INNER PAD
OUTER PAD
lnstall the brake pads and pad shims correctly.
Install the pad with the wear indicator on the inside.
. When reusing the pads, always reinstall thebrake pads in their original positions to prevent
loss of braking efficiency.. Contaminated brake discs or pads reduce stop-ping ability. Keep grease off the discs and pads.

Pivot the caliper down into position, being careful
not to damage the pin boot. Install the caliper bolt
and tighten it,
Press the brake pedal several times to make sure
the brakes work, then test-drive.
NOTE: Engagement of the brake may require agreater pedal stroke immediately after the brakepads have been replaced as a set. Several applica-
tions of the brake pedal will restore the normalpedal stroke.
After installation, check for leaks at hose and linejoints and connections, and retighten if necessary.

Front Brake Disc
Disc Runout Inspection
l.Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the brake pads {see page 19-9).
Inspect the disc surface for damage and cracks.
Clean the disc thoroughly, and remove all .ust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and maasure the runout at
10 mm (0.4 in) from the outer edge of the disc.
Brake Di3c Runout:
Service Limit: 0.10 mm {0.00,0 in)
WHEEL NUT ANDPLAIN WASHER108 N.m {11 kg{ m, 80 lbf.ft)
lf the disc is beyond the service limit, refinish the
brake disc with an on-car brake lathe. The Kwik-
Lathe produced by Kwik-way Manufacturing Co.
and the "Front Brake Disc Lathe" offered by Snap-
on Tools Co. are approved for this operation.

NOTE: A new disc should bs refinished if its runout
is greater than 0.10 mm (0.004 in).
Disc Thickness and Parallelism
Inspection
1.Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the brake pads (see page 19-9).
Using a micromater, measure disc thickness at eight
points, approximately 45'apan and 10 mm (0.4 in)
in from the outer edge of the disc. Replace the brake
disc if the smallest measurement is less than the
max. refinishing limit.
Brake Disc Thickness:
Standard:'97 - 98 modsls:
22.9 -23.1mm {0.90 - 0.91 inl'99 - 00 mod€ls:
23.6 - 23.8 mm {0.93 - 0.94 in}
Max. Refinishing Limit:21.0 mm (o.txl in)
Brake Disc Parallelism: 0.015 mm {0.0006 in} max.
NOTE: This is the maximum allowable difference
between the thickness measurements,
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
The Kwik-Lathe produced by Kwik-Way Manufac-
turing Co. and the "Front Brake Disc Lathe" offered

Front Brake Caliper
Disassembly/Reassembly
. Never use an air hose or dry brush to clean brake assemblies.
. Use an OSHA approved vacuum cleaner to avoid breathing brake dust.
. Contaminated brake discs or pads reduce stopping ability.
. When reusing the pads, always reinstallthe brake pads in their original positions to prevent loss ol braking efficiency.
CAUTION:
. Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off imme-
diatelY with water.
NOTEI
. To prevent spills, cover the hose joints with rags or shop towels.
. Clean all pans in brake fluid and air dry; blow out all passages with compressed air.
. Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.
. Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
. Do not reuse the drained fluid.
. Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the
life of the system.
. Coat the piston, piston seal, and caliper bore with clean brake fluid.
. ReDlace all rubber oarts with new ones whenever disassembled.
. After installing the front brake caliper do the following.- Check for leaks at hose and line joints and connections, and retighten if necessary.- Check the brake hoses for interference and twistinq.

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.

Brake Hoses/Lines
Inspection/Torque Specif ications
1. Inspect the brake hoses for damage, deterioration, leaks, interference, and twisting
2. Check the brake Iines for damage, rusting, and leakage. Also check for bent brake lines.
3. Check for leaks at hose and line joints and connections, and retighten if necessary.
4. Checkthe master cylinder, proportioning control valve. and ABS modulator unit for damage and leakage.
NOTE: Replace the brake hose clip whenever the brake hose is serviced.

ABS Control
The ABS control unit detects the wheel speed based on the wheel sensor signal it received, then it calculates the vehicle
speed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration based on the
rate of deceleration.
The ABS control unit calculates the slip rate of each wheel, and it transmits the control signal to the modulator unit
solenoid valve when the slip rate is high
The pressure reduction control has three modes: pressure reducing, pressure retaining, and pressure intensi{ying modes.
Self-diagnosis Function
The ABS control unit is equipped with a main cPU and a sub cPU, that check each other for problems.
The CPUs check the circuit of the system.
When the CPUS detect failure, they shift to the "system down mode" or the "control inhibition mode".
The self-diagnosis can be classitied into these four categories:
O: Initial diagnosis
O: Except ABS control
O; During ABS control
@: During warning
On-board Diagnosis Function
The ABS system can be diagnosed with the Honda PGM Tester.
The ALB Checker cannot be used with this system. For air bleeding. and checking wheel sensor signals, use the Honda
PGIM Tester. See the Honda PGM Tester user's manuals for specific operating instructions.
