angle with turning radius gauges.
If steering angle is not correct, check if right and left tie-rods are
equal in length (ªAº in left figure).

NOTE:
If tie rod lengths were changed to adjust steering angle, rein-

Reference Information:
Side slip:
For inspecting front wheel side slip with side slip tester:
Side slip limit: Less than 3 mm / m
(Less than 0.118 in. / 3 ft)
If side slip exceeds above limit, toe-in or front wheel alignment may
out not be correct.

POWER STEERING (P / S) SYSTEM 3B1-3
STEERING GEAR BOX
The steering gear box consists of two sections: one including a cyl-
inder and the other a valve. Main components of the cylinder sec-
tion are a gear box, a rack and a tube and those of the valve section
are a valve case, a sleeve and a stub shaft. The sleeve is linked with
the pinion through a pin and the valve and stub shaft are integrated
into one unit. Then the pinion and the stub shaft are linked to each
other by means of the torsion bar.
Thus, when the stub shaft moves, the valve changes its position,
thereby switching the hydraulic passage from the pump to the cylin-
der to help steering operation.
When turning the steering wheel feels heavy due to P / S fluid leak-
age or for some other reason (i.e., when in the manual steering
mode), the stub shaft and pinion are in direct linkage and the force
is output directly through the pinion and rack.

WHEELS AND TIRES 3F-7
TIRE
MOUNTING AND DEMOUNTING
Use tire changing machine to mount or demount tires. Follow equip-
ment manufacturer's instructions. Do not use hand tools or tire
irons alone to change tires as they may damage tire beads or wheel
rim.
Rim bead seats should be cleaned with wire brush or coarse steel
wool to remove lubricants, old rubber and light rust. Before mount-
ing or demounting tire, bead area should be well lubricated with ap-
proved tire lubricant.
After mounting, inflate to 240 kPa (35psi) so that beads are com-
pletely seated. Then adjust pressure to specified shown an tire
placard.
WARNING:
Do not stand over tire when inflating. Bead may break when
bead snaps over rim's safety hump and cause serious per-
sonal injury.
Do not exceed 240 kPa (35 psi) pressure when inflating. If
240 kPa (35 psi) pressure will not seat beads, deflate, re-lu-
bricate and reinflate. Over inflation may cause bead to break
and cause serious personal injury.
Install valve core and inflate to proper pressure.
TIRE REPAIR
There are many different materials and techniques on the market
to repair tires. As not all of these work on all types of tires, tire
manufacturers have published detailed instructions on how and
when to repair tires. These instructions can be obtained from the
tire manufacturer.

FLUSHING BRAKE HYDRAULIC SYSTEM
It is recommended that entire hydraulic system be thoroughly
flushed with clean brake fluid whenever new parts are installed in
hydraulic system.
Periodical change of brake fluid is also recommended.
FLUID PRESSURE TEST(if equipped with
LSPV)
Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.

Fuel tank is filled with fuel fully.

Vehicle is equipped with spare tire, tools, jack and jack handle.
1) Stop vehicle on level floor and place approximately about
200 kg (441 lbs) weight on rear housing so that rear axle weight
800 kg (1764 lb).
Rear axle weight ªLº: 800 kg (1764 lb)
2) Install special tool to front and rear brake.
NOTE:
Special tool should be connected to breather of front (driv-
er's side brake) and rear brakes.

(B): 09952-46510 (Attachment for vehicle with SUMITOMO
ELECTRIC brake caliper)
(C): 55473-82030 (Air bleeder plug supplied as a spare part)
Rear brake
(A): 09956-02310
(B): 09952-36310 (Attachment for thread diameter 7 mm of
bleeder plug) or
09952-46510 (Attachment for thread diameter 8 mm of
bleeder plug)
(C): 55473-82030 (Air bleeder plug supplied as a spare part)
NOTE:

Special tool (B) is used instead of thread diameter 10 mm
attachment of special tool (A).
So remove the attachment from (A) and install (B) as
shown in figure.

For vehicle with TOKICO brake caliper, use the attach-
ment included in special tool (A).

For identification of brake caliper type, refer to GENERAL
DESCRIPTION in SECTION 5B.

6) Upon completion of fluid pressure test, bleed brake system and
perform brake test.
BOOSTER OPERATION CHECK
There are two ways to perform this inspection, with and without a
tester. Ordinarily, it is possible to roughly determine its condition
without using a tester.
NOTE:
For this check, make sure that no air is in hydraulic line.
INSPECTION WITHOUT TESTER
Check Air Tightness
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in ordi-
nary braking and observe pedal travel. If pedal goes down deep
the first time but its travel decreases as it is depressed the se-
cond and more times, air tightness is obtained.
4) If pedal travel doesn't change, air tightness isn't obtained.
NOTE:
If defective, inspect vacuum lines and sealing parts, and re-
place any faulty part.
When this has been done, repeat the entire test.

Check Operation
1) With engine stopped, depress brake pedal several times with
the same load and make sure that pedal travel doesn't change.
2) Start engine while depressing brake pedal. If pedal travel in-
creases a little, operation is satisfactory. But no change in pedal
travel indicates malfunction.
Check Air Tightness Under Load
1) With engine running, depress brake pedal. Then stop engine
while holding brake pedal depressed.
2) Hold brake pedal depressed for 30 seconds. If pedal height does
not change, condition is good. But it isn't if pedal rises.

5E1-2 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
GENERAL DESCRIPTION
The ABS (Antilock Brake System) controls the fluid pressure applied to the wheel cylinder of each brake from the
master cylinder so that each wheel is not locked even when hard braking is applied. This ABS is a 4-wheel type
which controls the fluid pressure applied to the wheel cylinder of each of the four brakes to prevent each wheel
from getting locked.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.

Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.

In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor relay and fail-safe relay
are combined as one component.

ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to each
wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.

ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure applied
to wheel cylinder of each of 4 wheels.

Fail-safe (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and pump motor
relay.

Pump motor relay which supplies power to pump motor in ABS hydraulic unit.

ªABSº warning lamp which lights to inform abnormality when system fails to operate properly.

G sensor which detects body deceleration speed. (For 4WD model only)
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sensor
independently of change of load due to load capacity and so on. And if the EBD system fails to operate properly,
the brake warning lamp lights to inform abnormality.
