Runout

1. Raise and support the vehicle (see page 1-13).

2. Remove the rear wheels.

3. Remove the brake pads (see page 19-31), 4. Inspect the brake disc to wheel surface for damage and cracks. Clean the brake disc thoroughly, and remove all rust.

5. Install suitable flat washers (A) and the wheel nuts (B), and tighten the wheel nuts to the specified torque to hold the brake disc securely against the hub.

6. Set up the dial gauge against the brake disc as shown,


6. Set up the dial gauge against the brake disc as shown, and measure the runout at 10 mm (0.39 in) from the outer edge of the brake disc.

Brake disc runout:

Service limit: 0.04 mm (0.0016 in)

7. If the brake disc is beyond the service limit, refinish the brake disc with a Honda-approved commercially available on-car brake lathe.

Max. refinishing limit: 8.0 mm (0.31 in)

NOTE: - If the brake disc is beyond the service limit for refinishing, replace it (see page 19-34).

- If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is out of specification, refinish the disc.

8. Install the brake pads (see page 19-31).

9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear wheels.

Thickness and Parallelism

1. Raise and support the vehicle (see page 1-13).

2. Remove the rear wheels.

3. Remove the brake pads (see page 19-31).

4. Using a micrometer, measure the brake disc thickness at eight points, about 45 В° apart and 10 mm (0.39 in) in from the outer edge of the brake 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 (0.35-0.36 in)

Max. refinishing limit: 8.0 mm (0.31 in)

Brake disc parallelism:

0.015 mm (0.0006 in) max.

NOTE: This is the maximum allowable difference between the thickness measurements.

5. If the brake disc is beyond the service limit for


5. If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a Hondaapproved commercially available on-car brake lathe.

NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see page 19-34).

6. Install the brake pads (see page 19-31).

7. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear wheels.
