* Hendrickson offers a minimum one-year, standard service wheel-end system on all ADB packages.
** WABCO PAN19 is not available with HXL7® wheel-end package.
NOTE: All long-life packages do not include wearable items such as rotors and brake pads. If service to these items is necessary within
the warranty period and would require removal of the hub cap (i.e. rotor replacement), Hendrickson must be notified prior to initiation
of the service. If service is performed to Hendrickson's specifications, Hendrickson will continue to warrant the system for the remainder
of the original warranty period.

APPLICATION GUIDE — HENDRICKSON AIR DISC BRAKES
AIR DISC BRAKE WARRANTY
AIR DISC BRAKE PACKAGE WEIGHTS
COMPARED TO DRUM BRAKES
Hendrickson MAXX22T™ air disc brake packages
installed by Hendrickson will carry a limited five-year
parts and one-year labor warranty, excluding all
normal wear. Other air disc brake packages installed by
Hendrickson will carry a limited one-year parts
and labor warranty, excluding all normal wear.
ADB package weights have closed the gap on drum
brake package weights. The following tables show
how several Hendrickson ADB packages compare to
16.5" × 7" and 16.5" × 8-5/8" drum brake packages.
The results are listed as the difference in weight (lbs. /axle).
The wheel-end warranties for ADB cover the hub seal,
bearings and hubcaps.
As shown with an AANT integrated suspension system,
several ADB packages are lighter than drum brakes.
The lightest ADB package using Dura-Light hubs/cast
rotors is nearly identical (2 lbs/axle) to the lightest
16.5" × 7" drum brake with Dura-Light hubs and
Stemco CentriFuse brake drums. This analysis
assumes 10-stud, 11.25" BC hubs using long studs
for aluminum wheels.
For complete information on Hendrickson warranty
policies, refer to literature number, L583 – Hendrickson
Comprehensive Warranty Statement available online
at www.hendrickson-intl.com.
R NOTE:
Warranty coverage from our air disc brake
suppliers is subject to change without
notice. Always contact the air disc brake
supplier for the most current warranty
information and specific details regarding
coverage of air disc brake parts.
CLOSING
ADB is an evolving technology for the NAFTA market
and changes are occurring rapidly. As new developments
arise, Hendrickson will continue to provide updated
information.
For questions regarding air disc brake packages at
Hendrickson, please notify your trailer account manager
or call 1-866-RIDE-AIR (866-743-3247) and ask to speak

* Actual weights may vary depending on suspension selection specification.
NOTE: Due to configurations that are required to package air disc brakes on AANL suspensions, such as rear mounted shocks, the weight
savings for AANL air disc brakes are not as significant as on other suspension types. Estimated weight differences for AANL drum and
disc suspensions are show in the table on page 10.
