Loosen the front wheel nuts slightly, then raise the
vehicle and suppon it on safety stands. Remove the
front wheels.
Remove the brake pads (see page 19-8).
Inspect the disc surface for damage or cracks. Clean
the disc thoroughly and remove all rust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and measure the runout aat 10
mm (0.4 in) from the outer edge of the disc.

. When the vehicle is equipped with a limited slip
differential, raise both front wheels off the
ground.

Remove the brake pads (see page 19-8).
Using a micrometer, measure disc thickness at
eight points, approximately 45'apart and 10 mm
(0.4 in) in from the outer edge of the disc. Replace
the brake disc if the smallest measurement is less
than the max. refinishing limit.

Disc Thickness and Parallelism
Loosen the rear wheel lug nuts slightly, then raise
the vehicle and support it on safety stands. Remove
the rear wheels.
Remove the brake pads (see page 19-16).
Using a micrometer, measure disc thickness at
eight points, approximately 45" apart and 10 mm
(0.4 in) in from the outer edge of the disc. Replace
the brake disc if the smallest measurement is less
