GENERAL INFORMATION
M1211000100234
The clutch is a dry single-disc, diaphragm type;
hydraulic pressure is used for the clutch control. The
clutch shares a brake fluid reservoir with the brake
system.

1. Turn up the carpet, etc. under the clutch pedal.2. Measure the clutch pedal height.
Standard value (A): 183
186 mm
3. Measure the clutch pedal clevis pin play.
Standard value (B): 1

ON-VEHICLE SERVICE

Do not push in the master cylinder pushrod at
this time, otherwise the clutch will not operate
properly.
4. If the clutch pedal height and clutch pedal clevis
pin play are not within the standard value, loosen
the setting nut to adjust the clutch pedal height
and clevis pin play to the standard value.
5. Check the clutch pedal switch clearance is within
specification when pedal height is adjusted
correctly and is positioned at rest. If adjustment is
required, loosen nut and rotate switch to achieve
correct clearance.
Switch clearance value (C): 0.5
1.5 mm
Nut tightening torque : 10 - 15 Nm6. After completing the adjustments, confirm that the
clutch pedal free play clearance (measured
between pedal switch and bracket) and the
distance between the clutch pedal (the face of the
pedal pad) and the clutch pedal stopper when the
clutch is disengaged are within the standard value
ranges.
Standard value (C): 0.5
1.5 mm
Standard value (D): 35 mm or more
7. If the clutch pedal free play and the distance
between the clutch pedal and the clutch pedal
stopper or 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,
release cylinder or clutch. Bleed the air, or
disassemble and inspect the master cylinder,
release cylinder or clutch.
CLUTCH BLEEDINGM1211001400205
Use the specified brake fluid. Do not mix brake
fluids.
Specified fluid: Brake fluid DOT 3 or DOT 4
1. Connect a hose with a bottle to the bleeder screw.
2. Open the bleed nipple.
3. Depress the clutch pedal slowly. Open the bleeder
screw to let air and brake fluid out. Close the
bleeder screw. Release the clutch pedal. Repeat
until only brake fluid and no air comes out.
4. Check that the brake fluid reservoir level stays
between "MAX" and "MIN" marks throughout the
clutch bleeding process.

Holding the nut at the clutch hose side, loosen the
flare nut of the clutch pipe.

INSTALLATION
1. Temporarily tighten the clutch pipe flare nut by
hand, and then tighten it to the specified torque,
being careful that the clutch hose does not become
twisted.
2. After tightening the clutch pipe flare nut and eye
bolt, check to be sure there is no clutch fluid leak
INSPECTION
M1211002000158
Check the master cylinder or clutch hose for fluid
leakage.
Check the clutch hose or tube for cracks or
clogging.
Check the pedal shaft bushing for wear.
Check the pedal arm for bend or torsion.

GENERAL DESCRIPTION
BASIC BRAKE SYSTEM35A-2
GENERAL DESCRIPTIONM1351000100440
The brake system has been designed to give greater
reliability and durability and to provide excellent brak-
ing performance.
FEATURES
.
Improved braking performance
1. An 8+9 inch tandem brake booster provides suffi-
cient braking force in sudden braking range.
2. 296mm front ventilated disc brakes provide sta-
ble braking force and improved braking feel.
3. 303mm rear ventillated disc brakes are used.
.
Improved stability
1. A 4-wheel anti-lock braking system (4ABS) pre-
vents slipping caused by the vehicle wheels lock-
ing up, in order to maintain a stable vehicle
posture and steering performance.
2. An electronic brake-force distribution (EBD)
makes it possible to maintain the maximum
amount of braking force even when the vehicle's
load is unevenly distributed. 3. Front- and rear-wheel X-type brake line layout
are used.
4. Ventilated discs brakes improve anti-fading per-
formance.
.
Improved serviceability
1. A diagnosis function for the ABS system makes
inspection easier.
2. An outer disc separated hub and rotor make
removal and installation easier.
3. The master cylinder reservoir is utilised for both
brake and clutch fluid on manual transmission
vehicles.
4. The master cylinder filter is coloured black for
improved viewing.
5. The ABS-ECU and hydraulic unit are integrated
to make them more compact and light weight.
