5.0.1 GENERAL INFORMATION ABOUT
BENDIX
® AIR DISC BRAKE MAINTENANCE
When working on Bendix ® Air Disc brakes, please note
the following:
• Read and follow the Safe Maintenance Practices on
page two.
• Depending on the particular axle, the technician may
need to remove the caliper/carrier to allow suffi cient
access to perform the work.
• CAUTION: When using a hoist to support the air
disc brake, do not attempt to use the pad retainer
bar as a bracing point as it is not designed to
support the weight of the brake. Instead use a
brace (or chain) wrapped around the entire brake
to attach the hoist.

TABLE 3 - OTHER REQUIRED SECTIONS FOR MAINTENANCE KITS
• When replacing bearings — or for any other
maintenance procedure where the technician needs
to remove the caliper/carrier assembly from the vehicle
to perform the maintenance —
replacement caliper/
carrier bolts will be required. Please note that due
to the high torque required, the original bolts cannot
be reused. The bolts are available from the vehicle
manufacturer.
• WARNING: Not all wheels and valve stems are
compatible with Bendix Air Disc Brakes. Use only
wheels and valve stems approved by the vehicle
manufacturer to avoid risk of valve stem shear and
other compatibility issues.
