As stated above, the best way to operate the solenoid is with a
5-prong wire harness on the tow vehicle that matches the wire har-
ness plug of the trailer. This allows the solenoid to be plugged in
at the same time the trailer lights are connected for towing. If a
5-prong harness is not available there are a number of short-term
fixes that will allow you to use the trailer.
UFP ACTUATOR LOCKOUT KEY
UFP actuators are shipped with a lockout key attached to the side
of the actuator on a short cable. The round end of the key is simply
inserted in the slot on the side of the actuator. When the key is in
the slot, the trailer can be backed without the brakes engaging.
When the trailer is moved forward, the key will fall out of the slot.
The key fits very loosely to insure that it will not remain in the slot
after backing. Leaving the lockout key in the slot would disable the
brake system during normal use, which could result in a serious
accident.
ADDING A 5TH WIRE & PLUG
A separate wire and plug can be wired into the tow vehicle back-up
lights that can be plugged into the fifth wire of the trailer harness.
The solenoid will work as described above, however this new wire
will have to be plugged into the trailer harness separately.
USING A 4-PRONG PLUG
If the tow vehicle is equipped with a 4-prong plug, the trailer can
still be moved using the solenoid to lock out the brakes. Though not
ideal, this is acceptable for backing trailers in either a storage yard
or a shop environment where the tow vehicle is not the normal ve-
hicle that will be used with the trailer. Before backing, simply unplug
the trailer’s 5-prong harness from the tow vehicles 4-prong trunk
harness. Turn the harness 90 degrees and plug the blue wire on
the 5-prong harness into the brown wire on the 4-prong harness. To
activate the solenoid, turn on the tow vehicle’s lights. The power for
operating the running lights will operate the solenoid, disengaging
the brakes so the trailer can be backed up.

BRAKE SERVICE AND MAINTENANCE
WARNING: Trailer brakes must be maintained in good working
conditions. Loss of adequate braking could result in serious in-
jury or property damage.
The braking systems are covered in much greater detail in the
Brake Information Packet that pertains to brake systems and
brake components only. Contact your local dealer or contact
Shoreland’r
®
directly to receive a copy of this information.
This trailer is equipped to meet applicable U.S. Federal safe-
ty standards. Check local and state requirements regarding
brakes and any additional equipment that may be required.
Any modifications or additions including load equalizing
hitches, without written factory consent: usage in an abnor-
mal manner including overloading voids all manufacturers
warranties and liability.
REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect which could cause
a crash or could cause injury or death, you should immediately
inform the National Traffic Safety Administration (NHTSA) in ad-
dition to notifying us.
slot in the nut, turn the nut counterclockwise until the next slot in the
nut lines up with the cross hole. Insert the cotter key.
If you cannot see any potion of the hole in the spindle through the
slots in the nut, turn the nut counterclockwise until the hole lines up
with the first slot available in the nut. Insert the cotter key.
This adjustment will give you from one-thousandths to ten-thou-
sandths end play which is in tolerance for proper adjustment. Check
wheel again for movement. If no movement, spin wheel. Check the
wheel again for movement. If no movement, spin the wheel again.
The wheel should turn easily and have no end play (lateral move-
ment). Re-insert the cotter key, then bend the ends to keep it from
coming out. Place the dust cover or bearing protector into position.
Tap lightly on the edges to start the cover into the hub. Then using
a screwdriver on alternating sides as you work around the dust
cover, tap the screwdriver with a hammer until the dust cover is
completely into the hub and the flange on the dust cover is it tight
against the hub face. If you are installing a bearing protector, once
it is started into the hub place a wood board over the bearing pro-
tector and then tap evenly and lightly until the flange is completely
against the face of the hub.
Repeat the above process on the other wheels.
BRAKE SERVICE & MAINTENANCE OF
BRAKING SYSTEMS
ShoreLand’r
®
uses only a hydraulic surge brake system with a
hydraulic surge actuator on their utility trailers. This system has an
actuator on the tongue of the trailer that attaches to the tow vehicle.
It is designed that when the brakes are applied on the tow vehicle
the trailer will push into the tow vehicle. As this load is applied to the
actuator a master cylinder inside the actuator generates pressure
on the brake fluid that is then supplied to the wheel cylinders of
the drum brakes or into the calipers on disc brake systems. As this
brake fluid is supplied the pressure is applied to the brake shoes or
pads causing the brakes to apply on the trailer.
BACKING UP A TRAILER WITH DISC BRAKES
OPERATING TRAILERS WITH DISC BRAKES
Many ShoreLand’r
®
trailers come with disc brakes as standard
equipment. This system is designed to brake in both forward and
reverse, therefore the brakes must be disengaged to back up.
IMPORTANT: To properly operate this system the tow vehicle
MUST be equipped with a matching 5-prong trunk harness to
power the solenoid. Otherwise, a lockout key must be used (this
key is provided with your actuator).
TRAILER’S 5-PRONG WIRE HARNESS REQUIREMENTS
Required 5-prong trunk harness on tow vehicle.
HOW THE SOLENOID LOCKOUT WORKS
The disc brake actuator has a lockout solenoid that is activated by
the tow vehicle’s back-up lights. When the vehicle is put in reverse,
the solenoid redirects the brake fluid back into the actuator reservoir
rather than applying pressure to the brake calipers. Then, when the
tow vehicle is put into park, neutral or a forward gear the solenoid
returns to its original position allowing the brakes to function nor-
mally during travel.
