Brake System (Common to Hydraulic and Electric)
ASBESTOS DUST HAZARD!
Since some brake shoe friction materials contain asbestos, certain pre-
cautions 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.)
RISK OF PERSONAL INJURY!
Whenever it becomes necessary to jack the trailer it is up to you to
ensure that the trailer or axle is supported securely. Use blocks or jack
stands on solid ground, especially if you are going to be working under
the trailer.
Brake Adjustment
Brakes should be adjusted (1) after the first 200 miles of operation when the brake
shoes and drums have ‘seated’, (2) at 3000 mile intervals, (3) and as use and perfor-
mance requires. Adjust the brakes as follows:
1. Jack up the wheel to be adjusted. Support the raised wheel securely.
2. Remove the adjusting hole cover from the adjusting slot on the bottom of the
brake backing plate.
3. With a screwdriver or a brake adjusting tool, rotate the starwheel of the adjuster
assembly to expand the brake shoes. Adjust the brake shoes until the pressure of the
linings against the drums makes the wheel very difficult to turn.
4. Now rotate the starwheel in the opposite direction until the wheel turns freely with
a slight lining drag.
