8.3 SYNCHRONIZING THE BRAKE SYSTEMS
Trailer brakes are designed to work in synchronization with the brakes on the tow vehicle. When
the tow vehicle and trailer braking systems are synchronized, both braking systems contribute to
slowing, and the tongue of the trailer will neither dive nor rise sharply.

If trailer and tow vehicle brakes do not work properly together, death or serious
injury can occur. Road test the brakes in a safe area at no more than 30 m.p.h.
before each tow.
To insure safe brake performance and synchronization, read and follow the axle/brake and the
brake controller manufacturers’ instructions. If you do not have these instructions, contact your
dealer for assistance.
