2.0 PREVENTIVE MAINTENANCE
Regular inspection and maintenance of air disc brake
components is an important part of vehicle maintenance.
The maintenance practices outlined here are recommended
in addition to all standard industry practices (including
daily pre-trip inspections.) Also, see the vehicle's manual
for recommendations. Keep track of the results of your
maintenance inspections to assist you in determining the
ideal maintenance intervals for the vehicle.
Use the table below for a guide to maintenance interval
planning, however, depending on the particular vehicle's
use, more frequent checks of the components may be
necessary.
