WARNING
An auto slack adjuster should never have to
manually adjusted while in service. The only
time it should be manually adjusted is during
installation or at brake relining. By constantly
manually adjusting the hex shaft the internal
clutch life can be shortened. The proper way of
checking an auto slack to see if it is working
within specifications is to measure the working
stroke.
CAUTION
Check the brake adjustment frequently during
the first 500 miles after relining. Overloading or
using only the trailer brakes to stop the
complete tractor-trailer unit will cause the heat
absorption capacity of the brake to be
exceeded. Hotter brake linings and drums,
longer stopping distances, and shorter brake
lining life will result.
