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.

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.

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.

STEP 2. Check disc brake pistons for smooth
operation.
(1) With engine not running, depress the brake pedal
rapidly several times to deplete booster vacuum
reserves.
(2) Test each disc brake assembly one at a time.
a. Remove the lower caliper bolt, then remove
caliper from mount.
b. Have an assistant slowly depress the brake
pedal. Confirm piston(s) extend slowly and
smoothly with no jumpiness. Repeat for each
disc brake assembly.
Q: Do (does) the piston(s) move correctly?
YES :
Go to Step 3.
NO : Disassemble and inspect the brake
assembly (Front: refer to P.35A-33, Rear:
refer to P.35A-36). Then go to Step 5.
STEP 3. Check brake disc(s) for runout.
Refer to P.35A-19.
Q: Is runout outside of specifications?
YES :
Repair or replace the brake disc(s) as
necessary. Then go to Step 5.
NO : Go to Step 4.
STEP 4. Check brake discs for correct thickness.
Refer to P.35A-19.
Q: Is the thickness outside of specifications?
YES :
Repair or replace the brake disc(s) as
necessary. Then go to Step 5.
NO : Perform the brake line bleeding. Then go to
St e p 5.
STEP 5. Retest the system.
Q: Is the symptom eliminated?
YES :
The procedure is complete.
NO : Start over at Step 1. If a new symptom
appears, refer to the appropriate symptom
chart.
INSPECTION PROCEDURE 2: Insufficient Braking Power
.
DIAGNOSIS
STEP 1. Check that the specified brake fluid is
used, its level is correct, and no contamination is
found.
Q: Is there a fault?
YES :
Refill or replace with the specified brake
fluid DOT 3 or DOT 4. Bleed the brakes if
necessary (Refer to P.35A-16). Then go to
Step 7.
NO : Go to Step 2.
STEP 2. Check for spongy (not firm) brakes.
(1) With engine not running, depress the brake pedal
rapidly several times to deplete the booster
vacuum reserve.
(2) With the brake pedal fully released, depress the
brake pedal slowly until it stops.
(3) With a measuring device (ruler, etc.) next to the
brake pedal, depress the pedal firmly and
measure the distance the pedal traveled.
Q: Is the distance greater than 20 mm (0.8 inch)?
YES :
Bleed the brakes to remove air in the fluid
(Refer to P.35A-16). Then go to Step 7.
NO : Go to Step 3.
STEP 3. Check the brake booster function.
Refer to P.35A-14.
Q: Is there a fault?
YES :
Replace the brake booster. Then go to Step
7.
NO : Go to Step 4.

BASIC BRAKE SYSTEM35A-5
STEP 4. Check for pinched or restricted brake
tube or hose.
Q: Is there a pinched or restricted brake tube or hose?
YES :
Replace that complete section of brake tube
or brake hose. Then go to Step 7.
NO : Go to Step 5.
STEP 5. Check for oil, water, etc., on the pad
contact surfaces of all brakes.
Q: Is oil, water, etc., on the pad contact surface?
YES :
Replace the part and determine the
source/cause of foreign material. Recheck
symptom. Then go to Step 7.
NO : The procedure is complete. If condition
persists for vehicles without ABS, go to Step
6.
STEP 7. Recheck symptom.
Q: Is the symptom eliminated?
YES :
The procedure is complete.
NO : Start over at step 1. If a new symptom
surfaces, refer to the appropriate symptom
chart.
INSPECTION PROCEDURE 3: Increased Pedal Stroke (Reduced Pedal-to-Floor Board Clearance)
.
DIAGNOSIS
STEP 1. Check for spongy (not firm) brakes.
(1) With engine not running, depress the brake pedal
rapidly several times to deplete booster vacuum
reserve.
(2) With the brake pedal fully released, depress the
brake pedal slowly until it stops.
(3) With a measuring device (ruler, etc.) next to the
brake pedal, depress the pedal firmly and
measure the distance the pedal traveled.
Q: Is the distance greater than 20 mm (0.8 inch)?
YES :
Bleed the brakes to remove air in the fluid
(Refer to P.35A-16). Then go to Step 7.
NO : Go to Step 2.
STEP 2. Check the pad for wear.
Refer to P.35A-17.
Q: Is the pad thickness outside of specifications?
YES :
Replace the part. Then go to Step 7.
NO : Go to Step 3.
STEP 3. Check the vacuum hose and check valve
for damage.
Refer to P.35A-15.
Q: Is there a damage?
YES :
Replace the part. Then go to Step 7.
NO : Go to Step 4.
STEP 4. Check the master cylinder function.
Refer to P.35A-23.
Q: Is there a fault?
YES :
Repair it. Then go to Step 7.
NO : Go to Step 5.
STEP 5. Check for brake fluid leaks.
Q: Is there a leak?
YES :
Check the connection for looseness,
corrosion, etc. Clean and repair as
necessary. If leaking in any tube or hose
section, replace the complete tube or hose.
Then go to Step 7 .
NO : Go to Step 6.
STEP 6. Check for excessive clearance between
the push rod and primary piston.
Refer to P.35A-26.
Q: Is the clearance outside of specifications?
YES :
Adjust the clearance. Then go to Step 7.
NO : Go to Step 7.
STEP 7. Recheck symptom.
Q: Is the symptom eliminated?
YES :
The procedure is complete.
NO : Start over at step 1. If a new symptom
surfaces, refer to the symptom chart.
