Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle, and make sure it is
securely supported.
2. Remove the brake pads (see page 19-19).
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
disc.
Brake Disc Runout:
Service Limit: 0.10 m m (0.004 in.)
B
A
5. If the disc is beyond the service limit, refinish the
brake disc.
Max. Refinishing Limit: 8.0 mm (0.31 in.)
NOTE: A new disc should be refinished if its runout
is greater than 0.10 mm (0.004 in.).
Thickness and Parallelism
1. Loosen the rear wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the rear wheels.
2. Remove the brake pads (see page 19-19).
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
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.) max.
This is the maximum allowable difference between
the thickness measurements.
4. If the disc is beyond the service limit for parallelism,
refinish the brake disc.
NOTE: If the brake disc is beyond the service limit
for refinishing, replace it (see page 18-22).
