1. Remove the filler plug (1).
2. Measure oil level to check if it is within the specification using a

suitable gauge (A) as shown.

CAUTION:

• Do not start engine while checking oil level.

• Insert the suitable gauge straight and against the wall of

the filler plug hole, then measure the gauge from the top

of the filler plug hole to the oil level as shown.

3. Install the filler plug with a new O-ring to the clutch housing.

CAUTION:

b. Set dial indicator as shown in the figure.

STEEL WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel

runout.

a. Remove tire from steel wheel and mount on a tire balance machine.

b. Set two dial indicators as shown in the figure.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around

the circumference of the wheel.

e. Calculate runout at each point as shown below.

f.

Select maximum positive runout value and the maximum nega-

tive value.

Add the two values to determine total runout.

In case a positive or negative value is not available, use the

maximum value (negative or positive) for total runout.

If the total runout value exceeds the limit, replace steel wheel.

• Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery

cable from the negative terminal.

1. Connect a vinyl tube to bleed valve.
2. Depress brake pedal, loosen bleed valve, and gradually remove

brake fluid.

REFILLING

CAUTION:

• Refill with new brake fluid “DOT 3”.

• Never reuse drained brake fluid.

• Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery

cable from the negative terminal.

1. Make sure there is no foreign material in the reservoir tank, and

refill with new brake fluid. 

2. Loosen bleed valve, depress brake pedal slowly to full stroke

and then release it. Repeat the procedure every 2 or 3 seconds

until the new brake fluid comes out, then close the bleed valve

while depressing the pedal. Repeat the same work for each

wheel.

VISUAL

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if necessary.

RUNOUT

1. Attach the disc rotor to wheel hub using wheel nuts at two or

more positions. 

2. Inspect runout using a dial gauge. Set the dial gauge to mea-

sure at 10 mm (0.39 in) inside the disc edge.

NOTE:

Before measuring, make sure that wheel bearing axial end play

is within the specification. Refer to 

FAX-6, "Inspection"

.

3. When runout exceeds limit value, displace mounting positions of

disc rotor by one hole. And then find a position of the minimum value for runout.

4. If runout is outside the specified value after performing the above operation, turn the disc rotor using Tool.

THICKNESS

Check thickness of the disc rotor using a micrometer. Replace disc

rotor if thickness is under the wear limit.
