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 the 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.
