Radial Tire Lead / Pull DescriptionS7RS0B2401006
“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 DescriptionS7RS0B2401007
There are two types of wheel an d 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.

Repair Instructions
General Balance ProceduresS7RS0B2406001
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING!
Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each 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 the 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.
WARNING!
Wheel spin should be limited to 55 km/h (35
mph) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION!
Using on-vehicle balancing method with
ignition switch ON may set malfunction
diagnostic trouble code (DTC) of ESP® and
ABS even when system is in good condition.
Never turn ignition swit ch ON while spinning
wheel.

Tire RotationS7RS0B2406002
To equalize wear, rotate tires according to figure. Radial
tires should be rotated periodi cally. Set tire pressure.
[A]: Rotation direction is not indicated.
[B]: Rotation direction is indicated.

General Description
Brakes ConstructionS7RS0B4101001
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pistons (two
in front and two in rear).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they make two
independent circuits. One connects front right & rear left brakes and the other connects front left & rear right brakes.
In this brake system, the disc brake type is used for the front wheel brake and the rear wheel brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes or pads are used for both parking and foot brakes.

Should a front crash occur and the engine push the dash panel toward the interior side, the brake pedal bracket is also
pushed toward the interior side. In this case, the brake pedal lever comes off from the brake pedal, thereby preventing
the brake pedal from moving rearward.
CAUTION!
Never disassemble brake pedal assembly. Disassemble will spoil its original function. If faulty
condition is found, replace it with new one.
