including drums, wheel cylinders,
calipers, parking brake, master
cylinder, brake fluid reservoir,
vacuum pipes, electric vacuum
pump including bracket and vent
hose, if equipped.

Visually inspect steering,
suspension, and chassis
components for damaged, loose,
or missing parts or signs of wear at
least once a year.
Inspect power steering for proper
hook-up, binding, leaks, cracks,
