LEAKAGE DEFINITIONS
It is necessary for you to know how fluid leaks affect the status of the trailer. The following are
definitions of the types/classes of leakage needed to determine the status of the trailer. Become
familiar with them. When in doubt, notify your supervisor.
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 Ill Leakage of fluid great enough to form drops that fall.
CAUTION
Equipment operation is allowed with minor leaks (Class I or Class 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 Ill leaks must be reported to your supervisor or organizational maintenance.
