perators, the brake indicator light
on the SEE’s dashboard lets you know
when:
brake fluid in the reservoir is low
the parking brake is ON
the vehicle’s front brake pads are
worn.
Problem is, the pads can be worn
dangerously close to the brake drums
and you won’t even know it!
Construction opera-
tions in heavy brush can
damage the indicator’s
brake line where it
mounts into the brake
pad’s caliper housing. If
it is torn off or damaged,
you’ve got a disconnect
with the indicator’s send-

Before operation is a good time to
do the extra checks. If you see rust, or
if a fitting appears dry, lube it. Always
wipe off the excess lube so it won’t
collect dirt. After lubing, launch the
bridge to evenly distribute the lube.
Then lube again.

mounts into the caliper housing. If the
line looks damaged, torn or dangling,
report it.
Man, I hope
the brake indicator
line didn’t get
torn off!

o keep your AVLB lubed, you have
to follow LO 5-5420-202-12, but that’s
not all.
Minimum lube intervals are based
on an AVLB that is launched about
four times a month.
Lube more often with more launches,
or if you are operating in rain, heat or
dust. Any squeaking pin also needs to
be found and lubed.
Without grease, bearings burn out or
seize. If a bearing seizes, something
breaks.
A rusty color or powdery substance
around a hinge point means it needs
lube. Loud or excessive squeaking of
