WARNING!
Do not disassemble a spring brake cham-
ber. These chambers contain a powerful
spring that is compressed. Sudden release
of this spring may result in death or personal
injury.
WARNING!
Releasing the spring brakes on an unse-
cured vehicle could lead to an accident. The
vehicle could roll, which may result in death,
personal injury, equipment or property dam-
age. Always secure the vehicle with wheel
chocks, chains, or other safe means to pre-
vent 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.
4. Insert the release stud through the
opening in the spring chamber
where the cap was removed. Insert
it into the pressure plate. Turn the
release stud 1/4 turn clockwise in
the pressure plate. This secures the
cross pin into the cross pin area of
the pressure plate and locks it into
the manual release position.
5. Assemble the release stud washer
and nut on the release stud.
