REPLACEMENT
1. REMOVE REAR WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the caliper inspection hole
and replace pads if not within the specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE BRAKE CALIPER
(a) Remove the 2 mounting bolts.
(b) Remove the caliper and suspend it so the hose is not
stretched.
HINT:
Do not disconnect the flexible hose.
4. REMOVE 2 PADS AND 4 ANTI-SQUEAL SHIMS
5. REMOVE 4 PAD SUPPORT PLATES
NOTICE:
The pad support plates can be used again provided that
they have sufficient rebound, no deformation, cracks or
wear, and have had all rust, dirt and foreign particles
cleaned off.
6. CHECK DISC THICKNESS AND RUNOUT
(See page BR-30)
7. INSTALL PAD SUPPORT PLATES
8. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti-squeal shims must be
replaced together with the pads.
Install the 4 anti-squeal shims to the pads.
HINT:
Apply disc brake grease to both sides of the inner anti-squeal
shims (See page BR-24).
NOTICE:
Do not allow oil or grease to get on the rubbing face.
9. INSTALL CALIPER
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or an equiva-
lent.
HINT:

Always change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.

If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some fluid escape.

ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). and check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage:
12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.

5. INSPECT DRIVE BELT
HINT:
A belt tensioner is used, so checking the belt tension is not nec-
essary.
(a) Visually check the drive belt for excessive wear, frayed
cords etc.
If necessary, replace the drive belt.
HINT:

Cracks on the rib side of a drive belt are considered ac-
ceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.

The drive belt tension can be released by turning the belt
tensioner counterclockwise. The pulley bolt for the belt
tensioner has a left-hand thread.
(b) Check the belt tensioner operation.

Check that the belt tensioner moves downward
when the drive belt is pressed down at the points in-
dicated in the illustration with approx. 98 N (10 kgf,
22.0 lbf) of force.

Check the alignment of the belt tensioner pulley to
make sure the drive belt has not slipped off the
pulley.
If necessary, replace the belt tensioner.

Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:

When a new belt is installed, it should lie within area B. If
not, the drive belt is not correct.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check by hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
6. REMOVE ENGINE UNDER COVER NO.1
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.

8. CHECK CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Switch off all accessories.
(c) Turn the ignition switch ON, and check that the charge
warning light is lit.
(d) Start the engine, and check that the light goes off.
If the light does not go off as specified, troubleshoot the charge
light circuit.
9. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:

Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (-) tester probe
of the ammeter.

Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.

Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.

Ground the negative (-) tester probe of the voltme-
ter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage:
10 A or less
Standard voltage:
13.2 - 14.8 V
If the value is not specified, check the generator.
10. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at HI.
(b) Check the reading on the ammeter.
Standard amperage:
30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.
11. REINSTALL ENGINE UNDER COVER NO.1
