NOTE: Only reinstall the original 32 mm shim(s)
when the steering gearbox is reassembled without
replacing the pinion shaft. valve housing, and gear-
box housing with new ones.
lf the pinion shaft, valve housing, and gearbox
housing are replaced, select the new shim{s) as fol-
lows.
Shim selection:
Set the four 32 mm shims on the bearing surface of the
gearbox housing. Total thickness of the four shims
should equal no more than 0.70 mm.
Shim set: four 32 mm shims (Thickness: 0.10 mm, 0.15
mm, 0.20 mm, 0.25 mm respectively)
NOTE: The four 32 mm shims do not have thickness
identification marks. Measure the thickness of each shim
using a micrometer, and mark the shim for identification.

Inspection and Adjustment
Brake System Rubber Parts and Brake Booster
@-Brake Booster
Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster. Replace the brake booster as an assembly ifit does not work properly or if there are signs of leak-
age.
@-Piston Cup and Pressure Cup Inspection. Check brake operation by applying the brakes.
Visually check for damage or signs of tluid leakage.Replace the master cylinder as an assembly if thepedal does not work properly or if there is damage orsigns of fluid leakage.
. Check for a difference in brake pedal stroke betweenquick and slow brake applications. Replace the mas-.
ter cylinder if there is a difference in pedal stroke.
(9-Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is dam-
aged or leaking.
O-Caliper Piston S€al and Piston Boots
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage. lf
the pedal does not operate properly, the brakes drag,
or there is damage or signs of fluid leakage, disas-
semble and inspect the brake caliper. Replace the
boots and seals with new ones whenever the brake
caliper is disassembled.
@-Wheel Cylinder Piston Cup and Dust Cover
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage. lf
the pedal does not operate properly, the brakes drag,
or there is damage or signs of fluid leakage, replace
the wheel cvlinder.

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.

'11. Push in the piston so that the caliper willfit over thepads. Make sure the piston boot is in position toprevent damaging it when pivoting the caliper
down.

13.
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 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.

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.

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.
