Rear Brake Disc Inspection




Rear Brake Disc Inspection

Thickness and Parallelism

1. Raise and support the vehicle Service and Repair.

2. Remove the rear wheels.

3. Remove the brake pads.

4. Using a micrometer (A), measure the brake disc/drum thickness at eight points, about 45° apart and 10 mm(0.39 in) in from the outer edge of the brake disc/drum. Replace the brake disc/drum if the smallest measurement is less than the maximum refinishing limit.





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





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

NOTE: If the brake disc/drum is beyond the service limit for refinishing, replace it Rear Brake Disc Replacement.

6. Inspect the brake disc/drum runout.

Runout

1. Raise and support the vehicle Service and Repair.

2. Remove the rear wheels.

3. Remove the brake pads.

4. Inspect the brake disc/drum to wheel surface for damage and cracks. Clean the brake disc/drum thoroughly, and remove all rust.

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





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





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





NOTE:

- If the brake disc/drum is beyond the service limit for refinishing, replace it Rear Brake Disc Replacement.
- If the brake disc/drum is replaced with a new one, check the new disc/drum for runout. If the new disc/drum is out of specification, refinish the disc/drum.

8. Install the brake pads.

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