TM 9-2330-231-14&P
LEAKAGE DEFINITIONS - CONTINUED
Class I - Seepage of fluid (indicated by wetness or discoloration) not great enough to form drops.
Class II - Leakage of fluid great enough to form drops, but not enough to cause drops to fall.
Class III - Leakage of fluid great enough to form drops that fall.
CAUTION
Equipment operation is allowable with minor leaks (class I and II). Consideration
must be given to the fluid capacity of the trailer hydraulic system. When in doubt,
notify your supervisor.
When operating with class I or II leaks, check fluid levels more often than required
in the PMCS. Hydraulic brake systems with leaks will stop working if fluid levels
are not maintained.
Class III leaks should be reported to your supervisor or organizational
maintenance.
