NOTE(1) Tooth contact pattern is a method for judging the result of the adjustment of drive pinion height and final drive gear
backlash. The adjustment of drive pinion hight and final drive gear backlash should be repeated until tooth contact
patterns bear a similarity to the standard tooth contact pattern.
(2)When adjustment is not able to obtain a correct pattern, it may be judged that the drive gear and drive pinion have
exceed their usage limits and both gears should be replaced as a set.

SERVICE ADJUSTMENT PROCEDURES
BRAKE PEDAL INSPECTION AND ADJUSTM&g
1.Measure the brake pedal height as illustrated. If the brake
pedal height is not within the standard value, adjust as
follows.
Standard value (A): 176181 mm (6.9-7.1 in.)(1) Disconnect the stop light switch connector, loosen the
lock nut, and move the stop light switch to a position
where it does not contact the brake pedal arm.
(2) Adjust the brake pedal height by turning the operating
rod with pliers (with the operating rod lock nut
loosened), until the correct brake pedal height is
obtained.(3) After screwing in the stop light switch until it contacts
the brake pedal stopper (just before the brake pedal is
caused to move), return the stop light switch
l/2 to 1turn and secure by tightening the lock nut.
(4) Connect the connector of the stop light switch.
(5) Check to be sure that the stop light is not illuminated
with the brake pedal unpressed.
Reference value (B): 0.5-1.0 mm
(.02-M in.)
2. With the engine stopped, depress the brake pedal two or
three times. After eliminating the vacuum in the power
brake booster, press the pedal down by hand, and confirmthat the amount of movement before resistance is met
(the free play) is within the standard value range.
Standard value
(C): 3-8 mm (.l-.3 in.)
If the free play is less than the standard value, confirm thatthe clearance between the stop light switch and brake
pedal is within the standard value.
If the free play exceeds the standard value, it is probably
due to excessive play between the
clevis pin and brake
pedal arm. Check for excessive clearance and replace
faulty parts as required.
3. Start the engine, depress the brake pedal with approxi-
mately 500 N (110 Ibs.) of force, and measure the clearancebetween the brake pedal and the floorboard.
Standard value (D): 80 mm (3.1 in.) or moreIf the clearance is less than the standard value, check for
air trapped in the brake line and for brake fluid leaks. If
necessary, check the brake system mechanism (excessiveshoe clearance due to faulty auto adjuster) and repair
faulty parts as required.

Caution
If the number of brake lever notches engaged is less
than the standard value, the cable has been pulledexcessively, and failure of the automatic adjuster
mechanism will result. Be sure tti adjust it to within the
standard value.(6) After making the adjustment, check to be sure that there is
no play between the adjusting nut and the pin. Also check
to be sure that the adjusting nut is securely held at the nut
holder.(7) After adjusting the lever stroke, jack up the rear of the
vehicle.(8) With the parking brake lever in the released position, turn
the rear wheel to confirm that the rear brakes are not
dragging.
PARKING BRAKE SWITCH CHECKN05FDAB
(1) Disconnect the connector of the parking brake switch, and
connect an ohmmeter to the parking brake switch and the
switch installation bolt.
(2) The parking brake switch is good if there is continuity whenthe parking brake lever is pulled and there is no continuity
when it is returned.
BRAKE BOOSTER OPERATING
lNSPECTIONNoSFcuFor simple checking of brake booster operation, carry out the
following tests.
(1) Run the engine for one or two minutes, and then stop it.
(2) Step on the brake pedal several times with normal
pressure.If the pedal depressed fully the first time. but gradually
becomes higher when depressed succeeding times, the
booster is operating properly.
If the pedal height remains unchanged, the booster is
faulty.(3) With the engine stopped, step on the brake pedal several
times with the same pressure to make sure that the pedal
height will not change.
Then step on the brake pedal and start the engine.
If the pedal moves downward slightly, the booster is in
good condition. If there is no change, the booster is faulty.
(4) With the engine running, step on the brake pedal and then
stop the engine.
Hold the pedal depressed for 30 seconds. If the pedal
height does not change, the booster is in good condition.
If the pedal rises, the booster is faulty.
If the above three tests are okay, the booster performance canbe determined as good.
If one of the above three tests is not okay at last, the check
valve, vacuum hose, or booster will be faulty.

pin play are not within the standard value range, adjust as
follows
:(1) For vehicles without auto-cruise control system, turn
and adjust the bolt so that the pedal height is the
standard value, and then secure by tightening the lock
nut.Vehicles with auto-cruise control system, disconnect
the clutch switch connector and turn the switch for
standard clutch pedal height. Then lock with the lock
nut.
NOTE
When the pedal height is lower than the standard value,
loosen the bolt or clutch switch, and then turn the pushrod to make the adjustment. After making the adjust-
ment, tighten the bolt or clutch switch to reach the
pedal stopper, and then lock with the lock nut.
(2) Turn the push rod to adjust the clutch pedal clevis pin
play to agree with the standard value and then secure
the push rod with the lock nut.
CautionWhen adjusting the
pedal height or the clutch pedal
clevis pin play, be careful not to push the push rodtoward the master
cylinder.3. Check to be sure that the interlock switch is as shown in
the illustration when the clutch pedal is depressed its full
stroke
[151 mm (6.0 in.)]. If necessary, loosen the lock nut
and adjust.
4.After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of the
pedal pad) and the
firewall when the clutch is disengaged
are within the standard value ranges.

low
Possible cause:,
The driven bevel gear is further away from the drive bevel
gear than necessary.
Remedy:Use a thinner spacer for the driven bevel gear mount
adjustment so that the driven bevel gear is closer to the
drive bevel gear.
NOTE(1) If correct tooth contact cannot be obtained by replace-
ment of spacer for adjusting driven bevel gear mount,
change the spacers for adjustment of drive bevel gear
preload and drive bevel gear mount adjustment to thoseof appropriate thickness as described below and adjust
the tooth contact again.
lIf the driven bevel gear height is still too small whenthe thinnest spacer for driven bevel gear mount
adjustment
[0.13 mm (.005 in.)] is used;
Change the spacer for drive bevel gear mount
adjustment to the next thicker one and change the
spacer for drive bevel gear preload adjustment to
the next thinner one.
lIf the driven bevel gear height is still too large whenthe thickest spacer for driven bevel gear mount
adjustment
[0.52 mm (020 in.)] is used;
Change the spacer for drive bevel gear mount
adjustment to the next thinner one and change the
spacer for drive bevel gear preload adjustment to
the next thicker one.
Repeat above steps until standard tooth contact
pattern is obtained.
(2) If the tooth contact pattern cannot be brought close
,tothe standard pattern by the adjustment described
above, replace the drive bevel gear and driven bevel
gear as a set and adjust the tooth contact again.
