BRAKES
The features of the braking system include a
dual system where the front and rear circuits are
completely independent from each other. The
brakes are Knorr-Bremse air operated disc type
brakes with ABS and automatic slack adjusters
on front drive and tag axles. Model 24/24 spring
brakes on drive axle provide emergency and
parking brakes. Emergency brake application
will be automatic if pressure drops below 40 psi.
At 60 psi a warning light and buzzer will come
on so the driver can bring the vehicle to a safe
stop simply by a conventional application of the
foot brake pedal.

ANTI-LOCK BRAKING SYSTEM (ABS)
The anti-lock braking system has one Electronic
Control Unit (ECU) controlling a four channel
system. One wheel slip sensor is mounted at
each front axle and drive axle wheel. The Tag
axle wheels are slave to the drive axle wheels.
The Electronic Control Unit (ECU) is
maintenance free. Its operating voltage is 24 ± 6
volts DC. The thermal operating range for the
ECM is from -40 to 167°F (-40 to 75°C).
The solenoid control valves are maintenance
free. Their operating voltage is 24 (+4.8, -2.4)
volts DC. The rated current draw is 1.65 amps.
The thermal operating range of the solenoid
control valves is from -40 to 176°F (-40 to 80°C).
