CHECKING THE BRAKE DISC
The following operations must be performed when
the brake disc is installed on the wheel.
Visually check the surface of the brake disc. If it
shows any signs of scoring or damage, replace the
disc (REMOVING THE BRAKE DISC).
Check the wear of the brake disc by measuring its
minimum thickness with a micrometer at several
points.
If the minimum thickness of the disc, even at one
point, is less than the prescribed limit, replace the
disc.
Minimum thickness of the brake disc: 3.5 mm (0.137
in)
With a dial gauge, check that the disc oscillation does
not exceed the allowed tolerance. Replace if neces-
sary.
Brake disc oscillation tolerance: 0.1 mm (0.004 in)
CAUTION

GENERAL INFORMATION).
Take down the front wheel (REMOVING THE FRONT
WHEEL).

NOTE Turn in all screws manually, and then tighten
them diagonally in the following order: A-B-C-D-E.
Check the disc direction of rotation.
When refitting, apply LOCTITE ® 270 over the
threads of the brake disc screws.
