Before removing the steering wheel and air bag module assembly, always refer to GROUP 52B -
Service Precautions (P.52B-16), Air bag Module and Clock Spring (P.52B-237). Also, set the front
wheels so that they are facing straight forward, and remove the ignition key. If you fail to do this,
the SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious
injury.
*1: Indicates parts which should be initially tightened, and then fully tightened after placing the
vehicle horizontally and loading the full weight of the engine on the vehicle body.
*2: Indicates parts which should be temporarily tightened, and then fully tightened with the vehicle
on the ground in the unladen condition.

CLUTCH21A-3
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.

BASIC BRAKE SYSTEM DIAGNOSIS
BASIC BRAKE SYSTEM35A-4
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.

BLEEDINGM1351001400455
Use only brake fluid DOT 3 or DOT 4. Never mix the speci-
fied brake fluid with other fluid as it will influence the brak-
ing performance significantly.
.
MASTER CYLINDER BLEEDING
The master cylinder used has no check valve, so if bleeding is
carried out by the following procedure, bleeding of air from the
brake pipeline will become easier. (When brake fluid is not con-
tained in the master cylinder).
1. Fill the reserve tank with brake fluid.
2. Keep the brake pedal depressed.
3. Have another person cover the master cylinder outlet with a
finger.
4. With the outlet still closed, release the brake pedal.
5. Repeat steps 2
4 three or four times to fill the inside of the
master cylinder with brake fluid.
.
BRAKE LINE BLEEDING
Start the engine and bleed the air in the sequence shown in the
figure.
