8) Install transfer output flange (1) by tapping with
plastic hammer and tighten transfer output flange nut
gradually so as rotational torque of bevel pinion to be
in specified value.
NOTE
• If rotational torque of bevel pinion exceeds
specification given in the following,
replace pinion shaft spacers and tighten
flange nut.
• Before taking measurement of rotational
torque, rotate pinion over ten rounds in
advance.

Transfer Assembly InspectionS6RW0D3306010
• Check each bearing for smooth rotation, wear or
discoloration
If found abnormal, replace.
• Check oil seal for leakage and its lip for excessive
hardness
If either is found, replace.
• Check transfer case for cracks.
• Check bevel pinion and bevel gears for wear or
cracks.

4) Bring painted part up and check contact pattern referring to the following chart. If contact pattern is not normal,
readjust or replace as necessary according to instruction in chart.
NOTE
• Be careful not to turn bevel gear more than one full revolution, for it will hinder accurate check.
• If bevel gear back lash and bevel pinion shims are adjusted properly, correct tooth contact should
be provided.
If correct tooth contact is not provided even when they are adjusted properly, however, there may be
an abnormal condition in worn tooth, transfer case or retainer. Check each component and replace
as necessary.

Gear tooth contact table
Tooth contact pattern Diagnosis and remedy
Normal
High contact
Pinion is positioned too far from the center of drive bevel
gear.
• Decrease thickness of bevel pinion shim and position
pinion closer to gear center.
• Adjust drive bevel gear backlash to specification.
Low contact
Pinion is positioned too close to the center of drive bevel
gear.
• Increase thickness of bevel pinion shim and position
pinion farther from gear center.
• Adjust drive bevel gear backlash to specification.
These contact patterns indicate that the “offset” of
reduction driven gear is too much or too little. The
remedy is to change the division of the bevel gear
shim(s).

Repair Instructions
Brake Pedal ComponentsS6RW0D4106018
CAUTION!
If equipped Brake Pedal Foot Protection
System, never disassemble brake pedal
assembly. Disassemble will spoil its original
function. If faulty condition is found, replace
it with new one.

Brake Pedal Free Height InspectionS6RW0D4106001
1) Check brake pedal free height. If it is not within
specification, check and adjust following item 2) and
6).
Brake pedal free height “a” from carpet
111 – 131 mm (4.4 – 5.1 in.)
2) Check measurement between booster mounting
surface and center of clevis pin hole. When booster
push rod clevis has been reinstalled, it is important
that the measurement is adjusted (refer to “Brake
Booster Inspection”).
3) Check brake light switch position. Adjust it if it is out
of specification.
4) Check pedal for dent.
5) Check brake booster for installation.6) Check brake booster push rod for length.
Brake Pedal Play InspectionS6RW0D4106002
Pedal play should be within the following specification. If
out of specification, check brake light switch for proper
installation position and adjust if necessary.
Also check pedal shaft bolt and booster clevis pin
installation for looseness and replace if defective.
Brake pedal play
“a”
: 1 – 8 mm (0.04 – 0.31 in.)
Excessive Pedal Travel InspectionS6RW0D4106003
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 300
N (30 kg, 66 lbs) load, measure brake pedal to wall
(dash panel silencer) clearance “a”. If clearance is
out of specification, possible causes are as follows.
If clearance “a” is less than specification, the most
possible cause is that air is in lines or brake fluid
leakage.
Should clearance “a” remain less than specification
even after bleeding of system, other possible but
infrequent cause is malfunction of booster push rod
length out of adjustment.
• Bleed brake system. Refer to “Air Bleeding of
Brake System”.

Rear Brake Drum Removal and InstallationS6RW0D4306002
Removal
1) Hoist vehicle and remove rear wheel.
2) Release parking brake lever.
3) Remove brake drum (1) by using 8 mm bolts (2) (2
pcs).
Installation
1) Before installing brake drum, to maximize brake
shoe-to-drum clearance, put screwdriver between
rod and ratchet and push down ratchet.
NOTE
The figure show ratchet position where brake
shoe-to-drum clearance is maximum.

