5.1 AIR DISC BRAKE SHIELD KIT
5.1.1 CAUTION: Follow all safe maintenance
practices, including those listed on page two of
this document. Park the vehicle (by other means
than the foundation brakes) on level ground and
chock the wheels.
Note: Most torque plates manufactured after January 1,
2007 have the required torque plate tabs to permit these
shields to be mounted.
This shield kit includes a brake pad shield, a rotor shield
and the required attaching hardware for use in Bendix
®
ADB22X ™ and ADB22X-V ™ Air Disc Brake applications
where external contamination and excessive road debris is
a concern. Brake pad and rotor shields can greatly reduce
damage and/or premature wear of pads and rotors under
these conditions.
During installation, verify that once the shield(s) are
installed they will not come into contact with any vehicle
components, suspension, housings, etc. through the full
range of motion of the wheel. Keep in mind the particular
use of the vehicle, the orientation of the brake on the axle
and torque plate, the proximity of other axles, and/or the
wheel/tire being used.

5.1.3 Drive or Steer Axle Rotor Shields (See Figure
31). Position the rotor shield between the torque
plate and the rotor. The supplied cap screws
pass through the mounting tabs in the torque plate
and install into the shield. Torque cap screws to
44 Ft. Lbs. (528 in. lbs.).
5.1.4 Trailer Axle Rotor Shields (See Figure 32).
Position the rotor shield with the torque plate
between the shield and the rotor. With one
(supplied) lock washer in place on each cap screw,
pass the screws through the shield before mounting
onto the threaded torque plate holes. Torque the
cap screws to 24 ft. lbs. (288 in. lbs.).
Note: The installation of air disc brake shields does not
eliminate the need for periodic maintenance and inspection
of the air disc brake and entire wheel end for damage and/
or wear. In addition, the truck and trailer manufacturer’s
specifi c criteria for the brake shield requirements on air
disc brakes should be consulted before either installing or
removing air disc brake shields from a wheel end(s).
