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. 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 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, and measure the runout at 10 mm (0.39 in.)
from the outer edge of the brake disc. 7. If the brake disc is beyond the service limit, 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).
 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 19-29).
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels.

Installation
19-91
1. Install the ABS modulator-control unit onto the brackets.
2. Install the bracket with the ABS modulator-control unit to the body.
3. Reconnect the six brake lines, then tighten the flare nuts to the specified torque.
4. Align the connecting surface of the ABS modulator-control unit 25P connector to the ABS modulator-control unit.
5. Lower the lock of the ABS modulator-control unit 25P connector, then confirm the connector is fully seated.
6. Bleed the brake system (see page 19-9).
7. Start the engine, and make sure the ABS indicator goes off.
8. Test-drive the vehicle, and make sure the ABS indicator does not come on.NOTE: If the brake pedal is spongy, there may be air trapped in the modulator which could then be induced into
the normal brake system during modulation. Bleed the brake system again (see page 19-9).

4. Apply multi-purpose grease to the wheel speedsensor O-ring (A) and the sensor hole in the knuckle
(B).
5. Insert the guide pin tool (A) into the wheel speed sensor bolt hole until the shoulder of the tool
contacts the wheel speed sensor bracket.
NOTE: To prevent O-ring damage, the wheel speed
sensor must be installed with the guide pin tool. 6. Insert the wheel speed sensor (A) and the guide pin
tool (B) into the bolt hole on the knuckle.
NOTE: To ensure proper alignment when pushing
the wheel speed sensor into the knuckle housing,
do not hold the sensor bracket during installation,
hold the sensor wire.
7. Gently push and pull the wheel speed sensor in and out to make sure the O-ring is sliding properly in its
housing. While you are doing this, make sure the
sensor doesn’t come out of the knuckle assembly. If
the sliding effort is too high, remove the wheel
speed sensor, inspect the O-ring for damage, and
start the installation process again.
8. Remove the guide pin tool, then install the bolt, and tighten it to specified torque.
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheel.
10. Start the engine, and make sure the ABS indicators go off.
11. Test-drive the vehicle, and make sure the ABS indicators do not come on.

This system is composed of the VSA modulator-control unit, the wheel speed sensors, the steering angle sensor, the
yaw rate-lateral acceleration sensor, and the system indicators in the gauge control module (tach). The VSA
modulator-control unit controls the ABS, EBD, TCS, VSA, and brake assist with the brake pressure of each wheel and
reduces engine torque.

The electronic brake distribution (EBD) feature helps control vehicle braking by adjusting the rear brake force in
accordance with the rear wheel load before the ABS operates. Based on the wheel speed sensor signals, the control
unit uses the modulator to control the rear brakes individually. When the rear wheel speed is less than the front wheel
speed, the VSA modulator-control unit retains the current rear brake fluid pressure by closing the inlet valve in the
modulator. As the rear wheel speed increases, and approaches the front wheel speed, the VSA modulator-control unit
increases the rear brake fluid pressure by momentarily opening the inlet valve. This whole process is repeated very
rapidly. While this is happening, kickback may be felt at the brake pedal.
When a drive wheel loses traction on a slippery road surface and starts to spin, the VSA modulator-control unit applies
brake pressure to the spinning wheel, and sends an engine torque control request to the ECM/PCM to slow the
spinning wheel and keep traction.

NOTE: Do not damage or drop the combination switch as the steering angle sensor is sensitive to shock and vibration.
1. With the wheels in the straight-ahead position and the steering wheel centered, remove the steering wheel (see page 17-6).
2. Remove the steering column covers (see page 17-9) and the cable reel (see page 24-200).
3. Remove the combination switch assembly (see step 11 on page 17-11).
4. Remove the combination light switch (A) and the wiper/washer switch (B) from the combination switch body assembly (C).
5. Install the combination switch body assembly in the r everse order of removal.
NOTE:  Do not remove the steering angle sensor from the combination switch body.
 When installing the cable reel, set the turn signal canceling sleeve position so that the arrow points straight up (see page 24-201).
 When installing the combination switch, tighten the m ounting screws to the specified torque and sequence
shown (see page 17-12).
