NOTE: If both the ABS indicator and the brake system
indicator come on at the same time, check the ABS or
VSA system for DTC’s first: ABS (see page 19-49), VSA
(see page 19-97).
1. Remove the center console (see page 20-92).
2. Disconnect the parking brake switch connector (A) from the parking brake switch (B).
3. Check for continuity between the switch terminal (C) and body ground.
 With the parking brake lever pulled, there s hould
be continuity.
 With the parking brake lever released, there should be no continuity.
NOTE: If the parking brake switch and fluid level
switch are OK, but the brake system indicator does
not function, do the gauge control module self-
diagnostic function (see page 22- 241).
4. Reconnect the parking brake switch connector.
5. Reinstall the center console (see page 20-92). 1. Disconnect the brake fluid level switch connector.
2. Check for continuity between the terminals (1) and
(2) with the float in the down position and in the up
position.
NOTE: Remove the brake fluid completely from the reservoir. With the float down, there should be
continuity.
 Fill the reservoir with brake fluid to the MAX (upper) level (A). With the float up, there should
be no continuity.
 If both the ABS indicator and the brake system indicator come on at the same time, check the
ABS or VSA system for DTC’s first: ABS
(see page 19-49), VSA (see page 19-97).
 If the parking brake switch and fluid level switch are OK, but brake system indicator does not
function, do the gauge control module self-
diagnostic function (see page 22-241).
3. Reconnect the brake fluid l evel switch connector.

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.
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. Check the thickness (A) of the inner pad (B) and the outer pad (C). Do not include the thickness of the
backing plate.
4. If any part of the brake pad thickness is less than the service limit, replace the rear brake pads as a
set.
5. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels. 1. Remove some brake fluid from the master cylinder.
2. Raise the rear of the vehicle, and support it with
safety stands in the proper locations (see page
1-11).
3. Remove the rear wheels.
4. Remove the brake hose mounting bolt (A).
5. Remove the flange bolts (B) while holding respective caliper pin (C) with a wrench. Be careful
not to damage the pin boot, and remove the caliper
(D). Check the hose and pin boots for damage and
deterioration.
NOTE: Do not twist the brake hose and the parking
brake cable to prevent damage.

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 disc onnected 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.
