Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle. and support it with
safety stands in the proper locations (see page
1 - 1 3 ) .
2. Remove the brake pads (see page 19-20).
3. Inspect the disc surface for damage and cracks.
Clean the disc thoroughly. and remove all rust
4. Use wheel nuts and suitable flat washers (A)to
hold the disc securely against the hub, then mount
a dial indicator (B) as shown, and measure the
runout at 10 mm (0.4 in.) from the outer edge of the
d i s c .
Brake Disc Runout:
Service Limit: 0.10 mm {0.004 in.)
lf the disc is beyond the service limit, refinish the
brake disc. Do not use an engine-driven on-car
brake lathe. Use only a motor-driven on-car brake
lathe.
Max. Rofinishing Limii:
10.0 mm (0.39 in.)
NOTE: A new disc should be refinished if its runout
i s 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. Loosen the rear wheel nuts slightly, then raisethe
vehicle, and support it with safety stands in the
proper locations (see page 1-13). Remove the rear
w n e e r s .
2. Remove the brake pads (see page 19-20).
3. Using a micrometer (A), 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
t h a n t h e m a x . r e f i n i s h i n g l i m i t .
Brake Disc Thickness:
Standard: 11.9-12.1 mm (0.469-0.476 in.l
Max. Refinishing Limit:
10.0 mm (0.39 in.)
Brake Disc Parallelism: 0.015 mm
(0.0006 in.) max.
This is the maximum allowable difference between
the thickness measurements.
lf the disc is beyond the service limit for parallelism,
refinish the brake disc. Do not use an engine-driven
on-car brake lathe. Use only a motor-driven on-car
brake lathe.
NOTE: lf the brake disc is beyond the service limit
for refinishing, replace it (see step 7 on page 18-30).
