Breakaway Switch Mounted on an A-
Frame
Attach breakaway switch cable securely in a straight
line to the tow vehicle. Locate attachments so little
"slack" is left in the cable, but enough slack to allow for
turning without disengaging the pin. The cable will
activate brakes the instant a trailer becomes disen-
gaged. Brake adjustment is critical to stopping a disen-
gaged trailer.

What to Check and How to Check

Brakes

Your trailer is equipped with electric brakes.
Complete service and repair information for the electric
brakes is found in the Axle Break Service Manual that
is furnished with your trailer,
Note: It is important to strictly adhere to the axle break
instructions for brake service and repair. In this way,
you are protecting the validity of all applicable warran-
ties.

Burnishing the Brakes

Brakes on a new trailer may tend to "grab" or pulsate.
This is normal. To correct the situation, pull the trailer
with the trailer brake control slightly engaged a short
distance (about 1000 ft or until trailer does not grab or
pull to one side anymore). This action smooths down
the brake bands.
NOTE: Do not lock up the wheels
