Brake Adjustment
Brakes should be adjusted (1) after the fi rst 200
miles of operation after the brake shoes and
drums have “seated”, (2) at 3000 mile intervals
and (3) as use and performance require. The
brakes should be adjusted in the following
manner:
1. Jack up trailer and secure on adequate capacity jack
stands. Check that wheel and drum rotate freely.
2. Remove adjusting hole cover from adjusting slot on
bottom of brake backing plate.
3. With screwdriver or standard adjusting tool, rotate
the starwheel of the adjuster assembly to expand
the brake shoes. Adjust the brake shoes out until
the pressure of the linings against the drum makes
the wheel very diffi cult to turn.
NOTE:
With drop spindle axles, a modifi ed adjusting
tool with about an 80 degree angle should be used.
4. Then rotate starwheel in opposite direction until
wheel turns freely with slight lining drag.
5. Replace the adjusting hole cover and lower wheel
to ground.
6.
Repeat above procedure on all brakes.
CAUTION: Never crawl under your
trailer unless it is resting on properly
placed jack stands.
Do not lift or place supports on any part of
the suspension system.
Brake Cleaning &
Inspection
Y
our trailer brakes must be inspected and ser-
viced at yearly intervals or more often as use
and performance require. Magnets and shoes
must be changed when they become worn or
scored thereby preventing inadequate vehicle
braking.
Clean the backing plate, magnet arm, magnet and
brake shoes. Make certain that all the
parts removed are replaced in the same
brake and drum assembly. Inspect the
magnet arm for any loose or worn parts.
Check shoe return springs, hold down springs
and adjuster springs for stretch or deformation
and replace if required.
CAUTION: Asbestos Dust Hazard. Since
some brake shoe friction materials con-
tain asbestos, certain
precautions need to be taken when ser-
vicing brakes:
1. Avoid creating or breathing dust.
2. Avoid machining, fi ling or grinding the brake linings.
3. Do not use compressed air or dry brushing for clean-
ing. (Dust can be removed with a damp brush).
TRAILER STORAGE
Preparation
If your trailer is to be stored for an extended period
of time or over the winter, it is important that
the trailer be prepared properly.
1. Remove the emergency breakaway battery and store
inside, out of the weather. Charge the battery at least
every 90 days.
2. Jack up the trailer and place jack stands under trailer
frame so that the weight will be off the tires. Never
jack up or place jack stands on the axle tube or on
the equalizers.
3. Lubricate mechanical moving parts that are exposed
to weather, such as the hitch and suspension parts.
NOTE: On oil lubricated hubs the upper part of the
roller bearings are not immersed in oil and are
subject to potential corrosion. For maximum
bearing life it is recommended that you revolve
your wheels periodically (every 2-3 weeks) dur-
ing periods of prolonged storage.
After Prolonged Storage — Inspection Procedures
Before removing trailer from jack stands:
1. Remove all wheels and hubs or brake drums. Note
which spindle and brake that the drum was removed
from so that it can be reinstalled in the same location.
2. Inspect suspension for wear.
3. Check tightness of hanger bolt, shackle bolt and
U-bolt nuts per recommended torque values.
4. Check brake linings, brake drums and armature faces
for excessive wear or scoring.
5. Check brake magnets with an ohmmeter. The
magnets should check 3.2 ohms. If shorted or worn
excessively, replace.
6. Lubricate all brake moving parts using a high temper-
ature brake lubricant. (LUBRIPLATE or equivalent).
CAUTION: Do not get grease or oil on
brake linings or magnet face.
7. Remove any rust from braking surface and armature
surface of drums with fi ne emery paper or crocus
cloth. Protect bearings from contamination while so
doing.
8. Inspect oil or grease seals for wear or nicks. Replace
if necessary.
9. Lubricate hub bearings. Refer to procedure in manual.
10. Reinstall hubs and adjust bearing per instructions in
manual.
