1.
CHECK PEDAL HEIGHT
Pedal height from asphalt sheet:
150.0 – 160.0 mm (5.906 – 6.299 in.)
2.
IF NECESSARY, ADJUST PEDAL HEIGHT
(a)
Remove the No. 1 under cover, end pad, No. 1 safety pad
and No. 7 heater to register duct (See page
(b)
Disconnect the connector from the stop light switch.
(c)
Loosen the stop light switch lock nut and remove the stop
light switch.
(d)
Loosen the push rod lock nut.
(e)
Adjust the pedal height by turning the pedal push rod.
(f)
Tighten the push rod lock nut.
Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(g)
Install the stop light switch.
(h)
Push in the brake pedal 5 – 15 mm (0.20 – 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(i)
Connect the connector to the stop light switch.
(j)
After installation, push in the brake pedal 5 – 15 mm (0.20
– 0.59 in.), check that stop light lights up.
(k)
After adjusting the pedal height, check the pedal freeplay.
(l)
Install the No. 7 heater to register duct, No. 1 safety pad,
end pad and No. 1 under cover.
3.
CHECK PEDAL FREEPLAY
(a)
Stop the engine and depress the brake pedal more than
40 times until there is no more pressure left in the booster.
(b)
Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance, as
shown.
Pedal freeplay: 0.2 – 2.0 mm (0.008 – 0.079 in.)
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 – 2.4 mm (0.020 – 0.094 in.)
HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis and pin. It is 0.2 – 2.0 mm (0.008 – 0.079 in.)
on the pedal.

4.
CHECK PEDAL RESERVE DISTANCE
(a)
Remove the floor carpet.
(b)
Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance at 196 N (20 kgf, 44.1 lbf):
More than 93 mm (3.66 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

ON–VEHICLE INSPECTION
CAUTION:
Check that the battery cables are connected to the
correct terminals.
Disconnect the battery cables when the battery is giv-
en a quick charge.
Do not do tests with a high voltage insulation resis-
tance tester.
Never disconnect the battery while the engine is run-
ning.
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). 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 POSITIVE 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 positive voltage between the nega-
tive (–) 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.
4.
CHECK BATTERY TERMINALS AND FUSES
(a)
Check that the battery terminals are not loose or cor-
roded.
If the terminals are corroded, clean the terminals.
(b)
Check the fusible link and fuses for continuity.
