Synchronizing Your Trailer Brakes
To insure safe brake performance and synchronization,
read the
brake controller manufacturer's instructions completely before
attempting any synchronization procedure.
!
CAUTION
Before road testing, make sure the area is clear of
vehicular and pedestrian traffic. Failure to brake safely
could result in an accident and personal injury to
yourself and/or others.
Make several hard stops from 20 m.p.h. on a dry paved road free
of sand and gravel. If the trailer brakes lock and slide, decrease
the gain setting on the controller. If they do not slide, slightly
increase the gain setting. Adjust the controller just to the point of
impending brake lockup and wheel skid.
Note: Not all trailer brakes are capable of wheel
lockup. Loading conditions, brake type, wheel and tire
size can all affect whether a brake can lock. It is not
generally considered desirable to lock up the brakes
and slide the tires. This can cause unwanted flat
spotting of the tires and could also result in a loss of
control.
If the controller is applying the trailer brakes before the tow
vehicle brakes, then the controller adjustments should be made
so the trailer brakes come on in synchronization with the tow
vehicle brakes. For proper braking performance, it is
recommended that the controller be adjusted to allow the trailer
brakes to come on just slightly ahead of the tow vehicle brakes.
When proper synchronization is achieved there will be no
sensation of the trailer “jerking” or “pushing” the tow vehicle
during braking.
