Emergency Information 285
Caging Spring Brake Chambers
The parking spring brake chambers may be
released mechanically if there is no com-
pressed air available.
Always start by chocking the wheels to
prevent the vehicle from rolling. Chock-
ing the wheels is important since you
have to work under the vehicle. Failure
to do so can result in unexpected vehicle
movement and serious personal injury or
death can occur.
In the event of brake system failure,
where the spring chambers are caged, the
vehicle cannot be driven. There would
be no means for stopping the vehicle
and this could result in serious personal
injury or death. Before caging the spring
chambers, make the connection to a tow-
ing vehicle or chock the wheels.
Remove the plastic plug in the front end of
the chamber. Remove the screw from the
holder in the side of the brake chamber. In-
sert the screw into the front hole and push
in until it bottoms. Screw into the cylinder
so at least 4 to 6 threads have entered.
