Maintenance and Adjustment
Brakes
1. Lining material thickness
2. 1.5 mm (0.06 in) groove thickness
Brake Pad Wear Inspection
Brake pads must be inspected in accordance
with the scheduled maintenance
requirements and replaced if worn to, or
beyond, the minimum service thickness.
If the lining thickness of any pad (front or rear
brakes) is less than 1.5 mm (0.06 in), that is, if
the pad has worn down to the bottom of the
grooves, replace all the pads on the wheel.
Breaking-in New Brake Pads and
Discs
After replacement brake discs and/or pads
have been fitted to the motorcycle, we
recommend a period of careful breaking-in
that will optimise the performance and
longevity of the discs and pads. The
recommended distance for breaking-in new
pads and discs is 200 miles (300 km).
After fitting new brake discs and/or pads
avoid extreme braking, ride with caution and
allow for greater braking distances during the
breaking-in period.

Warning
Brake pads must always be replaced as a
wheel set. At the front, where two calipers
may be fitted on the same wheel, replace
all the brake pads in both calipers.
Replacing individual pads will reduce
braking efficiency and may cause loss of
motorcycle control and an accident.
After replacement pads have been fitted,
ride with extreme caution until the new
pads have 'broken in'.
