WARNING
To prevent serious eye injury, always wear safe
eye protection when you perform vehicle
maintenance or service.
Park the vehicle on a level surface. Block the
wheels to prevent the vehicle from moving.
Support the vehicle with safety stands. Do not
work under a vehicle supported only by jacks.
Jacks can slip and fall over. Serious personal injury
can result.
Remove all pressure from the air system before
you disconnect any components. Pressurized air
can cause serious personal injury.
When you work on a spring chamber, carefully
follow the service instructions of the chamber
manufacturer. Sudden release of a compressed
spring can cause serious personal injury.
ASBESTOS AND NON-ASBESTOS
FIBERS WARNING
Some brake linings contain asbestos fibers, a
cancer and lung disease hazard. Some brake
linings contain non-asbestos fibers, whose
long-term effects to health are unknown. You
must use caution when you handle both asbestos
and non-asbestos materials.
Remove the Brake Shoes
WARNING
When you work on a spring chamber, carefully
follow the service instructions of the chamber
