Master Cylinder/Brake Booster
Removal/lnstallation
1, Disconnect the brake fluid level switch connectors.
2. Remove the reservoir cap from the master cylinder.
3. Remove the brake fluid from the master cvlinder
reservoir with a syringe.
4. Disconnect the brake lines from the master cylinder.
To prevent spills, cover the line joints with rags or
shop towels.
5. Remove the master cylinder mounting nuts and
wasners.
6. Remove the master cylinder from the brake booster.
CAUTION: Be careful not to bend or damage the
brake lines when removing the master cylinder.
Do not spill brake fluid on the vehicle; it may dam.
age the paint; it brake fluid does cont.ct the paint,
wash it oft immediately with water.
7. Disconnect the vacuum hose from the brake booster.
8. Remove the cotter pin and clevis pin from the clevis.
Do not disconnect the clevis by removing it from
the operating rod of the brake booster. lf the clevis
is loosened, adjust the pushrod length before
installing the brake booster (see page 19-15).

9. Remove the four booster mounting nuts.'10. Pull the brake booster forward until the clevis is
clear of the bulkhead.
11. Remove the brake booster from the enqine com-
panment.
12. Install the brake booster and master cylinder in the
reverse order of removal, and note these items:
. When connecting the brake lines, make sure that
there is no interference between the brake lines
and other parts.
. Be careful not to bend or damage the brake lines
when installing the master cylinder.
. lf replacing the master cylinder or brake booster,
check and adjust the pushrod clearance before
installing the master cylinder (see page 19-14).
Fill the master cylinder reservoir, and bleed the
brake system (see page 19-7).
After installation, check the brake pedal height and
brake pedal free play (see page 19-5), and adjust if
necessary.

Pushrod Clearance Adjustment
NOTE: Master cylinder pushrod-to-piston clearance must
be checked and adjustments made, if necessary. before
installing the master cylinder.
1. Set the special tool on the master cylinder body;
push in the center shaft until the top ot it contacts
the end of the secondary piston by turning the ad-justing nut.

ADJUSTING NUT
Without disturbing the center shaft's position, in-

Install the master cylinder nuts, and tighten them to
the sDecified toroue.
Connect the booster iniine with a vacuum gauge 0 -
101 kPa (0 - 760 mmHg, 30 in Hg) to the booster's
engine vacuum supply, and maintain an engine
speed that will deliver 66 kPa (500 mmH9, 20 in Hg)
vacuum.
With a feeler gauge, measure the clearance between
the gauge body and the adiusting nut as shown.

lf the clearance between the gauge body and
adjusting nut is 0.4 mm (0.02 in), the pushrod-to-
piston clearance is 0 mm. However. if the clearance
between the gauge body and adjusting nut is 0 mm,
the pushrod-to-piston clearance is 0.4 mm (0.02 in)
or more. Therefore it must be adjusted and
recheck€d.
lf clearance is incorrect, loosen the star locknut, and
turn the adjuster in or out to adjust.
. Adjust the clearance while the specified vacuum
is applied to the booster.
. Hold the clevis while adjusting.
Tighten the star locknut securely.

Brake Booster Inspection
FunctionalTest
1. With the engine stopped, press the brake pedal sev-
eral times to deplete the vacuum reservoir. thenpress the pedal hard, and hold it for 15 seconds. lf
the pedal sinks, either the master cylinder is
bypassing internally, or the brake system (master
cylinder, lines, modulator, proportioning valve. or
caliper) is leaking.
2. Start the engine with the pedal pressed. lf the pedal
sinks slightly. the vacuum booster is operating nor-
mally. lf the pedal height does not vary, the booster
or check valve is faultv.
3. With the engine running, press the brake pedal light-
ly. Apply just enough pressure to hold back auto-
matic transmission creep. lf the brake pedal sinks
more than 10 mm (3/8 in.) in three minutes, the mas-
ter cylinder is faulty. A slight change in pedal height
when the Ay'C compressor cycles on and off is nor-
mal. (The Ay'C compressor load changes the vacuum
available to the booster.)
Leak Test
1.Press the brake pedal with the engine running, then
stop the engine. lf the pedal height does not vary
while pressed for 30 seconds, the vacuum booster is
OK. lf the pedal rises, the booster is faulty.
With the engine stopped, press the brake pedal sev-
eral times using normal pressure. When the pedal is
first pressed. it should be low, On consecutive appli-
cations, the pedal height should gradually rise. lf thepedal position does not vary. check the booster
check valve.
Boostor Chock Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Start the engine, and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve. and retest.

Kickback'1. The motor operates when the ABS is functioning. and the fluid in the reservoir is forced out to the master cylinder,
causing kickback at the brake pedal.
2. The ABS control unit operates the solenoid valve when the brake pedal is released after the initial diagnosis You may
hear the solenoid valve operate at this time, but it is normal
Pumo Motol
1. The pump motor operates when the ABS is functioning
2. The ABS control unit checks the pump motor operation during acceleration. You may hear the motor operate at this
time, but it is normal.
Brake Fluid Replacement/Ail Bleeding
L Brake fluid replacement and air bleeding procedures are the same as for vehicles without ABS To ease bleeding, start
with the front wheels.
Troubleshooting
1. The troubleshooting flowchart procedures assume that the cause of the problem is still present and the ABS indicator
is still on. Following the flowchart when the ABS indicator does not come on can result in incorrect diagnosis.
2. Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
Self-diagnosis is made at various times such as the initial diagnosis, except ABS control, during ABS control, during
acceleration, during the specified vehicle speed, etc. Therefore, the symptom canngt be checked unless the check
conditions match with the problem conditjons
3. When the ABS jndicator does not come on during the test-drive. but troubleshooting is performed based on the DTC,
check lor loose connectors, poor contact of the terminals, etc., before you start troubleshooting.
4. After troubleshooting, erase the DTC and test-drive the vehicle. Be sure the ABS indicator does not come on.
5. The connector illustratjons show the female terminals with a single outline and the male terminals with a double out-
l ne.
ABS Function Test
To simulate ABS operation and activate the solenoid valves and pump, use the Honda PGM Tester.
Connect the PGM Tester to the 16P Data Link Connector (DLC). When the System Select menu is displayed, select the ABS
Test Mode menu, and follow the tester's prompts.
