Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle, and support it with
safety stands in the proper location (see page 1-8),
Remove the rear wheels.
2. Remove the brake pads (see page t9-20).
3. Inspectthe disc surface for damage and cracks.
Clean the disc thoroughly, and remove all rust.
4. Install suitable flatwashers (A) and wheel nuts, and
tighten the nuts to the specified torque to hold the
brake disc securely against the hub.
5. Set up the dial ga uge against the brake disc as
shown, and measure the runout at 10 mm (0,4 in.)
from the outer edge of the disc.
Brake Disc Runout:
Service Limit: 0.10 mm (0.004 in.)
6. lf the disc is beyond the service limit, refinish the
brake disc.
Max. Refinish Limit: 8.0 mm (0.31 in.)
NOTE:
. lf the brake disc is beyond the service limitfor
refinishing, replace it (see page 18-24).
. A new disc should be refinished if its runout is
g r e a t e r t h a n 0 . 1 0 m m ( 0 . 0 0 4 i n . ) .

Thickness and Parallelism
1. Raise the rear of the vehicle, and support it with
safety stands in the proper location (see page 1-8).
Remove the rear wheels.
2. Remove the brake pads (see page 19-20).
3. 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.
Brake Disc Thickness:
Standard: 8.9-9.1 mm {0.350 0.358 in.)
Max. Refinishing Limit: 8.0 mm (0.31 in.)
Brake Disc Parallelism: 0.015 mm (0.0006 in.l
max.
NOTE: This is the maximum allowable difference
between the thickness measurements.
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
NOTE: lf the brake disc is beyond the service limit
for refinishing, replace it {see page 18-24).
