NOTE: With drop spindle axles, a modified
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
Your trailer brakes must be inspected and serviced 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 inad-
equate vehicle braking.
Clean the backing plate, magnet arm, magnet and brake
shoes. Make certain that all the parts removed are re-
placed 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 contain asbestos, certain
precautions need to be taken when
servicing brakes:
1. Avoid creating or breathing dust.
2. Avoid machining, filing or grinding the brake linings.
3. Do not use compressed air or dry brushing for
cleaning. (Dust can be removed with a damp brush).
TOWING INSTRUCTIONS
Before hitching and towing on public roads, check that
the tow vehicle uses a 2-5/16" ball on a hitch rated class
II minimum. Make sure keeper engages ball to secure
hitch. Adjust if necessary.
Vehicle Towing Capacity
Refer to your vehicle owner's manual for listed trailer
towing capacity.
Trailer towing capacity should equal GCWR minus ve-
hicle weight, cargo weight, people weight and vehicle
fluids weight.
Check axle load rotating.
The following two rules may limit your vehicle's towing
capacity and the tank fill level when towed. Determine
towing capacity as described below and follow guide-
lines in using the
lowest value from the 2 rules.
1. Trailer Hitch: Check rating of vehicle's trailer hitch.
Class II — 3,500 lbs. Towing capacity is required.
2. Vehicle GCWR (Gross Combined Weight Rating):
Towing capacity = GCWR minus vehicle weight
minus cargo weight minus passenger weight. The
GCWR is provided on your vehicle or in vehicle
manual.
The hitch jack should always be tilted up when towing
to avoid damage to caster wheel. Pin jack clamp
securely.
Always use safety chains and trailer lights.
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 ex-
posed to weather, such as the hitch and suspen-
sion 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) during periods of prolonged storage.
Inspection Procedures
After Prolonged Storage
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.
