Inspection Procedure

Rotor run-out is easily measured using a dial indicator which is firmly attached to a front suspension component. Thickness variation measurements require careful use of an accurate micrometer as the service limit is very small (0.01 mm, 0.0004 in). Refer to Figure 1 and 2.



CONTACT SURFACE

Check rotor for roughness, cracks or chips.


RUNOUT

Check runout using a dial indicator. Make sure that axial end play is within specification. Refer to FA section.

Rotor repair limit:
Maximum runout (Total indicator reading at center of rotor pad contact surface) 0.07 mm (0.0028 in)


Measure the run-out on the inside and outside of the rotor at the center of the rotor/pad contact surface.

THICKNESS Minimum thickness:
OPZ25V non-turbo 24.0 mm (0.945 in) OPZ25VA turbo 28.0 mm (1.102 in)


Measure the thickness in at least eight (8) even locations around the rotor.
