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.

Front Brake Pads
Inspection and Replacement
1.
Nsvgr u9e an air hose or dry brush to clean brake
assemblies.
Use an OSHA approved vacuum cleaner to avoid
broathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the caliper bolt, and pivot the caliper up
out of the way. Check the hoses and pin boots for
damage and deterioration.

4. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickness:
Standard: 10.5 - 11.5 mm {0.,11 - 0.45 in)
Servics Limit: 1.6 mm (0.06 in)
lf the brake pad thickness is less than the service
limit. replace the front pads and shims together as a
set.
Clean the caliper thoroughly; remove any rust, and
check for grooves and cracks.
Check the brake disc for damage and cracks.
Install the pad retainers.

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.

Charging
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid breathing th€ air conditioner refrigerant
and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service. Additional health and
safety information may be obtained from the relrigerant
and lubricant manufacturers.
Connect a R-'134a refrigerant recovery/recycling/charging
station to the vehicle, as shown. following the equipment
manufacturer's instructions.
R€covery/Recycling/Charging Station
HIGH-PRESSURESIDE
Add the same amount of new refrigerant oil to system
that was removed during recovery. Use only SP-'10
refrigerant oil.
Charge the system with Required amount of R-134a
refrigerant. Do not overcharge the system; the compres-
sor will be damaged.
Select the appropriate unit of measure for your
charging station.
Refrigerant capacity: 700 to 750 g

Leak Test
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditionor refrigerant and
lubricant vapor or mist can irritate eyes, nose and throat.
Avoid breathing the air conditioner retrigerant and lubri-
cant vapor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle ajr conditioner sys-
tems should not be pressure tested or leak tested with
compressed arr.
!@ some mixturos of air and R-1348 have
been shown to be combustible at olovatod pres3uras
and can result in fire or explosion causing iniury or
property damage. Never use comprelised air to pressure
test R-13ila service equipment or vehicle air conditioner
systems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.

1.Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
Open the high-pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.
Select the appropriate unit of measure for your
charging station.
Refrigerant capacity: 700 to 750 g
0.70 to 0.75 kg
1.5 to 1.6 lbs.
21.7 to 26.5 oz.
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 ozl
per year or better.
lf you find leaks that require the system to be opened
(to repair or replace hoses, fittings, etc.), recover the
system according to the Recovery Procedure on page
22-59.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-601.
