CHECKING THE BRAKE DISC
This check must be done with the brake disc
installed on the wheel.
Make a visual check of the brake disc surface. If there
are any lines or signs of wear, replace the disc, see
(REMOVING THE BRAKE DISC).
Check the brake disc for wear by measuring the
minimum thickness in different points using a mi-
crometer. If the minimum thickness is less than the
limit value, even in a single point, replace the disc.
Minimum brake disc thickness value: 0.137 in (3.5 mm)
Use a dial indicator to check that disc oscillation does
not exceed tolerance levels and if it does, replace the
disc.
Brake disc oscillation tolerance: 0.004 in (0.1 mm)
CAUTION

®

disc screw threads.