2) Confirm that inside of brake drum and brake shoes
are free from dirt and oil. And then install brake
drum.
3) Start engine and then depress brake pedal with
about 300 N (30 kg, 66 lbs) load at least 3 times until
adjuster actuator clicking sound from drum brake
can not be heard so as to obtain proper drum-to-
shoe clearance.
Adjust parking brake cable referring to “Parking
Brake Inspection and Adjustment in Section 4D”.
4) Install rear wheel.
5) Check to ensure that brake drum is free from
dragging and proper braking is obtained. Perform
brake test (foot brake and parking brake).
Rear Brake Drum and Shoe InspectionS6RW0D4306003
Brake Drum
Inspect brake drum for wear.
If drum inner diameter is exceeds the limit or uneven or
stepped wear is excessive, replace the drum.

Cracked, Scored or Grooved Drum
A cracked drum is unsafe for further service and must be
replaced. Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring
will cause excessive brake lining wear and it will
probably be necessary to resurface drum braking
surface.
If brake linings are slightly worn and drum is grooved,
drum should be polished with fine emery cloth in the
direction of drum depth but not circumferentially along
drum inner.
NOTE
When drum is removed, visually inspect
wheel cylinder for brake fluid leakage.
Correct leaky point, if any.

Brake Shoe
Measure thickness of brake shoe (1). Also, check
surface of lining for hardening, excessive wear and oil.
Rear brake shoe lining thickness
“a”
Standard: 4.0 mm (0.157 in.)
Limit: 1.0 mm (0.04 in.)
CAUTION!
Never polish lining with sandpaper. If lining is
polished with sandpaper, hard particles of
sandpaper will be deposited in lining and
may damage drum. When it is required to
correct lining, replace it with a new one.

Rear Brake Shoe On-Vehicle InspectionS6RW0D4306004
Amount of brake shoe wear can be checked as follows.
1) Hoist vehicle.
2) Remove rubber cover (plug) (1) from brake back
plate.
3) Through hole of back plate, visually check for
thickness of brake shoe lining (2). If lining thickness
is less than specified wear limit, replace all brake
shoes with new ones.
Lining thickness “a”
Service limit: 1.0 mm (0.04 in.)
Rear Brake Shoe Removal and InstallationS6RW0D4306005
NOTE
When replacing brake shoe, replace it on the
right and left.

Removal
1) Remove brake drum referring to “Rear Brake Drum
Removal and Installation”.
2) Push and rotate 90° hold down pin (1) and remove
hold down pin (1) and hold down spring (2).

6) Remove parking brake shoe lever (2) from shoe rim
(3).
Installation
Install parts in reverse order of removal, noting the
following.
• Before installing rear brake shoe to brake back plate,
clean brake back plate and apply heat-resistance
brake grease to A on which shoe rims rest.
• Push and rotate 90° hold down pin and install hold
down pin and hold down spring.
• Install brake drum referring to “Rear Brake Drum
Removal and Installation”.Rear Brake Shoe InspectionS6RW0D4306006
• Check ratchet of brake adjuster (1) assembly for wear
or damage.
• Check shoe return spring, antirattle spring, quadrant
spring and shoe hold down spring for damage,
corrosion and weakening.
• Check for smooth movement of brake shoe lever (2)
along shoe rim.
If any defective or malfunction is found, repair or replace.
Wheel Cylinder Removal and InstallationS6RW0D4306007
Removal
1) Remove brake drum referring to “Rear Brake Drum
Removal and Installation”.
2) Remove brake shoe referring to “Rear Brake Shoe
Removal and Installation”.
3) Loosen brake pipe flare nut (1) but only within the
extent that fluid does not leak.
4) Remove wheel cylinder mounting bolt (3).
Disconnect brake pipe from wheel cylinder and put
bleeder plug cap (2) onto pipe to prevent fluid from
spilling.
