POWER BRAKE UNIT
FUNCTION CHECK
Simple Method
First step
1. With the engine stopped, depress the pedal a few
times.
2. With the pedal depressed, start the engine
3. If immediately after the engine starts the pedal
moves down slightly, the unit is operating.
Second step
1. Start the engine.
2. Stop the engine after it has run for
1
or 2 minutes.
3. Depress the pedal with the usual force.
4.
If
the first pedal stroke is long and becomes short-
er with subsequent strokes, the unit is operating.
5. If a problem is found, inspect for damage of the
check valve or vacuum hose, and examine the in-
stallation condition. Repair if necessary, and inspect
it once again.
Third step
1. Start the engine.
2. Depress the pedal with the usual force.
3. Stop the engine with the pedal still depressed.
4. Hold the pedal down for about 30 seconds.
5. If the pedal height does not change, the unit is
operating.
6. If there is a problem, check for damage to the
check valve or vacuum hose, and check the con-
nection. Repair if necessary, and check once
again.
If the nature of the problem is still not clear after fol-
lowing the 3 steps above, follow the more detailed
check described in "Method using tester".
Method Using Tester
Connect a pressure gauge, vacuum gauge, and ped-
al depression force gauge as shown in the figure. Af-
ter bleeding the air from the pressure gauge, conduct
the test as described in the 3 steps below.
Note
Use commercially available gauges and ped-
al depression force gauge.

VACUUM PUMP 1 1
INSPECTION
1. Check the rotor, housing and cover for wear or
damage.
2. Check the O-ring for deterioration or damage.
3. Check the vane for wear or damage. Replace if
necessary.
Height:
13.0—13.5 mm (0.512—0.530 in)
76G11X-041
4. Check the housing inner diameter.
Diameter:

FRONT WHEEL ALIGNMENT
86U13X-108
69G10X-031
Pre-inspection
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the front wheel bearing play and correct,
it if necessary.
3. Inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any
excessive looseness.
5. The vehicle must be on level ground and have no
luggage or passenger load.
6. The difference in height between the left and right
sides from the center of the wheel to the fender
brim must be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignment should be
checked simultaneously. If adjustment is
made to either the front or rear wheels,
recheck the alignment, particularly toe-in,
on all other wheels.
b) Check and adjust the steering angle trans-
fer shaft after adjusting the front wheel
alignment. (Refer to Section 10)
TOE-IN
Inspection
1. Raise the front of the vehicle until the wheels clear
the ground.
2. Turn the wheels by hand, mark a line in the center
of each tire tread using a scribing block.
3. Place the front wheels in the straight-ahead posi-
tion and lower the vehicle.
4. Measure the distance between the lines at the front
and rear of the wheels.
Both measurements must be taken at equal
distances from the ground.
Toe-in (distance greater at rear than front):
3 ± 3 mm (0.12 ± 0.12 in)
Adjustment
To adjust the toe-in, loosen the left and right tie-rod
lock nuts, then turn the tie-rods by the same amount.
Caution
a) The left and right tie-rods are both right
threaded, so, to increase the toe-in, turn the
right tie-rod toward the front of the vehicle,
and turn the left tie-rod by the same amount
toward the rear.
b) One turn of the tie-rod (both sides) changes
the toe-in by about 7.2 mm (0.28 in).
c) Tighten the tie-rod locknuts to the specified
torque.
Tightening torque: 69—98 N-m

REAR WHEEL ALIGNMENT
PRE-INSPECTION
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the wheel and tire runout.
3. The vehicle must be on level ground and have no
luggage or passenger load.
4. Check that the suspension is correctly adjusted.
5. The difference in height between the left and right
sides from the center of the wheel to the fender
rim should be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignments should be
checked simultaneously. If adjustment is
made to either the front or rear wheels,
recheck the alignment, particularly toe-in,
on all other wheels.
b) Check and adjust the steering angle trans-
fer shaft after adjusting the rear wheel align-
ment. (Refer to Section 10.)
TOE-IN
Inspection
1. Raise the rear of the vehicle until the wheels clear
the ground.
2. Turn the wheels by hand, mark a line in the center
of each tire tread using a scribing block.
3. Lower the vehicle.
4. Measure the distance between the marked lines
at the front and rear of the wheels.
Toe-in
0 ± 3 mm (0 ±0.12 in) 2WS
3 ± 3 mm (0.12 ±0.12 in) 4WS
Adjustment (2WS)
1. Loosen the adjusting rod lock nuts, then adjust the
toe-in.
2. To increase the toe-in, turn the adjusting rods as
follows:
Right rod — Turn counterclockwise
Left rod — Turn clockwise
To decrease the toe-in, turn the adjusting rods as
follows:
Right rod — Turn clockwise
Left rod — Turn counterclockwise
Caution
a) Both the left and right rods must be adjust-
ed by the same amount.
b) One turn of the adjusting rod (both sides)
changes the toe-in by about 11.6 mm (0.46
in).
3. Tighten the adjusting rod lock nuts to the speci-
fied torque.
Tightening torque:
55—80 N-m (5.6—8.2 m-kg, 41—59 ft-lb)

4. Apply a thin coat of primer to the bonding area of
the body and glass, and allow 30 minutes for it
to dry.
Caution
Keep the area free of dirt. Do not touch the
surface. If primer gets on the hands, remove
it immediately.
