Brake Cleaning and Inspection
Your trailer brakes must be inspected and serviced immediately if a loss of
performance is indicated. With normal use, servicing at one year intervals
is usually adequate. With increased usage, this work should be done more
frequently as required. Magnets and shoes must be changed when they become
excessively worn or scored, a condition which can reduce 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 for any loose or worn parts, stretched or deformed springs and replace
as necessary.
CAUTION
POTENTIAL ASBESTOS DUST HAZARD!
Some older brake linings may contain asbestos dust, which has been
linked to serious or fatal illnesses. 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).
Brake Lubrication
Before reassembling, apply a light lm of grease or anti-seize compound on
the brake anchor pin, the actuating arm bushing and pin, and the areas on the
backing plate that are in contact with the brake shoes and magnet lever arm.
Apply a light lm of grease on the actuating block mounted on the actuating
arm.
CAUTION
Do not get grease or oil on the brake linings, drums or magnets.
