One Axle Brake Installation

Cut the tape securing the brake hose to the axle. Remove the
plastic plug from the bottom port in the brass block on the right
brake caliper. Thread in the male end of the brake hose and
tighten. Repeat the process on the other side of the trailer
removing the plastic cap from the side port on the left caliper.
Insert the threaded end of the brake hose and tighten. Remove
the plastic cap from the end of the frame brake hose. This brake
hose is located coming out of the black plastic tube in the side
frame by the axle. Uncoil the brake hose so that it can be routed
thru the brake line clip bracket. Thread the side frame brake hose
into the side port of the right caliper. Tighten. Place a grommet
around the brake hose and insert in the brake line clip to protect
the frame brake hose. NOTE: Bleeding of the system should be
done through the bleeder on the left caliper.

Fill the actuator reservoir with brake fluid and bleed the line per
the instructions in the Brake Manual. All bleeding of the system
should be done through the bleeder on the left caliper.

For bleeding instructions see the ShoreLand’r Disc Brake Manual.

DUAL AXLE BRAKE INSTALLATION

Cut the tape securing the brake hose to the axle. Remove the plastic plug from the bottom port
in the brass block on the right brake caliper. Thread the brake hose male end into the block

and tighten. Repeat the
process on the other side of the
trailer removing the plastic cap
from the side port on the left
caliper. Insert the threaded end
of the brake hose and tighten.
Attach the male/female brake
hose from the brake kit into the
side port on the brass block on
the right caliper. Attach the
brake hose from the axle to the
spring bracket with the brake
line clip bracket as shown.
Once the brake hose is secured
with the hose clips, locate the
brass tee connector. Screw the
male port of the tee into the
brake line hose. Tighten.
Connect the side frame brake
hose into the top port on the
tee. Connect the two axles

brass tee. Route the hose over to and thru the brake line clip above the other axle. Connect
the other end into the side port of the right caliper on the second axle. Place a grommet around
the hose and insert into the brake line clip. To keep excess line up out of the way make a loop
in the 42” line and secure to the side frame with the clips included in the kit.

Fill the actuator reservoir with brake fluid and bleed the line per the instructions in the
ShoreLand’r Disc Brake Manual. Bleeding the system should be done through the bleeder
on the left caliper.

BUNK ASSEMBLY

Locate the two 2 x 6 bunk assemblies. Note that the bunk mounting brackets are assembled at

factory. Place the end with the two brackets towards the rear of the trailer. Place the

assembly

on the equiload bunk arm and secure by placing a 3/8” x 1” hex bolt through the bracket on the
bunk and the ear on each end of the equiload arm. Secure in place using a 3/8” lock nut.
Repeat on the other end of the arm.

Midwest Industries, Inc. Ida Grove, IA 51445 800-859-3028 www.shorelandr.com 0004297
Page 8 of 11 2/09/2011

The front bracket is not attached to the bunk because the trailer can be adjusted to two

different lengths. Once the proper
position for the rear cross member is
determined, the front of the bunk can
now be attached to the bracket using
two- No. 10 x 1-1/4” self tapping screws.
The 3/8” bolts can be tightened but not
over tightened because the bunks
should be allowed to rotate slightly to
conform to the boat’s bottom.

Tire and Wheel Assemblies

Mount the tire and wheel assemblies using the 1/2” fine threaded tapered lug nuts provided.
Tighten to 80-90 ft/lb. of torque using the rotation pattern as shown in the ShoreLandr’s

Owners Manual.

Re-torque the lug nuts after 50 miles of driving and then periodically thereafter.
Refer to the tire side wall for correct tire pressure.

NOTE: All nuts and bolts must be tightened before towing.

TRAILER ADJUSTMENTS
Axle Adjustment

The amount of tongue weight on your trailer can be adjusted as follows: To lower the tongue
weight, adjust the axle assembly forward. To increase the tongue weight, adjust the axle
assembly backward. The distance that the axle assembly has to be moved will vary because it
is directly related to the weight and center of gravity of the boat place on it. Best towing is
achieved when the tongue weight is 5-7% of the total gross load of the complete unit.

NOTE: Brake line and wire harness will need care when moving the assembly.
Rear Support System

Place the boat on the trailer so that the transom is located at the rear of the support system.
On a bunk trailer, the transom of the boat should be within 1-2” of the end of the bunk. This
gives you maximum support on the transom.
The rear cross member is adjustable
forward or backward to allow the trailer to
be adjusted to various length boats. This
is accomplished by removing the pivot bolt
on each end that holds the rear pivot arm
to the side frame and the rear pivot offset
weldments.
Once the rear pivot arm assembly is
removed, remove the two additional bolts
on each side frame that mount the rear pivot offset weldments to the side frame. Move them to
the desired location and remount to the side frames with the bolts just removed. Reposition the
rear pivot arm between the two rear pivot offset weldments just installed. Secure in place using
the two pivot bolts removed earlier. Tighten. The wire harness for the three-light identification
light must be re-positioned where it comes from the black wire harness tubing to eliminate
slack, and sagging of the wiring.

Bunks
The bunks must be positioned far enough apart to give your boat as much stability as possible
while transporting. Position the bunks so they are located just to the outside of the boat’s
strake. This will help center your boat and assist when loading. The bunks need to be adjusted
up high enough to keep the keel from resting on the center pads. A minimum of 1” to 2” of
clearance is desirable.

Winch Post/Bow-eye

Slide the winch post base backward on the tongue until the bow roller comes in contact with
the boat. The bow roller needs to be positioned directly above the boat bow eye to prevent
your boat from moving forward in the event of a sudden stop. It can be moved up or down by
removing the back bolt that mounts the winch head to the base. When this bolt is removed, the
head can be rotated up or down to reach the height required to fit your boat. Once in this
position, align the closest pair of holes in the brackets and reinsert the bolt just removed.
Tighten. Attach the winch strap and crank winch tight. Attach the bow eye safety chain into the

Midwest Industries, Inc. Ida Grove, IA 51445 800-859-3028 www.shorelandr.com 0004297

bow eye of the boat as well. This is just another level of protection to keep your boat and trailer
together as one unit.
Adjustments are now complete.

Double check your boat for fit. If desired fit has been achieved, tighten all fasteners that may
have either been left loose or have been loosened to do the adjusting.

Re-check all fasteners on the complete trailer to make sure they are all tight and ready for
towing. All fasteners should be periodically checked before towing.

See your ShoreLand’r Owner’s Guide for further technical information regarding your trailer
and its components.
