racK.
20. lnsert a 24" long,3/8" drive extension and the spe-
cial tool into the cvlinder from the left side. Make
sure that the special tool is securely positioned on
the backup ring edges. Be careful not damage to

21.Set the gearbox in a press, then press out the cylin-
der end seal and backup ring from the gearbox.
Note these items when pressing the cylinder end
seat:
. Keep the tool straight to avoid damaging the
cylinder wall. Check the tool angle, and correct it if
necessary, when removing the cylinder end seal.
. Use a press to remove the cylinder end seal. Do
not try to remove the seal by striking the tool. lt
will break the backup ring, and the cylinder end
sealwill remain in the gearbox.

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.

Bleeding
CAUNON:
. Do not spill brake tluid on the vehicle. it may damage
the paint; if brake fluid does contaqt th€ paint, wash
it otf immodiately with water.
. Maks sure no dirt oy other forsign matter is allowsd
to contaminate the brake fluid.
NOTE:
. 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 svstem.
. The reservoir on the master cylinder must be at the
MAX (upper) level mark at the start of bleeding pro-
cedure and checked after bleeding each brake caliper
and wheel cylinder. Add fluid as required.
1, Make sure the brake fluid level in the reservoir is at
the MAX (uDDer) level line.

Have someone slowly pump the brake pedal several
times, then apply steady pressu.e.
Loosen the brake bleed screw to allow air to escape
from the system. Then tighten the bleed screw
securely.
Repeat the procedure for each wheel in the sequence
shown below until air bubbles no longer appear in
the tluid.
Refill the reservoir on the master cvlinder to the

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.

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.

Anti-lock Brake System (ABS)
Features/Gonstruction (cont'd)
ABS Modulator
The ABS modulator consists of the inlet solenoid valve, outlet solenoid valve, reservoir, pump, pump motor and thedampjng chamber.
The modulator reduces the caliper fluid pressure directly. lt is a circulating-type modulator because the brake fluid circulatesthrough the caliper, reservoir and the master cylinder.The hydraulic control has three modes: pressure reduction, pressure retaining and pressure intensifying modes.The hydraulic circuit is the independent four channel-type, one channel for each wheel.
SOLENOID VALVE
t-
Pressure intensifying mode: Inlet valve open, outlet valve closed,
Pressure retaining mode:
Pressure reduction mode:
Motor operation mode:
Master cylinder fluid is pumped out to the caliper.Inlet valve closed, outlet valve closed.
Caliper fluid is retained by the inlet valve and outlet valve.Inlet valve closed, outlet valve ooen
Caliper fluid flows through the outlet valve to the reservoir.When starting the pressure reduction mode. the pump motor is ON.When stopping ABS operation, the pump motor is OFF.The reservoir fluid is pumped out by the pump, through the damping chamber, to the mastercylinder.
