Brake Pad Wear
Brake pad wear depends on the severity of usage
and track conditions. (Generally, the pads will
wear faster on wet and dirty tracks) Inspect the
pads at each regular maintenance interval
(page 21).
Front Brake Pads
Inspect the brake pads (1) through the front wheel
to determine the pad wear. If either pad is worn
anywhere to a thickness of 0.04 in (1 mm), both
pads must be replaced.
