Understanding Trailer Towing Systems

The all-new 2011 F-Series Super Duty Pickups and Chassis Cabs are all about capability – capability to get the job done with confidence. It is no small wonder that the majority of Super Duty owners use their trucks for towing, especially when you consider these impressive Super Duty bragging rights:

  • Best-in-class maximum conventional towing – 16,000 lbs. (Pickups and Chassis Cabs)
  • Best-in-class maximum 5th-wheel towing capacity – 24,400 lbs. (Pickups), 26,400 lbs. (Chassis Cabs)
  • Best-in-class maximum Gross Vehicle Weight Rating (GVWR) – 13,050 lbs. (Pickups)
  • Best-in-class maximum Gross Combination Weight Rating (GCWR) – 33,000 lbs. (Pickups), 35,000 lbs. (Chassis Cabs)

The two key components of Super Duty’s towing capabilities are standard Trailer Sway Control and available factory-installed, fully integrated Trailer Brake Controller (TBC).

TRAILER SWAY CONTROL

Trailer Sway Control and AdvanceTrac with RSC (Roll Stability Control) are standard on all Super Duty Pickup and single-rear-wheel (SRW) Super Duty Chassis Cab models. Trailer Sway Control is provided as a function of a module within the AdvanceTrac software that monitors the motions of the truck to detect sway while towing. When motion is detected, the system works to apply selected brakes and/or reduce engine power to help the driver regain control.

Dual-Rear-Wheel Trailer Sway Control

Dual-rear-wheel pickups, while not equipped with AdvanceTrac, provide Trailer Sway Control function in the following way:

  • A yaw motion sensor, very similar to that used in single-rear-wheel models, is incorporated into the braking system of dual-rear-wheel models.
  • This sensor monitors for trailer sway
  • When trailer sway is detected, the system responds by applying brake pressure selectively to the front brakes or reduces engine power to help the driver regain control

TRAILER BRAKE CONTROLLER

The available Super Duty Trailer Brake Controller (TBC) is factory-installed and fully integrated into the instrument panel and the truck’s onboard computer. The TBC ensures smooth and effective trailer braking by powering the trailer’s electric brakes with an output proportional to the towing vehicle’s electric brakes with an output proportional to the towing vehicle’s brake pressure.

TBC Compatibility

The Ford TBC has verified compatibility with trailers (one to four axles) utilizing electrically actuated drum brakes and certain Electric-Over-Hydraulic (EOH) actuated drum or disc brake systems. A trailer that features a surge brake system can be used with Super Duty; however, trailer surge brakes are not integrated into the TBC.

ELECTRIC-OVER-HYDRAULIC (EOH) TRAILER BRAKE FACTS

 

What Are EOH Brakes?

  • Electric-Over-Hydraulic trailer brakes, more commonly known as EOH, differ from the more common electric trailer brakes
  • EOH brakes are operated by an electrically powered pump that pressurizes a hydraulic fluid reservoir built into the trailer’s brake system
  • The fluid reservoir pressurizes either a wheel cylinder (drum brakes) or a caliper (disc brakes) in much the same way a vehicle master cylinder applies pressure to the braking system
  • EOH trailer brakes offer certain benefits over electric trailer brakes, such as:

                Smoother operation

                More responsive/predictable braking

                 Better adaptability in wet environments (such as boat trailers) than conventional electric trailer brakes

  • The factory-installed TBC is already compatible with certain EOH systems in the trailer marketplace
