Irregular and/or Premature Wear DescriptionS7RS0B2401003
Irregular and premature wear has many causes. Some 
of them are as follows: incorrect inflation pressures, lack 
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is 
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is  necessary if following 
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with  “feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear 
indicators (1) to show when they need replacement.
These indicators (1) will app ear as 12 mm (0.47 in) wide 
bands when the tire tread depth becomes 1.6 mm (0.063 
in).
When the indicators (1) appear in 3 or more grooves at 6 
locations, tire replacement is recommended.
I2RH01240003-01
[A]: Hard Cornering, under inflation or lack of tire rotation
[B]: Incorrect wheel alignment, tire construction not uniform or wheel  heavy acceleration

Radial Tire Waddle DescriptionS7RS0B2401005
Waddle is side to side movement at the front and/or rear 
of the vehicle. It is caused by the steel belt not being 
straight within the tire. It is  most noticeable at a low 
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the f aulty tire by road testing the 
vehicle. If it is on the rear , the rear end of the vehicle 
shakes from side to side or “waddles”. To the driver in 
the seat, it feels as though someone is pushing on the 
side of vehicle.
If the faulty tire is on the  front, waddling is more visual. 
The front sheet metal appears to be moving back and 
forth and the driver feels as though he is at the pivot 
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem 
Detector (TPD) and following the equipment 
manufacture’s recommendations.
If TPD is not available,  an alternative method of 
substituting known-good tire / wheel assemblies can be 
used as follows, although it takes a longer time. 1) Ride vehicle to determine whether the front or rear 
waddles.
2) Install tires and wheels that are known to be good  (on similar vehicle) in place of those on waddling end 
of vehicle. If waddling  end cannot be identified, 
substitute rear ones.
3) Road test again. If improvement is noted, reinstall  originals one at a time till w addle causal tire is found. 
If no improvement is noted, install known-good tires 
in place of all four. Then reinstall originals in the 
same manner.

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.
1. Heavy spot wheel tramp [A]: Before correction
2. Balance weights addition point [B]: Corrective weights
3. C/L of spindle

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.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
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 vari ous speeds to determine 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 
wheel alignment and front suspension attachments for 
looseness. See diagnosis  table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight 
drop in reservoir level does  result from normal lining 
wear, an abnormally low leve l indicates a leak in the 
system. In such a case, chec k the entire brake system 
for leakage. If even a slight ev idence of leakage is noted, 
the cause should be corrected or defective parts should 
be replaced.
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 components in 
the hydraulic system to deteriorate.

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 system, 
including hoses. Also, when working on the brake 
mechanisms, check for fluid on the linings. 
If excessive fluid is found, replace the pads. If master cylinder piston seals 
are satisfactory, check for 
leakage or excessive heat co nditions. If leakage 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.
