Disc Inspection
•
The following operations must be car-
ried out with the brake discs fitted on
the wheel; they refer to a single disc,
but are valid for both.
•
Check the disc for wear by measuring
the minimum thickness with a micro-
meter in different points. If the mini-
mum thickness, even in a single point
of the disc, is less than the minimum
value, replace the disc.
Disc thickness minimum value: 4 mm (0.16 in)
•
Using a dial gauge, check that the max-
imum oscillation of the disc does not
exceed the tolerance; otherwise, re-
place it.
