f you’ve just Fnished brake maintenance, the last thing you want happening to
that HMMWV is brake failure! But it can happen to HMMWVs with serial numbers
299,999 and below if you don’t give them the special attention they need.
Whenever you pull maintenance
on any part of the brake system,
make sure the loop clamp, NSN
5340-01-189-7640, that holds the
brake line to the caliper on the right
side of the vehicle is installed. If
you don’t, you could be super-sorry!
Your HMMWV’s brakes may not
fail right away, but the jostling and
rubbing could eventually lead to a
long walk home.
You’ll Fnd the loop clamp in

Dear Editor,
In my work as a safety officer at Ft Carson, I see units putting cargo, fuel
and water-carrying vehicles and trailers that have heavy secondary loads on
jack stands. These loads could weigh hundreds of pounds.
A jack stand that can safely support an empty truck or trailer may not be
able to carry all the extra weight of the load. And most of the time Soldiers
have no idea how much that extra load weighs. Plus the extra load changes
the center of balance, which means the vehicle could fall off the jack stands.
If a jack stand collapses, someone could be killed.
So I strongly recommend that units unload trucks and trailers
before
they
put them up on jack stands. There is no point in taking chances.

Editor’s note:
Excellent point, Mr. Fenner.
Jack stands are the last thing you want to
take chances with. Always unload your truck
or trailer before putting it on jack stands.
we can handle
a hmmwv with no
problem but it’s
this
extra
load
that’s
killin’
us!
