Thickness and Parallelism

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.

19-33

10 mm (0.39 in.)

1. Raise the rear of the vehicle, and support it with

safety stands in the proper locations (see page
1-11).

2. Remove the rear wheels.

3. Remove the brake pads (see page 19-29).

4. Using a micrometer, measure the brake disc

thickness at eight points, about 45 ° 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.

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

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

parallelism, refinish the brake disc with a Honda-
approved 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 19-29).

7. Clean the mating surfaces between the brake disc

and the inside of the wheel, then install the rear
wheels.

NOTE: Keep any grease off the brake disc and brake
pads.

1. Raise the rear of the vehicle, and support it with

safety stands in the proper locations (see page
1-11).

2. Remove the rear wheel.

3. Release the parking brake lever fully.

4. Remove the brake hose mounting bolt (A) from the

bracket.

5. Remove the brake caliper bracket mounting bolts

(B), then remove the caliper assembly (C) from the
knuckle. To prevent damage to the caliper
assembly or brake hose, use a short piece of wire
to hang the caliper assembly from the
undercarriage. Do not twist the brake hose and the
parking brake cable excessively.

NOTE: Make sure the washers (D) position on
reassembly, if they are removed (see step 5 on
page 18-32).

6. Remove the brake disc flathead screws (A).

7. Remove the brake disc (B) from the hub bearing

unit.

NOTE: If the brake disc is stuck to the hub bearing
unit, thread two 8 x 1.25 mm bolts (C) into the brake
disc to push it away from the hub bearing unit.
Turn each bolt 90 degrees at a time to prevent the
brake disc from binding.

8. Install the brake disc in the reverse order of

removal, and note these items:

• Before installing the brake disc, clean the mating

surfaces between the hub bearing unit and the
inside of the brake disc.

• Adjust the parking brake (see page 19-8).

9. Inspect the brake disc runout (see page 19-32).

10. Clean the mating surfaces between the brake disc

and the inside of the wheel, then install the rear
wheel.

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.

• Avoid breathing dust particles.
• Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:

NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin B and lower caliper pin A are different.
If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid pad wear, and possibly
uneven tire wear.

• Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off

immediately with water.

• To prevent dripping brake fluid, cover disconnected hose joints with rags or shop towels.
• Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
• Before reassembling, check that all parts are free of dirt and other foreign particles.
• Replace parts with new ones as specified in the illustration.
• Make sure no dirt or other foreign matter gets into the brake fluid.
• Make sure no grease or oil gets on the brake discs or pads.
• When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
• Do not reuse drained brake fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container. Using a

non-Honda brake fluid can cause corrosion and shorten the life of the system.

• Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
• Use recommended greases in the rear caliper set.
• After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
