Inspect all flexible hydraulic brake
hoses for bulges, pinches, cracks,
crimping, chafing, abrasions, or leaks. If
any of these conditions exist, replace or
reposition to prevent failure. Check
front brake hoses (11) for loose or
missing fittings, and ensure they are
long enough to allow full steering travel.
If brake hose (11) is too short, it must be
replaced with new longer hoses
(WP 0175 00 and WP 0176 00).
