1 The best possible stop will be made
when the first brake application is as
firm as the speed and road condition
permit. Then, ease off as the speed is
reduced. Never apply the brakes lightly
at first and increase the pressure as the
speed diminishes.
2 DO NOT fan the brake pedal. Fanning
gives poor brake performance and
wastes air.
3 The air brake is designed so that when
the brake pedal is fully depressed, an
emergency application results. This
application should be made only in an
emergency situation.
4 In making a stop or a slow-down, allow
the transmission to remain in gear with
the throttle closed, disengaging the
clutch only when engine idling speed
is reached.
5 When parking the vehicle, place the
transmission in neutral and set the
parking brake before shutting down the
engine.
6 When descending a long grade, do not
use the service brakes too long or too
often. The brakes may overheat and
lose their effectiveness.
7 Before descending a steep grade, the
transmission should be shifted into
a lower gear and the vehicle speed
reduced. Other speed retarding devices
should also be used if available (engine
brakes, retarders or trailer hand control
valves).
