components that have high effort or excessive
wear. Do not lubricate accelerator and cruise
control cables.

Inspect the complete system. Inspect brake lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition. Inspect other
brake parts, including calipers, parking brake,
