INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment.
You may need to have
your brakes inspected more often
if
your driving habits or conditions
result in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also,
if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays
on or
comes on, something may be wrong
with the anti-lock brake system. See
“Anti-Lock Brake System Warning
Light” in the Index.
