Adjustment and Operation of Brakes

WARNING:

Do not operate this vehicle with any brake defects or with brakes out of

adjustment.

CHECK BRAKE OPERATION

Before entering traffic, check the operation of the trailer brakes to be sure

they are in good working order. Try foot pedal, emergency dash control

valve (push, pull or flip), and trailer brake lines to assure brake application

and release in each instance. Listen for air leaks under each condition.
