING
An ineffective breakaway brake system can result in a runaway trailer,
leading to death or serious injury, if the coupler or ball hitch fails.
Connect the breakaway cable to the tow vehicle; and NOT to the hitch,
ball or support.
Before towing the trailer, test the function of the breakaway brake
system. If the breakaway brake system is not working, do not tow the
trailer. Have it serviced or repaired.
Do not tow the trailer with the breakaway brake system ON because the
brakes will overheat which can result in permanent brake failure.
