brake rotor.
• Check and adjust the brake fluid level in the reservoir as necessary.
• Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the
brake pads.
• After installation and before moving the vehicle, pump the brake pedal several times to set the pads to the
brake rotor.
Inspection
Visually inspect brake pads for uneven lining wear. Also inspect for excessive lining deterioration. Check the clear-
ance between the tips of the wear indicators (if equipped) on the pads and the brake rotors. If a visual inspection
does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount
of lining wear, remove the disc brake pads from the vehicle. Measure the brake pad minimum thickness. Brake pads
must be replaced when usable material on a brake pad lining measured at its thinnest point measures one millimeter
or less. Replace both disc brake pads (inboard and outboard) at each caliper. It is also necessary to replace the pads
on the opposite side of the vehicle as well as the pads failing inspection to maintain proper braking characteristics.
If the brake pad assemblies do not require replacement, be sure to reinstall the brake pads in the original position
from which they were removed.
Rear Brake Pads
Removal & Installation
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the tire and wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
NOTE :
In some cases, it may be necessary to retract the caliper piston in its bore a small amount in order to provide suf-
ficient clearance between the pads and the rotor. 3. Remove the lower rear caliper guide pin bolt (2). (Tighten: Rear caliper guide pin bolt to 23 N·m)
CAUTION: When moving rear brake caliper
upward, use extreme care not to damage or
overextend the flex hose.
4. Rotate the caliper (1) upward hinging off the upper guide pin bolt. Rotate the caliper upward just
enough to allow brake pad removal.
5. Slide the rear brake pads off of the brake caliper adapter.

13. If a slugging condition still exists after replacing the A/C accumulator, replace the A/C compressor.
Refrigerant System Leaks
WARNING!
R-134a service equipment or vehicle A/C systems should not be pressure tested or leak tested with compressed
air. Mixture of air and R-134a can be combustible at elevated pressures. These mixtures are potentially danger-
ous and may result in fire or explosion causing property damage, personal injury or death. Avoid breathing A/C
refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved service
equipment meeting SAE requirements to discharge an R-134a system. If accidental system discharge occurs,
ventilate work area before resuming service.
NOTE :
If the A/C refrigerant system charge is empty or low, a leak in the A/C system is likely. Inspect all A/C lines, fittings
and components for an oily residue. Oil residue can be an indicator of an A/C system leak location.
NOTE :
The only way to correctly determine if the refrigerant system is fully charged with R-134a is to completely evacuate
and recharge the A/C system.
Refrigerant System Empty
1. Evacuate the refrigerant system to the lowest degree of vacuum possible. Determine if the system holds a vac- uum for 15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum level,
proceed to STEP 2.
2. Prepare and dispense 0.3 kilograms of R-134a refrigerant into the evacuated refrigerant system and proceed to STEP 1 of the System Low procedure.
Refrigerant System Low
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
2. Operate the heating-A/C system with the engine at idle under the following conditions for at least 5 minutes:Doors or windows open, transaxle in Park or Neutral with the parking brake set (depending on application), A/C-
Heater controls set to outside air, full cool, panel mode, high blower and with A/C compressor engaged.
3. Shut the vehicle Off and wait2-7minutes. Then use an electronic leak detector that is designed to detect R-134a refrigerant and search for leaks. Fittings, lines or components that appear to be oily usually indicate a
refrigerant leak. To inspect the A/C evaporator for leaks, insert the leak detector probe into the drain tube open-
ing or an air outlet. A dye for R-134a is available to aid in leak detection. Use only approved refrigerant dye.
CAUTION:
A leak detector only designed for R-12 refrigerant will not detect leaks in an R-134a refrigerant sys-
tem.
