How to Use Your Electric Brakes Properly
Your trailer brakes are designed to work in synchronization with
your tow vehicle brakes. Never use your tow vehicle or trailer
brakes alone to stop the combined load.
Your brake controller must be set up according to the
manufacturer's recommendations to ensure proper
synchronization between the tow vehicle and the trailer.
Additionally, you may have to make small adjustments
occasionally to accommodate changing loads and driving
conditions.
Proper synchronization of tow vehicle to trailer braking can only
be accomplished by road testing. Brake lockup, grabbiness, or
harshness is quite often due to the lack of synchronization
between the tow vehicle and the trailer being towed, too high of a
threshold voltage (over 2 volts), or under adjusted brakes.
Before any synchronization adjustments are made, your trailer
brakes should be burnished-in by applying the brakes 20-30
times with approximately a 20 m.p.h. decrease in speed, e.g. 40
m.p.h. to 20 m.p.h. Allow ample time for brakes to cool between
application. This allows the brake shoes and magnets to slightly
"wear-in" to the drum surfaces.
