TRAILER BRAKES
In some states, any trailer with a GVWR of 1500 lb (680 kg) or more is required to
have trailer brakes. Check with your state and local authorities for more
information.
The three basic types of trailer brakes are electric, hydraulic surge and
air-actuated. If your trailer is equipped with brakes, see the
Trailer Operator’s
Manual for more information on operation, adjustments and maintenance.

5-Pin Wiring Connector
Some trailers equipped with surge brakes may utilize a 5-pin wiring connector.
These trailers use an electric solenoid valve that allows brake fluid to bypass back
to the reservoir while in REVERSE. The solenoid is usually connected to the
reverse lights on the tow vehicle to ensure the brakes only bypass in REVERSE.
The fifth pin is for deactivating the brakes when backing up, and is required to be
connected to the vehicle’s power when backing up. In some instances, the 5-pin
connector can be connected to a 4-pin connector for normal operation of the
lights.
