FORD 2015 F-550 v.1 - Manual (Page 201)

Trailer Brakes
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.
Electric brakes and manual,
automatic or surge-type trailer
brakes are safe if you install them
properly and adjust them to the
manufacturer's specifications. The
trailer brakes must meet local and
federal regulations.
The rating for the tow vehicle's
braking system operation is at
the gross vehicle weight rating,
not the gross combined weight
rating.
Separate functioning brake
systems are required for safe
control of towed vehicles and
trailers weighing more than
1500 pounds (680 kilograms)
when loaded.

Controller
(If Equipped)
WARNING
The Ford trailer brake
controller has been verified
to be compatible with trailers
having electric-actuated drum
brakes (one to four axles) and
some electric-over-hydraulic
brakes. It will not activate
hydraulic surge-style trailer
brakes. 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.

When used properly, the trailer
brake controller assists in smooth
and effective trailer braking by
powering the trailer’s electric or
electric-over-hydraulic brakes
with a proportional output based
on the towing vehicle’s brake
pressure.
