" electric brakes have a self adjusting feature. If
manual adjusting is required, use the following procedure:
Brakes should be adjusted (1) after the first 200 miles of
operation when the brake shoes and drums have “seated,” (2) at
3,000 mile intervals, (3) or as use and performance requires. The
brakes should be adjusted in the following manner:
1. Jack up trailer and secure on adequate capacity jack
stands. Follow trailer manufacturer's recommendations for
lifting and supporting the unit. Make sure the wheel and
drum rotates freely.
!
CAUTION
Do not lift or support the trailer on any part of the axle or
suspension system. Never go under any trailer unless it
is properly supported on jack stands which have been
rated for the load. Improperly supported vehicles can fall
unexpectedly and cause serious injury or death.
2. Remove the adjusting hole cover from the adjusting slot on
the bottom of the brake backing plate.
3. With a 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 difficult to
turn.
4. Then rotate the starwheel in the opposite direction until the
wheel turns freely with a slight lining drag.
5. Replace the adjusting hole cover and lower the wheel to the
ground.
6. Repeat the above procedure on all brakes. For best results,
the brakes should all be set at the same clearance.
