1.1. Emergency/parking Brake &
Check Valve Integrity Test (40 ft.
Vehicle)
☞NOTE:
The following procedure will test the operation
of the parkinging brake system, emergency
brake system, and emergency
brake release system (where equipped).
This procedure will simulate vehicle operation
in emergency mode with loss of air
supply at one or more tanks. Perform these
tests in the sequence listed in order to
avoid duplicate or redundant testing.
1. parking the vehicle on level ground and
chock the wheels.
2. Start the engine and charge the air system
to cut-out pressure.
3. Stop the engine.
4. Ensure the wheels of the vehicle are
chocked and release the parking brake.
5. Drain the wet tank. The front and rear
brake tanks should retain full pressure.
☞NOTE:
Refer to the General Information Section of
your New Flyer Service Manual for tank
draining procedures and location of air
tank drain valves.
6. Drain the front axle brake tank. The low air
warning lamp on the front brake tank
gauge should illuminate and the low air
buzzer should sound. The rear brake tank
should retain full pressure.
7. With no air pressure in the front brake
tank, make a service brake application.
The rear axle brakes should apply and the
rear brake lamps should illuminate.
8. Slowly drain the rear axle brake tank. The
parkinging brake control valve should pop
to the applied position when the rear reservoir
reaches approximately 45 psi.
☞NOTE:
DO NOT use the brake treadle to bleed
down the axle brake tanks. Rapid pumping
of the brake treadle will cause pressure
pulsations that can result in premature
application of the spring brakes, resulting
in a false pressure reading.
☞NOTE:
Ensure that the interlocks are NOT applied
when bleeding down the system.
☞NOTE:
The following step applies to vehicles
equipped with an Emergency Brake
Release (EBR) valve. Otherwise, proceed
to step 10.
9. Actuate the emergency brake release control
by pressing and holding the knob in the
down position. The parking brakes at the
rear axle should release and remain
released as long as the control is held in
the down position. Release the control.
The parking brakes at the rear axle should
reapply. Repeat this cycle until the parking
brakes fail to release. Drain the emergency
brake release tank. The parking brakes
should remain in the applied position.
10.Close all tank drain valves, start the
engine, and recharge the air system to cutout
pressure.
11.Stop the engine and release the parking
brake.
12.Drain the rear axle brake tank. The low air
warning lamp on the rear brake tank gauge
should illuminate and the low air buzzer
should sound. The front brake tank should
retain full pressure
13.With no air pressure in the rear brake tank,
make a service brake application. The
front and rear axle brakes should apply
and release at least once, the rear brake
lamps should illuminate, and the parking
brake should remain released.

14.Test is complete. Close all reservoir drain
valves, start the engine, and recharge the
air system to cut-out pressure.
15.If the brakes do not operate as described
in the test procedure, check the following
for leakage and correct as required:
a. Fittings.
b. Kinked lines.
c. Single check valves.
d. Double check valves.
e. parkinging brake control valve.
f. Emergency release valve (if equipped).
g. Brake relay valve.
h. Spring brake modulating valve.
i. Brake foot valve.
j. ABS modulator valves.
k. ATC valve (if equipped).

1.2. Emergency/parking Brake &
Check Valve Integrity Test (60 ft.
Vehicle)
☞NOTE:
The following procedure will test the operation
of the parkinging brake system, emergency
brake system, and emergency
brake release system (where equipped).
This procedure will simulate vehicle operation
in emergency mode with loss of air
supply at one or more tanks. Perform these
tests in the sequence listed in order to
avoid duplicate or redundant testing.
1. parking the vehicle on level ground and
chock the wheels.
2. Start the engine and charge the air system
to cut-out pressure.
3. Stop the engine.
4. Ensure the wheels of the vehicle are
chocked and release the parking brake.
5. Drain the wet tank. The front, center and
rear brake tanks should retain full pressure.
☞NOTE:
Refer to the General Information Section of
your New Flyer Service Manual for tank
draining procedures and location of air
tank drain valves.
6. Drain the front axle brake tank. The low air
warning lamp on the front brake tank
gauge should illuminate and the low air
buzzer should sound. The center and rear
brake tanks should retain full pressure.
7. With no air pressure in the front brake
tank, make a service brake application.
The center and rear axle brakes should
apply and release at least once and the
rear brake lamps should illuminate.
8. Drain the rear axle brake tank. The center
brake tank should retain full pressure.
9. Slowly drain the center axle brake tank.
The parkinging brake control valve should
pop to the applied position when the center
reservoir reaches approximately 45 psi.
☞NOTE:
DO NOT use the brake treadle to bleed
down the center axle brake tank. Rapid
pumping of the brake treadle will cause
pressure pulsations that can result in premature
application of the spring brakes,
resulting in a false pressure reading.
☞NOTE:
The following step applies to vehicles
equipped with an Emergency Brake
Release (EBR) valve. Otherwise, proceed
to step 11.
10.Actuate the Emergency Brake Release
control by pressing and holding the knob in
the down position. The parking brakes at
both center and rear axles should release
and remain released as long as the control
is held in the down position. Release the
control. The parking brakes at both center
and rear axles should reapply. Repeat this
cycle until the parking brakes fail to
release. Drain the emergency brake
release tank. The parking brakes should
remain in the applied position.
11.Close all tank drain valves, start the
engine, and recharge the air system to cutout
pressure.
12.Stop the engine and release the parking
brake.
13.Drain the center axle brake tank. The low
air warning lamp on the center brake tank
gauge should illuminate and the low air
buzzer should sound. The front and rear
brake tanks should retain full pressure.
14.With no air pressure in the center brake
tank, make a service brake application.
The front and rear axle brakes should
apply and release at least once and the
rear brake lamps should illuminate.
15.IIf the parking brakes applied in the previous
step, verify that the emergency brake
release (if equipped) is capable of releasing
the parking brakes and that the parking
brakes reapply when the control is
released.
16.Verify that the parking brakes at both center
and rear axles release when the parking
brake control valve is in the released
position.
17.With the parking brakes released, make
another service brake application and verify
that the front, center and rear brakes
apply at least one more time.
