Foot-Operated Controls
Service Brake Pedal
This vehicle is equipped with a dual braking
system, the front brakes being independent of
the rear brakes.
Normally both systems are
activated by the single brake pedal. This brake
system becomes a modulated emergency
system if a pressure drop occurs in the rear
brake system.
Service brakes are applied by depressing the
brake pedal, the rate of braking varying
according to the gradual increase of pressure
until the required rate of braking is obtained.
When brake pedal is depressed, vehicle
stoplights automatically light up.
For system information, see "BRAKES" on page
3-1.
Accelerator Pedal
Controls engine rpm.
Note:
Pedal will be inoperative when the
"DDEC-TEST" switch in steering compartment is
in the "ON" position.
Combination Emergency and
Parking Brakes
The spring-loaded, manually operated parking
brake is activated by pulling up on the control
valve knob located on L.H. lateral console (see
item #4 on page 2-4).
This same brake system will automatically be
applied in an emergency situation, whenever the
control valve supply pressure drops below 40
psi (275 kPa).
For system information, see "BRAKES" on page
3-1.
