Trailer brakes

Electric brakes and manual, automatic or surge-type trailer brakes are

safe if installed properly and adjusted to the manufacturer’s

specifications. The trailer brakes must meet local and Federal

regulations.

WARNING: Do not connect a trailer’s hydraulic brake system

directly to your vehicle’s brake system. Your vehicle may not

have enough braking power and your chances of having a collision

greatly increase.

The braking system of the tow vehicle is rated for operation at the

GVWR not GCWR.

Integrated trailer brake controller (if equipped)

Your vehicle may be equipped with a fully integrated electronic trailer

brake controller (TBC). When used properly, the TBC helps ensure

smooth and effective trailer braking by powering the trailer’s electric

brakes with a proportional output based on the towing vehicle’s brake

pressure.

WARNING: The Ford TBC has only been verified to be

compatible with trailers having electric-actuated drum brakes

(one to four axles) and not hydraulic surge or electric-over-hydraulic

types. It is the responsibility of the customer to ensure that the trailer

brakes are adjusted appropriately, functioning normally and all electric

connections are properly made. Failure to do so may result in loss of

vehicle control, crash or serious injury.

The TBC user interface consists of

the following:

1. +/- (GAIN adjustment

buttons): Pressing these buttons

adjusts the TBC’s power output to

the trailer brakes (in

0.5 increments). The GAIN setting

can be increased to a maximum of

10.0 or decreased to a minimum of 0 (no trailer braking). Pressing and

holding a button raises or lowers the setting continuously. The gain

setting displays in the message center as follows: TBC GAIN = XX.X.
