Mount Dial Indicator, Special Tool C-3339, and
Mounting Adaptor, Special Tool SP-1910, to the steer-
ing knuckle. Position the indicator stem so it contacts
the hub face near the outer diameter. Care must be
taken to position stem outside of the stud circle, but
inside of the chamfer on the hub rim (Fig. 101).

Hub runout should not exceed 0.08 mm (0.003
inch). If runout exceeds this specification, the hub
must be replaced. For front hub removal, (Refer to 2
- SUSPENSION/FRONT/KNUCKLE - REMOVAL).
For rear hub removal, (Refer to 2 - SUSPENSION/
REAR/HUB / BEARING - REMOVAL).
If the hub runout does not exceed this specifica-
tion, install the rotor back on the hub, aligning the
chalk marks on the rotor with a wheel mounting
stud, two studs apart from the original stud (Fig.
102). Tighten nuts in the proper sequence and torque
to specifications.

Recheck brake rotor runout to see if the runout is
now within specifications. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTOR
TIONS)
If runout is not within specifications, reface or
replace the brake rotor. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTOR
PROCEDURE)
STANDARD PROCEDURE - BRAKE ROTOR
MACHINING
NOTE: Refacing the rotor is not required each time
the brake pads are replaced, only when the need is
foreseen.
Any servicing of the rotor requires extreme care to
maintain the rotor within service tolerances to
ensure proper brake action.
