3F-2 WHEELS AND TIRES
The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire
Placard. Metric tire gauges are available from tool suppliers. The

WHEELS REPLACEMENT
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in left figure may cause ob-
jectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may affect
wheel and bearing life, brake cooling, speedometer / odometer cal-
ibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use accurate dial
indicator. The tire may be on or off the wheel. The wheel should be
installed to the wheel balancer of the like for proper measurement.
Take measurements of both lateral runout and radial runout at both
inside and outside of the rim flange. With dial indicator set in place
securely, turn the wheel one full revolution slowly and record every
reading of the indicator.
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
Lateral runout limit ªaº: 1.20 mm (0.047 in.)
Radial runout limit ªbº: 1.20 mm (0.047 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).

DIAGNOSIS
DIAGNOSIS TABLE
Refer to SECTION 3.
BALANCING WHEELS
There are two types of wheel and tire balance: static and dynamic.
Static balance, as shown in left figure, is equal distribution of weight
around wheel. Wheels that are statically unbalanced cause bounc-
ing action called tramp. This condition will eventually cause uneven
tire wear.
Dynamic balance, as shown in left figure, is equal distribution of
weight on each side of wheel centerline so that when the tire spins
there is no tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause shimmy.
GENERAL BALANCE PROCEDURE
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING:
Stones should be removed from tread in order to avoid operator injury during spin balancing and to
obtain good balance.
Tire should be inspected for any damage, then balanced according to equipment manufacturer's recommendation.
OFF-VEHICLE BALANCING
Most electronic off-vehicle balancers are more accurate than on-vehicle spin balancers. They are easy to use and
give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does on-vehicle
spin balancing, this is overcome by their accuracy, usually to within 1 / 8 ounce.
ON-VEHICLE BALANCING
ON-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufacturer's
instructions during balancing operation.

MAINTENANCE AND MINOR ADJUSTMENTS
WHEEL AND TIRE
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
STUDS
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
MATCHED TIRES AND WHEELS
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or ªhigh spotº, is
matched to the smallest radius or ªlow spotº of the wheel.
This is done to provide the smoothest possible ride.
The ªhigh spotº of the tire is originally marked by paint dot on the
outboard sidewall. This paint dot will eventually wash off the tire.
The ªlow spotº of the wheel is originally marked by paint dot on the
wheel rim-flange. Properly assembled, the wheel rims' paint dot
should be aligned with the tires' paint dot as shown in left figure.
Whenever a tire is dismounted from its wheel, it should be re-
mounted so that the tire and wheel are matched. If the tire's paint
dot cannot be located, a line should be scribed on the tire and wheel
before dismounting to assure that it is remounted in the same posi-
tion.
INFLATION OF TIRES
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering, tread
wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for three hours or more, or driven less than one mile) should
be checked monthly or before any extended trip. Set to the specifications on the tire placard located on the side
of instrument panel.
It is normal for tire pressure increase when the tires become hot during driving. Do not bleed or reduce tire pressure
after driving. Bleeding reduces the ªCold Inflation Pressureº.

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.

BRAKES 5-3
SUBSTANDARD OR
CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid
may cause the brake fluid to boil or the rubber compo-
nents in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts
have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the
drum brake wheels.
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol
out of the system. Replace all rubber parts in the sys-
tem, including hoses. Also, when working on the
brake mechanisms, check for fluid on the linings. If ex-
cessive fluid is found, replace the linings.
If master cylinder piston seals are satisfactory, check
for leakage or excessive heat conditions. If condition
is not found, drain fluid, flush with brake fluid, refill and
bleed system.
The system must be flushed if there is any doubt as
to the grade of fluid in the system or if fluid has been
used which contained parts that have been subjected
to contaminated fluid.
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both
light and heavy pedal forces at various speeds to de-
termine if the vehicle stops evenly and effectively.
Also drive vehicle to see if it leads to one side or the
other without brake application. If it does, check the
tire pressure, front end alignment and front suspen-
sion attachments for looseness. See diagnosis chart
for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is
noted, the cause should be corrected or defective
parts should be replaced.
If fluid level is lower than the minimum level of reser-
voir, refilling is necessary. Fill reservoir with specified
brake fluid.
Brake fluid: Refer to reservoir tank cap.
CAUTION:
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious damage
will occur.
Do not use old or used brake fluid, or any fluid
from a unsealed container.

BRAKE PEDAL FREE HEIGHT CHECK
Remove foot rest and displace carpet and dash silencer(s) so as to
measure brake pedal free height between pedal face and asphalt
sheet installed on dash panel.
Brake pedal free height ªaº from asphalt sheet:
208 ± 218 mm (8.19 ± 8.58 in.)
If the measurement is not within the specification, check the posi-
tion of booster push rod clevis and / or stop light switch according
to the instruction shown in this section.
The free height varies depending on installation position of booster
push rod clevis and stop light switch.
BRAKE LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when installing switch. Pull
up brake pedal toward you and while holding it there, adjust switch
position so that clearance between end of thread and brake pedal
return cushion (shown as ªbº in figure).
Then tighten lock nut to specified torque.
Clearance ªbº: 1.5 ± 2.0 mm (0.06 ± 0.08 in.)

EXCESSIVE PEDAL TRAVEL CHECK
1) Remove foot rest and displace carpet and dash silencer(s).
2) Start engine.
3) Depress brake pedal a few times.
4) With brake pedal depressed with approximately 30 kg (66 lbs)
load, measure pedal to asphalt sheet clearance ªcº.
Clearance ªcº: over 115 mm (4.53 in.)
5) If clearance ªcº is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or air
is in lines.
Should clearance ªcº remain less than specification even after
replacement of brake shoes and bleeding of system, other pos-
sible but infrequent cause is malfunction of rear brake shoe ad-
justers or booster push rod length out of adjustment.

(40 lbs) force.
With parking brake lever pulled up as shown, count ratchet
notches.
There should be 5 to 7 notches.
Also, check if both right and left rear wheels are locked firmly.
To count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its button.
One click sound corresponds to one notch.
If number of notches is out of specification, adjust cable by referring
to adjustment procedure described on the following as to obtain
specified parking brake stroke.
NOTE:
Check tooth tip of each notch for damage or wear. If any dam-
age or wear is found, replace parking brake lever.
ADJUSTMENT
