the parking brakes (or Spring Brakes) can
be manually released.
WARNING
Do not drive vehicle with malfunction-
ing brakes. If one of the brake circuits
should become inoperative, braking
distances will increase substantially
and handling characteristics while
braking will be affected. You could lose
control of your vehicle or cause an ac-
cident. Have it towed to the nearest
dealer or qualified repair facility for re-
pair. Failure to comply may result in
death, personal injury, equipment or
property damage.
WARNING
Do not operate a vehicle when the
spring brakes have been manually re-
leased. Driving a vehicle after its
spring brakes are manually released is
extremely dangerous. The brakes may
not function. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
WARNING
Do not disassemble a spring brake
chamber. These chambers contain a
powerful spring that is compressed.
Sudden release of this spring may re-
sult in death or personal injury.
WARNING
Releasing the spring brakes on an un-
secured vehicle could lead to an acci-
dent. The vehicle could roll, which may
result in death, personal injury, equip-
ment or property damage. Always se-
cure the vehicle with wheel chocks,
chains, or other safe means to prevent
rolling before manually releasing the
spring brakes.
To move a vehicle immobilized by the
spring brakes due to loss of air pressure in
the brake system, perform the following
procedure:
1. Remove the cap from the spring
chamber
2. Remove the release stud assembly
from the side pocket, and remove
the release nut and washer from
the release stud.
3. Slide out the release stud.
