hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc.
(b) Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts
or signs of wear. Inspect power steering lines and hoses for proper
