Brakes 227
From the operator’s viewpoint, operating
the foot brake valve of a vehicle equipped
with air brakes differs very little from the
operation of a conventionally braked vehi-
cle. Because the operation of the brake
pedal requires scarcely more effort than de-
pressing the average throttle pedal, air
brakes are naturally much easier to control.
If the driver gives full attention to the fol-
lowing suggestions, a little experience will
make him/her thoroughly familiar with the
air-controlled braking of this vehicle.
Failure to observe these precautions can
result in loss of vehicle control and seri-
ous personal injury or death can occur.
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 pres-
sure 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.
