Brake Adjustment - Automatic Slack Adjuster
NOTE: A properly working Automatic Slack Adjuster does not require
manual adjustment while in service. The manual adjuster hex is
intended for use during adjuster installation and brake overhaul.
WARNING: Automatic slack adjusters must never be repeatedly
adjusted to correct excessive in service pushrod stroke, because this
condition indicates that a problem exists with the automatic adjuster,
with the installation of the adjuster or with related foundation brake
components which manual adjustment will not correct.
