Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
 Avoid breathing dust particles.
 Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.
Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:
NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin B and lower caliper pin A are different.
If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid pad wear, and possibly
uneven tire wear.  Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
 To prevent dripping brake fluid, cover disc onnected hose joints with rags or shop towels.
 Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
 Before reassembling, check that all parts are free of dirt and other foreign particles.
 Replace parts with new ones as specified in the illustration.
 Make sure no dirt or other foreign matter gets into the brake fluid.
 Make sure no grease or oil gets on the brake discs or pads.
 When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
 Do not reuse drained brake fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
 Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
 Use recommended greases in the rear caliper set.
 After installing the caliper, check the brake hose and line for leaks, interference, and twisting.

A/C Service Tips and Precautions A/C System Inspection
A
 Compressed air mixed with the R-134a forms a
combustible vapor.
 The vapor can burn or explode causing serious injury.
 Never use compressed air to pressure test R-134a service equipment or vehicle air
conditioning systems.
 Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
 Be careful when connecting service equipment.
 Do not breathe refrigerant or vapor.
The air conditioning system uses HFC- 134a (R-134a)
refrigerant and polyalkyleneglycol (PAG) refrigerant oil,
which are not compatible with CFC-12 (R-12) refrigerant
or mineral oil. Do not use R-12 refrigerant or mineral oil
in this system, and do not attempt to use R-12 servicing
equipment; damage to the air conditioning system or
your servicing equipment will result.
Use only service equipment that is U.L.-listed and is
certified to meet the requirements of SAE J2210 to
remove R-134a from the air conditioning system.
If accidental system discharge occurs, ventilate the
work area before resuming service.
R-134a service equipment or vehicle air c onditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
 Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
 Keep moisture and dirt out of the system. When disconnecting any lines, plug or cap the fittings
immediately; don’t remove the caps or plugs until
just before you reconnect each line.
 Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.
 When tightening or loosening a fitting, use a second wrench to support the matching fitting.
 When discharging the system, use an R-134a refrigerant recovery/recycling/charging station; don’t
release refrigerant into the atmosphere. Before troubleshooting any problem with the air
conditioning system, do the following:
1. With the ignition switch in LOCK (0), inspect the A/C components, the pressure lines, and the hoses for
stains that may indicate a refrigerant or a
compressor oil leak.
2. Check the A/C condenser (A) for material clogging the fins or for damage to the fins:
 Carefully clean any material from the A/C condenser fins with water and detergent. If
deeper cleaning is required, clean the fins with
Honda brite cleaner (P/N 08732-0020B).
 Be sure to dry the A/C condenser completely.
 Refer to the Refrigerant Leak Check (see page 21-93) to confirm leaks if there is visible damage
to the A/C condenser.
Check for stains.

 Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
 Be careful when connecting service equipment.
 Do not breathe refrigerant or vapor.
NOTE:  If accidental system discharge occurs, ventilate the work area before resuming service.
 Additional health and safety information may be obtained from the refrigerant and lubricant
manufacturers.
 Check the system for leaks using an R-134a refrigerant leak detector with an accuracy of 14 g
(0.5 oz) per year or better.  Position the vehicle in a wind-free work area. This will
aid in detecting small leaks.
 When using the leak detector for the first time, allow it to warm up for 2 minutes with the probe in a clean
atmosphere. This lets the temperature sensor in the
detector stabilize.
 The calibration check should be done in the ‘‘Search 2’’ mode. Once that is done, the other check
modes do not need calibrating.
 When leak checking through the HVAC module drain hose, avoid drawing water into the probe. Water can
damage the internal pump and sensor.
 Avoid creasing the flexible probe extension. Creases can restrict air flow and give false readings.
 Because the detector recalibrates itself for ambient gases, it may be necessary to move the detector
away from the leak to clear the sensor. Once the
sensor has cleared, recheck the suspected leak.
 When removing the clear probe tip, be careful not to lose the flow ball.
 R-134a is heavier than air; always check below and to the sides of all potential leak sources.
 Halogen leak detectors are sensitive to chemicals: windshield washing solutions, solvents/cleaners, and
some vehicle adhesives. Keep these chemicals out of
the area when doing leak detection.
