9) Upon completion of all jobs, depress brake pedal
with about 300 N (30 kg, 66 lbs) load at least 3 times
so as to obtain proper drum-to-shoe clearance.
Adjust parking brake cable. For adjustment, see
“Parking Brake Inspection and Adjustment in Section
4D”.
10) Check to ensure that brake drum is free from
dragging and proper braking is obtained.
11) Perform brake test (foot brake and parking brake).
12) Check each installed part for fluid leakage.

Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement tires should be of the same size, load
range and construction as those originally on the vehicle.
Use of any other size or type tire may affect ride,
handling, speedometer / odometer calibration, vehicle
ground clearance and tire or snow chain clearance to the
body and chassis.
It is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to
equalize braking traction.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.

The metric term for tire inflation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown in the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS6RW0D2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
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 “a” and radial
runout “b” at both inside and outside of the rim flange.
With the 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 correction 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 “a”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.9 mm (0.035 in.)
Radial runout limit “b”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.7 mm (0.028 in.)
Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If a broken stud is found, see “Front Wheel Hub, Disc,
Bolt and Bearing Check in Section 2B”, “Front Wheel
Hub, Steering Knuckle and Wheel Bearing Removal and
Installation in Section 2B”, “Rear Wheel Hub Assembly
Removal and Installation in Section 2C”. kPa kgf/cm

Equipment manufacture’s recommendations
Radial Tire Lead / Pull DescriptionS6RW0D2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from
the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
• Rear tires will not cause lead.
Balancing Wheels DescriptionS6RW0D2401007
There are two types of wheel and tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.Dynamic balance, as shown in figure, is the equal
distribution of weight on each side of the 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.
Inflate tires to recommended pressure
Road test vehicle on level unrouned road in both directions
Switch front tires side to side and road test again
Lead corrected,
if roughness results, replace tiresLeads in same directionLeads reverses direction
Put tires back in original position
and check alignmentInstall a known-good tire on one front side
Lead remains install a known-good
tire in place of other front tire
Lead remains known-good tires are not goodLead corrected replace tire
Lead corrected replace tire
