BRAKE LINE
Locate the brass brake line coupling. Remove the
plastic cap and thread the brake line hose coming
out the rear of the tongue into one end of the
coupling. Bend the line in a smooth gradual radius
being careful not to kink the line. Bend so it can be
mated to the brake line hose from the side frame.
Once aligned, thread the side frame brake line hose
into the other end of the coupling. Tighten both lines
into the coupling.
ROCKER ARMS
Locate the rocker arms (Ref. No. 6 of Detail A in
Diagram D. Note that the center bushing has a
grease zerk in it. Position the rocker arms up into
the center channel welded in the center of the
tandem spring bracket so that the grease zerk is
pointing down. Align the holes in the channel with
the rocker arm. Secure in place with a 3/4” x 4-1/2”
hex bolt and lock nut. Tighten. Repeat this process
on the other rocker arm and spring bracket. Grease
the rocker at this time by applying grease through
the zerk just discussed.
NOTE: The grease zerk is positioned down so
that it is accessible for servicing when needed.
SPRINGS
Position the axles so they are properly aligned with
the trailer. Position the brake axle so that the disc
brake calipers are on the back side of the axle. The
brake axle must always be mounted as the rear
axle to give you the best braking possible (See
Diagram D. There is no right and left to the axle
without brakes. It can be mounted either way.
Place the springs on the topside of the spring pads
welded to the axle. (See chassis diagram). Note
that the hook end of the spring must be to the rear
of the trailer. Place a spring clamp on the top center
of the spring as shown. Next place the 1/2” x 6-1/2”
U-bolts down over the top of the spring clamp,
spring and axle as shown.
Place the spring and axle U-bolt plate onto the ends
of the two U-bolts just placed. Secure in place with
1/2” lock nuts. Thread onto the U-bolts but do not
tighten securely until the complete unit is in position
on the trailer. Repeat on the other spring.
AXLE
Place one of the spring bracket bushings into the
rear of the spring bracket and secure with a 9/16” x
3-1/4” hex bolt and hex lock nut. Repeat in other
spring bracket.
Position the rear axle under the frame, then hook the
loop of the springs around the bushings just
installed. Note that if the axle is positioned too low
when trying to hook, the loops will not hook around
the bushings.
Raise the front of the springs up so they align with
the rear hole in the axle boogie just installed. Secure
in place with 9/16” x 3-1/4” hex bolts and lock nuts.
Install another spring bracket bushing in the front
hole on the rock arm assemblies. Secure with a
9/16” x 3-1/4” hex bolt and lock nut. Tighten.
Hook the hook end of the springs mounted to the
front axle over the bushing just installed in the rocker
arm assembly. Then swing the front of the spring up
and attach the front mounting hole in the spring
bracket with another 9/16” x 3-1/4” hex bolt and lock
nut.
Tighten all axle U-bolts and spring bolts.
ONE AXLE BRAKE INSTALLATION
Cut the tape securing the brake line hose to the axle.
Remove the plastic plug from the bottom port in the
brass block on both brake calipers. Thread in the
brake hose male end and tighten to either 6-8 ft. lb.
or 72-96 in. lb. of torque.
DO NOT OVER TIGHTEN
Over tightening will cause the brass block to crack
and or the threads to release and then leak.
Remove the plastic cap from the end of the frame
brake line coming out of the side frame by the axle.
Carefully pull the brake line hose so that it will thread
thru the brake line bracket. Thread the brake line
hose into the side port on the right side brake caliper.
Tighten.
NOTE: The complete brake system including the
axle MUST be re-bled to ensure that all air has been
removed from the brake system. For bleeding
instructions see the UFP brake bleeding manual or
the ShoreLand’r Disc Brake Manual.
Fill the actuator reservoir with brake fluid and bleed
the line per the instructions in the Brake Manual.
