lTo correct unbalance, install equal weights 180° opposite
each other, one on the inside of the wheel and one on
the outside, at the point of unbalance.

6. Cautions for installation and removal.
lClean the mounting surfaces of hub and wheel.
lDo not apply grease or oil on the nuts and bolts (It will
cause looseness and poor tightening).
lUsing a jack, lift up the tire about 3cm from the ground.

BLEEDING THE BRAKES
For Master Cylinder Replacement
1. Add oil after master cylinder replacement.
2. Run the engine and depress the brake pedal several times
to build pressure and then keep the pedal fully depressed.
3. Loosen the screws of primary and secondary pipe at the
master cylinder outlets to bleed air.
4. Repeat above step No.3 several times until there are no
more air bubbles.
5. Bleed air in the system at the hydraulic unit outlet pipe and
wheel if pressure building is not enough by depressing the
pedal only after above air bleeding.
For Caliper and Brake Hose Replacement
1. Check the oil level from the oil reservoir and refill if necessary.
2. Run the engine and depress the pedal several times to
build pressure and then keep the pedal fully depressed.
3. Connect a vinyl tube to the caliper breather and prepare a
container to coentain brake oil.
4. Loosen the breather screw until there are no more bubbles.
5. Bleed air in the system at four (4) wheels in order as shown
in right figure if pressure building is not enough by depressing
the pedal after above air bleeding.

ANTILOCK BRAKE SYSTEM 4F-7
ABD SYSTEM DESCRIPTION
General:
The Automatic Brake Differential Lock (ABD) is a traction system by means of brake intervention only, available in
a low speed range (< 60kph).
It workes on m-split roads with sidewise different friction coefficients.
The spinning driven wheel is braked and the drive torque can be transferred to the wheel on the high- m side.
During ABD active, the ABD information lamp is blinking.
The temperature of the brakes is calculated by a mathematical model and ABD is switched passive if the calculated
temperature is greater than a threshold value(500°C).
ABD is permitted again, when the calculated temperature is less than 350°C.
Control Algorithm:
The input signals for the control algorithm are the filtered
wheel speed signals from the ABS speed processing.
With the speed difference of the driven wheels, the control
deviation is calculated.
If the control deviation exceeds a certain threshold value,
the wheel with the greater slip is braked actively.
The threshold value depends on the vehicle speed:
It is reduced with increasing vehicle speed down to a constant
value.
Pressure Modulation:
Depending on the control deviation and the wheel acceleration of the spinning wheel, pressure increase, hold and
decrease are made.
The pressure modulation is done with the conventional control with the valves. ASV, USV, EV and AV according
the the following table:
Speed Range:
ABD is available in the speed range £ 60 kph.
Above 60 kph vehicle speed, ABD is passive.
It is possible to initiate ABD operation up to a vehicle speed of 55kph.

5A-42 AUTOMATIC TRANSMISSION
POWER TRAIN SYSTEM
The Power Train System consists of:
lA torque converter with single face lock-up clutch
lFour multi-plate clutch assemblies
lTwo brake bands
lTwo one-way clutches
lPlanetary gearset
lParking mechanism
A conventional six pinion Ravigneaux compound planetary gearset is used with overdrive (fourth gear) being obtained
by driving the carrier.
The cross-sectional arrangement is very modular in nature. Four main sub-assemblies are installed within the case
to complete the build. These sub-assemblies are:
lGearset-sprag-centre support
lC1 -C2-C3-C4 clutch sub-assembly
lPump assembly
lValve body assembly
One, or a combination of selective washers are used between the input shaft flange and the number 4 bearing to
control the transmission end float. This arrangement allows for extensive subassembly testing and simplistic final
assembly during production.
A general description of the operation of the Power Train System is detailed below. Refer to table 4.1 and figure 4.1.
First gear is engaged by applying the C2 clutch and locking the 1-2 One Way Clutch (1-2 OWC). The 1-2 shift is
accomplished by applying the B1 band and overrunning the 1-2 OWC. The 2-3 shift is accomplished by applying the
C1 clutch and releasing the B1 band. The 3-4 shift is accomplished by re-applying the B1 band and overrunning the
3-4 OWC. Reverse gear is engaged by applying the C3 clutch and the B2 band.
The C4 clutch is applied in the Manual 1,2 and 3 ranges to provide engine braking. In addition, the C4 clutch is also
applied in the Drive range for second and third gears to eliminate objectionable freewheel coasting. The B2 band is
also applied in the Manual 1 range to accomplish the low-overrun shift.
Both the front and rear servos are dual area designs to allow accurate friction element matching without the need for
secondary regulator valves. All the friction elements have been designed to provide low shift energies and high static
capacities when used with the new low static co-efficient transmission fluids. Non-asbestos friction materials are used
throughout.
