Figure 54. Safety Chain Arrangement for a Bumper Pull Trailer (Ball Hitch)

Breakaway Brake System

If the coupler or hitch fails, a properly connected and work- ing breakaway brake system (Figure 55) will apply the hy- draulic brakes on the trailer. The safety chains will keep the tow vehicle attached and as the brakes are applied at the trailer’s axles, the trailer/tow vehicle combination will come to a controlled stop.

Breakaway Lever

 

Tow Vehicle

 

Hydraulic Actuator

Visually inspect the safety chains and hooks for wear or damage. Replace worn or damaged safety chains and hooks before towing.

Attach the safety chains so that they:

A.Cross underneath the coupler. See Figure 54.

B.Loop around a frame member of the tow vehicle or holes provided in the hitch system (DO NOT attach them to an interchangeable part of the hitch assembly).

C.Have enough slack to permit tight turns, but not be close to the road surface, so if the trailer un couples, the safety chains can hold the tongue up above the road.

WARNING - Safety Chains Rigging

Improper rigging of the safety chains can result in loss of control of the trailer and tow vehicle, leading to death or serious injury, if the trailer uncouples from the tow vehicle.

Fasten chains to frame of tow vehicle. DO NOT fasten chains to any part of the hitch unless the hitch has holes or loops specifically for that purpose.

Cross chains underneath hitch and coupler with enough slack to permit turning and to hold tongue up, if the trailer comes loose.

Figure 55. Breakaway Brake System

Breakaway Cable Surge Brake System

The breakaway brake system includes a brake cable con- nected to the tow vehicle on one end and to the emergency brake lever located on the hydraulic actuator on the other end.

WARNING - Brakeaway Cable

An ineffective breakaway brake system can result in a runaway trailer, leading to death or serious injury, if the coupler or ball hitch fails.

Connect the breakaway cable to the tow vehicle; and NOT to the hitch, ball or support.

Before towing the trailer, test the function of the breakaway brake system. If the breakaway brake system is not working, DO NOT tow the trailer. Have it serviced or repaired.

DO NOT tow the trailer with the breakaway brake system ON because the brakes will overheat which can result in permanent brake failure.

Replace the breakaway brake battery (if equipped) at intervals specified by manu- facturer.
