NOTICE
NHTSA Safety Corrosion Alert
NHTSA has warned all vehicle own
-
ers of all brands that they must
maintain their vehicles in a manner
which will prevent brake hose and
brake line failures due to corrosion
when such vehicles are exposed to
winter road salt and related chemi
-
cals. While serious corrosion condi
-
tions typically only manifest
themselves as safety issues after 7
years of vehicle use, the corrosion
process starts immediately and
thus underbody cleaning mainte
-
nance must commence from your
vehicle's first exposure to road salts
and chemicals. NHTSA urges vehicle
owners to take the following steps
to prevent corrosion:
1. Wash the undercarriage of your
vehicle regularly throughout the
winter and do a thorough washing
in the spring to remove road salt
and other de-icing chemicals.
2. Monitor the brake system for
signs of corrosion by having regu
-
lar professional inspections and
watching for signs of problems,
including loss of brake fluid,
unusual leaks and soft or spongy
feel in the brake pedal.
3. Replace the entire brake pipe
assembly if you find severe corro
-
sion that causes scaling or flaking
of brake components.
