make small adjustments occasionally to accommo-
date changing loads and driving conditions.
Proper synchronization of the 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,
the trailer brakes should be burnished-in by apply-
ing 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 applica-
tions. This allows the brake shoes and magnets to
slightly “wear-in” to the drum surfaces.
To insure safe brake performance and synchroniza-
tion, read the brake controller manufacturer’s instruc-
tions completely before attempting any synchroniza-
tion procedure.
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 brake controller. If they do not slide, slightly
increase the gain setting. Adjust the brake control-
ler 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
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 brake controller is applying the trailer brakes
before the tow vehicle brakes, then controller adjust-
ments 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 brake 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” to tow vehicle during braking.
Attach and Test the Breakaway System
If the coupler or hitch fails, a properly connected and
working breakaway switch will apply electric brakes
on the trailer. The safety chains will keep the tow
vehicle attached and as the brakes are applied at the
trailer’s axles, the trailer/tow vehicle combination will
come to a controlled stop.
The breakaway system includes a controller, battery,
and a breakaway switch with a pull pin and lanyard.
Read and follow the instructions here as well as the
instructions that have been prepared by the break-
away brake manufacturer. If you do not have these
instructions, call Lance Customer Service at 661-949-
3322 or email service@lancecamper.com for
assistance.
The breakaway system is fitted with a “charging”
capability that draws power from the tow vehicle. If
the electrical system on your tow vehicle does not
provide power to the breakaway brake battery, you
must periodically charge the battery to keep the
breakaway brake system in working order.
• Visually inspect the breakaway system for
broken or missing parts. Repair or replace worn,
damaged or missing parts before towing trailer.
• Connect the pull pin lanyard to the tow vehicle
so that the pull pin will be pulled out before all of
the slack in the safety chains is taken up. Do not
connect the pull pin lanyard to a safety chain
or to the hitch ball or hitch ball assembly. This
would keep the breakaway system from operat-
ing when it is needed.
