PARKING BRAKE (LEVER TYPE)
Inspection
Check that the stroke is within specification when the parking
brake lever is pulled with a force of 98 N (IO
kg, 22 lb).
Stroke: 5-7 notches
Adjustment
1. Before adjustment, start the engine and depress the brake
pedal several times while the vehicle is moving in reverse.
2. Stop the engine.
3. Remove the screw and the parking brake lever cover.
4. Remove the adjusting nut clip and turn the adjusting nut
at the front of the parking cable.
5. After adjustment, check the following points:
(1) Turn the ignition switch ON, pull the parking brake le
ver one notch, and check that the parking brake warn-
ing lamp illuminates.
(2) Verify that the rear brakes do not drag.

Caution
l Connect the charging hose to the air purge valve
via its tap pin side.
l Do not disconnect the charging hose or the serv-
ice container valve until the charging operation is
completed.
l Do not open the service container valve when not
used.
Charging from freon recovery and recycling system.
Connect the charging hose and stop valve to the manifold
gauge set air purge valve.
23UOUX-065
Caution
l Connect the charging hose to the air purge valve
via its tap pin side.
l Do not disconnect the charging hose or stop valve
until the charging operation is completed.
l Do not open the stop valve when not used.
4. Start the vacuum pump and open the high-and low-pressure
side valves of the manifold gauge set.
5. Start the pump and let it operate for 15 minutes.
6. Check high- and low-pressure side gauge readings. When
both of them are at 750 mmHg or more, close the manifold
gauge set valves.
7. Stop the vacuum pump and wait for about 5 minutes.
8. Verity that the low-pressure side gauge reading does not
change.
9. If the reading changes, retighten the piping connections and
repeat the evacuation operation.
10. If not changed, check for leaks (see below) and charge the
system.

Leak test
1. Carry out the system evacuation and airtightness test as
described above.
2. Prepare as follows according to charging method.
Charging from service container.
Connect the refrigerant service container to the service con-
tainer valve (which is connected to the manifold gauge set air
purge valve) and open the service container.
Charging from freon recovery and recycling system.
Connect the charging valve of the system to the stop valve
(which is connected to the manifold gauge air purge valve).

3. Open the high-pressure side valve of the manifold gauge
set. Charge the system until the low-pressuer side gauge
indicates 98.1 kPa. (1 kg/cm*, 14.22 psi).
4. Close the high pressure side valve.
5. Check for leaks at the system piping joints by using a gas
leak tester.
6. If leaks are found, check the O-rings and tightening torques
at the joints. Replace or retighten as necessary.
7. If no leaks are found, fully charge the system.
Caution
l Carry out the leak test in an well-ventilated but still
air area because it is affected by moving air.
23UOUX-071
Initial charging from service container
1. Carry out the system evacuation, airtightness test, and leak
test.
2. Open the high-pressure side valve of the manifold gauge
set and charge the system as specified.
Charging amount: Approx. 400 g (14.12 oz)
3. Close the high pressure side valve.
4. Start the engine and actuate the A/C compressor.
Caution
l Do not turn the service container upside down while
charging when the engine is running.
l Do not open the high-pressure side valve while the
engine is running.
5. Open the low-pressure side valve of the manifold gauge set
and charge the system to specification.
Specified total refrigerant amount: 800 g (28.24 oz) -.

6. Close the low-pressure side valve.
7. Stop the engine.
8. Close the stop valves and the service container valve.
Caution
l Do not disconnect the stop valves or the service
container valve from the charging hoses when there
is refrigerant remaining in the hoses.
Refilling
Caution
l Do not overcharge the system.
l Note the sight glass during refilling the refrigerant.
Stop charging when no bubbles are observed in the
glass.
(Refer to page U-40).
l Care must be taken when the ambient temperature
is low. The bubbles may not be present even if the
refrigerant amount is insufficient.
1. Connect the manifold gauge set to the refrigerant system
charging valve.
(Refer to page U-32).
2. Start the engine.
3. Open the low-pressure side valve of the manifold gauge set
and charge the system as necessary.
4. Note the sight glass, and when no bubbles can be seen,
close the low-pressure side valve.
5. Stop the engine.
6. Close the stop valve and service container valve. Discon-
nect the stop valves quickly.
