Rear Brake Disc Inspection
Rear Brake Disc Inspection
Thickness and Parallelism
1. Raise and support the vehicle .
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 max. refinishing limit.
NOTE: 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. Install the brake pads.
Runout
1. Raise and support the vehicle .
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.
Brake disc/drum runout:
Service limit: 0.04 mm (0.0016 in)
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.
Max. refinishing limit:9.0 mm (0.354 in)
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 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.
