5-28.6 Manual Parking Brake Release (Caging Brakes)
Spring brake chambers require air pressure to release. If sufficient pressure is not available and the vehicle must be
towed, the spring brakes can be manually released or “caged.”
To manually release the spring brake chambers, use the caging stud supplied with the spring brake chamber. Insert
the stud into the chamber and turn to engage the stud in the slots. Tighten the nut on the caging stud with a wrench
to compress the spring and release the brake. After the need for caging the brakes has past, charge the spring brake
chambers with air pressure and remove the caging stud.
5-28.7 Emergency Parking Brake Release
(Optional)
The emergency parking brake release option allows the operator to override the parking brake safety feature that
prevents the spring brakes from being released until minimum pressure has been built up in the air brake system.
Air pressure for the spring brake release is supplied by a dedicated air tank.
Caged Brakes Will Not Hold Vehicle.
Never leave a vehicle with caged brakes unattended.
•
Park vehicle on a flat surface only.
•
Chock wheels in both directions.
•
Perform Lockout/Tagout to secure vehicle and make sure no one drives it until repairs are
complete.
Failure to follow these procedures may lead to loss of vehicle control, property damage, personal
injury or death.
To avoid the loss of vehicle control resulting in property damage or personal injury, block the wheels
of the vehicle to prevent motion before attempting to manually release spring brake chambers.
Never attempt to disassemble a spring brake chamber as the release of a powerful spring could result
in severe personal injury or death.
The emergency parking brake release feature allows the vehicle to be driven even though service
brakes may not have sufficient air pressure to enable sustained or full force braking. Never exceed
2 mph with the emergency parking brake release engaged and use extreme caution when operating the
vehicle with either air brake section charged to less than 60 psi, or property damage or personal injury
could result.
