increase sensitivity to really pinpoint the location
of even a small leak.
" Many fleets use this tool to perform regular
inspections of a truck's air system, " Hawkins
said. " Technicians appreciate the automated
test. They can push a button to start the test
and then walk away to do something else. The
automated system also removes any potential
human error when searching
for air leaks. "
Hawkins
alluded
to
today's modern heavy duty
vehicles and the challenges
they present to technicians.
" Beneath a heavy duty
vehicle frame today, you
have bundles of hoses and
hundreds of connections, "
Hawkins said. " Unless he or
she can see or hear it, a technician
really has no idea where
a leak might be. With modern
trucks, five or six pinhole leaks
on various lines or connections
can cause a large gross
leak that results in a truck not
passing inspection. "
ZF's Brodie said the first
step to efficiently repairing
an air brake system leak is
to accurately diagnose valve
exhaust port leaks.
" During repair, make
sure to install fittings and
route lines according to the
manufacturer
recommendations, "
Brodie pointed out.
" Also, make sure to complete
proactive maintenance like
replacing air dryer cartridges
annually and with original
equipment to mitigate corrosion
caused by moisture finding
its way downstream. "
If addressing an air brake
system leak requires the technician
to cut the brake hose,
Bendix's Nagel said it is very
important to make as precise
a cut as possible.
" You don't want a jagged cut
or something at a 45-degree
angle, " Nagel pointed out.
" There are specialty tools
out there to help make these
brake line cuts. They are well
worth the investment. "
Anything that can give
technicians an advantage
in finding air brake leaks is
a good investment - especially
considering how brake
systems continue to be the
top cause for roadside inspection
failures.
