Disc Inspection
Checking the disc is important; it must be perfectly clean, with no sign of rust, oil or grease or other dirt
and must not show signs of deep scoring.
Characteristic
New rear disc thickness
4.0 mm
Disc thickness at wear limit (front)
3.5 mm
•
Using the appropriate tool, measure
how much the disc protrudes when the
wheel is fitted properly. The protrusion,
measured near the external edge of
the disc, must be less than 0.1 mm.
•
If a value is measured other than the
specified value, remove the front wheel
(Front/Rear Suspension chapter) and
check the protrusion of the disc. Maxi-
mum permissible out of true is 0.1 mm.
If the value measured is greater, re-
place the disc and repeat the check.
•
If the problem persists, check and re-
place the wheel hub if necessary.
