Ford F-650 2015 Owner's Manual page 142

A qualified service technician should perform air brake inspection and
adjustment or repairs keeping to the instructions in the service manual.
Cam Brakes - Automatic Slack Adjusters
WARNING: Do not manually adjust the automatic slack adjusters
to correct excessive push rod stroke as it may result in reduced
brake effectiveness and a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the
installation of the adjuster, or with foundation brake components that
manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
Emergency Air Brake
WARNING: Do not continue to operate the vehicle with a failure
of one of the brake systems. Take the vehicle to your dealer for
service immediately.
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system functions for emergency
stopping. The brake pedal controls all these systems in the same manner
as for normal stops.
