Clutch System
13.Clutch System
A: INSPECTION AND ADJUSTMENT
1) Push the release lever to retract the push rod of
the operating cylinder and check if the fluid level in
the clutch reservoir tank rises or not.
 Non-turbo model
 Turbo model
2) If the fluid level rises, pedal free play is correct.
3) If the fluid level does not rise, or the push rod
cannot be retracted, adjust the clutch pedal. to CL-34, Clutch Pedal.>
4) Check the fluid level using the scale on the out-
side of the clutch master cylinder tank (A). If the lev-
el is below “MIN” (B), inspect the clutch master
cylinder, operating cylinder and hydraulic line for
fluid leaks. If fluid leaks are found, repair or replace.
If fluid leaks are not found, add clutch fluid to bring
it up to “MAX” (C) of clutch reservoir tank.
Recommended clutch fluid:
FMVSS No. 116, fresh DOT3 or DOT4 brake
fluidCAUTION:
 Prevent the clutch fluid from being splashed
over vehicle body. If the clutch fluid is splashed
over vehicle body, flush it, and then wipe it up.
 Avoid mixing different brake fluid to prevent
degradation of the fluid.
 Be careful not to allow dirt or dust to get into
the reservoir tank.

Brake Line
(4) If there is no free play between clevis pin
and clevis, turn the brake switch adjusting nut
until the clearance between stopper and screw
of brake switch becomes 0.3 mm (0.012 in).
3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 490 N (50 kgf, 110 lb) load and measure the
distance between brake pedal and steering wheel.
With the brake pedal released, measure the dis-
tance between pedal and steering wheel again.
The difference between the two measurements
must be less than specified value. If the distance is
more than specified value, there is possibility of air
inside the hydraulic unit.
Brake pedal reserve distance: A
For Australia model
105 mm (4.13 in)/ 490 N (50 kgf , 110 lb) or less
Except for Australia model
90 mm (3.54 in)/ 490 N (50 kgf , 110 lb) or less4) Check to see if air is in the hydraulic brake line
by the feel of pedal operation. If air appears to exist
in the line, bleed it from the system.
5) Check for even operation of all brakes, using a
brake tester or by driving the vehicle for a short dis-
tance on a straight road.
2. BRAKE SERVO SYSTEM
1) With the engine off, depress the brake pedal
several times applying the same pedal force: Make
sure the travel distance should not change.
2) With the brake pedal depressed, start the en-
gine: Make sure the pedal should move slightly to-
ward the floor.
3) With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds:
Make sure the pedal height should not change.
4) Check valve is built into the vacuum hose. Dis-
connect the vacuum hose to inspect function of
check valve.
Blow air into the vacuum hose from its brake boost-
er side end: Air must flow out of engine side end of
hose. Next blow air into the hose from engine side:
Air should not to brake booster side.
Replace both check valve and vacuum hose if the
check valve is faulty. Engine side of vacuum hose
is indicated by marking “ENG” as shown in illustra-
tion.
5) Check the vacuum hose for cracks or other dam-
age.
CAUTION:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or
lubricating oil on their connections.
6) Check vacuum hose to make sure it is tight and
secure.

Brake Fluid
19.Brake Fluid
A: REPLACEMENT
1) Lift-up the vehicle.
2) Remove both front and rear wheels.
3) Draw out the brake fluid from master cylinder
with syringe.
4) Refill the reservoir tank with recommended
brake fluid.
Recommended brake fluid:
FMVSS No. 116, fresh DOT3 or DOT4 brake
fluid
CAUTION:
 Avoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
 Be careful not to allow dirt or dust to get into
the reservoir tank.
Bleeding sequence (1) → (2) → (3) → (4)
5) Install one end of a vinyl tube onto the air bleeder
and insert the other end of the tube into a container
to collect the brake fluid.
CAUTION:
 Cover the bleeder with waste cloth, when
loosening it, to prevent brake fluid from being
splashed over surrounding parts. During the bleeding operation, keep the
brake reservoir tank filled with brake fluid to
eliminate entry of air.
 The brake pedal operating must be very slow.
 For convenience and safety, two people
should do the work.
NOTE:
The amount of brake fluid required is approx. 500
m2 (16.9 US fl oz, 17.6 Imp fl oz) for total brake
system.
6) Instruct your co-worker to depress the brake
pedal slowly two or three times and then hold it de-
pressed.
7) Loosen the bleeder screw approx. 1/4 turn until a
small amount of brake fluid drains into container,
and then quickly tighten the screw.
8) Repeat steps 6) and 7) above until there are no
air bubbles in the drained brake fluid and new fluid
flows through vinyl tube.
NOTE:
Add brake fluid as necessary while performing the
air bleed operation, in order to prevent the tank
from running short of brake fluid.
9) After completing the bleeding operation, hold
brake pedal depressed and tighten the bleeder
screw and install bleeder cap.
Tightening torque:
8 N·m (0.8 kgf-m, 5.8 ft-lb)
10) Bleed air from each wheel cylinder by following
the previous 5 steps.
11) Depress the brake pedal with a force of approx.
294 N (30 kgf, 66 lb) and hold it there for approx. 20
seconds. At this time check the pedal to see if it
makes any unusual movement. Visually inspect the
bleeder screws and brake pipe joints to make sure
that there is no fluid leakage.
12) Install the wheels, and drive the vehicle for a
short distance between 2 to 3 km (1 to 2 miles) to
make sure that brakes are operating properly.

A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out.
If relative movement (B) is observed between the
brake disc cover (A) and end of transverse link (D),
ball joint (C) may be excessively worn.
3) Grasp the end of transverse link (C) and move it
up and down. Relative movement (A) between the
housing (D) and transverse link boss indicates ball
joint (B) may be excessively worn.
4) If relative movement is observed in the immedi-
ately preceding two steps, remove and inspect the
ball joint. If free play exceeds standard, replace the
ball joint.
5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the transverse link. Front Transverse Link.> And measure free play of
ball joint.
(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with the
new ball joint.
NOTE:
When the transverse link ball joint has been re-
moved or replaced, check the toe-in of front wheel. If the front wheel toe-in is not at specified value, ad-
just the toe-in.
2. TRANSVERSE LINK’S REAR BUSHING
Check oil leaks at around liquid-filled bushing. If oil
leaks, replace the bushing.
3. WHEEL ARCH HEIGHT
1) Unload cargoes and set the vehicle in curb
weight (empty) condition.
2) Then, check the wheel arch height of front and
rear suspensions to ensure that they are within
specified values.
3) When the wheel arch height is out of standard,
visually inspect the following components and re-
place deformed parts.
 Suspension components [Front strut assembly
and rear strut assembly]
