2. Measure the clutch pedal height.
Standard value (A): 163.5 – 166.5 mm

4. Measure the clutch pedal play.
Standard value (B): 1 – 3 mm
5. If the clutch pedal play is not within the standard value,
loosen the setting nut and move the push rod to adjust.
Caution
Do not push in the master cylinder push rod at this
time.
6. After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of
the pedal pad) and the toeboard when the clutch is
disengaged are within the standard value ranges.
Standard value (C): 6–13 mm
Standard value (D): 85 mm or more
7. If the clutch pedal free play and the distance between
the clutch pedal and the toeboard when the clutch is
disengaged do not agree with the standard values, it
is probably the result of either air in the hydraulic system
or a faulty master cylinder or clutch. Bleed the air, or
disassembly and inspect the master cylinder or clutch.
8. Turn back the carpet, etc.
BLEEDING
Specified fluid: Brake fluid DOT 3 or DOT 4
Caution
Use the specified brake fluid. Avoid using a mixture of
the specified fluid and other fluid.

TORQUE CHECK
(1) After shaking the ball joint stud several times, install the
nut to the stud and use the special tool to measure the
rotation starting torque of the ball joint.
Standard value: 1.0 – 3.4 Nm
(2) When the measured value exceeds the standard value,
replace the ball joint assembly.
(3) When the measured value is lower than the standard
value, check that the ball joint turns smoothly without
excessive play. If so, it is possible to use that ball joint.
LOWER ARM BALL JOINT DUST COVER
REPLACEMENT
When the dust cover is damaged during service work or grease
leaks out from the dust cover, replace the dust cover in the
