CLUTCH PEDAL ADJUSTMENTNJCL0006S04Pedal StrokeNJCL0006S04011. Loosen the pedal stopper bolt completely (so there is no con-
tact between pedal and stopper bolt).
2. Adjust pedal stroke to the specified value with the master cyl-
inder push rod.
3. Adjust the pedal stopper bolt until it is just in contact with the
pedal, then tighten the lock nut.
4. Once stroke is set to specification, adjust clutch pedal free
play.
Pedal stroke “S”.
Refer to “SDS”, CL-24.
Pedal Free PlayNJCL0006S04021. Adjust pedal free play to the specified value with the master
cylinder push rod.
2. Tighten lock nut of the master cylinder push rod.
Push on the clutch pedal until resistance is felt, and check the
distance the pedal moves.
Pedal free play “A”.
Refer to “SDS”, CL-24.

AIR BLEEDING PROCEDURENJCL0006S021. Bleed air from clutch operating cylinder according to the fol-
lowing procedure.
Carefully monitor fluid level at master cylinder during
bleeding operation.
a. Top up reservoir with recommended brake fluid.
b. Connect a transparent vinyl tube to air bleeder valve.
c. Slowly depress the clutch pedal to its full stroke and release it
completely. Repeat this operation several times at 2 to 3 sec-
onds intervals.
d. Open the air bleeder with the clutch pedal fully depressed.
e. Close the air bleeder.
f. Release the clutch pedal and wait at least 5 seconds.
g. Repeat steps c through f mentioned above, then air bubbles
will no longer appear at the damper in the brake fluid.
Air bleeder valve tightening torque:
: 5.9 - 9.8 N·m (0.6 - 1.0 kg-m, 52 - 86 in-lb)

RemovalNJCL00081. Drain brake fluid.
CAUTION:
Be careful not to splash brake fluid on painted areas; it may
cause paint damage. If brake fluid is splashed on painted
areas, wash it away with water immediately.
2. Remove clutch tube using a flare nut wrench.
3. Remove snap pin between clutch pedal and push rod, and
remove clevis pin.
4. Unscrew master cylinder assembly mounting nuts and remove
master cylinder assembly from vehicle.
InstallationNJCL00091. Connect clutch tube to master cylinder assembly, and hand-
tighten flare nut.
2. Install master cylinder assembly to vehicle, and tighten mount-
ing nuts to the specified torque.
: 11 - 14 N·m (1.1 - 1.5 kg-m, 8 - 10 ft-lb)
3. Tighten clutch tube flare nut using a flare nut torque wrench.
: 15 - 18 N·m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)
4. After installing clevis pin, install snap pin to connect clutch
pedal to push rod.
5. After finishing the operation, bleed air from clutch piping con-
nector and operating cylinder. (Refer to “Air Bleeding
Procedure”, CL-10.)
SCL725
DisassemblyNJCL00101. Loosen push rod lock nut A to remove clevis and lock nut A.
2. Remove dust cover.
3. Remove stopper ring and stopper, and remove push rod from
cylinder body. During removal, keep push rod depressed, to
prevent piston inside master cylinder from popping out.
4. Remove piston assembly from cylinder body.
InspectionNJCL0011Check the following items, and replace if necessary.
Rubbing surface of cylinder and piston, for uneven wear, rust
or damage
Piston with piston cup, for wear or damage
Return spring, for wear or damage
Dust cover, for cracks, deformation or damage
Reservoir, for deformation or damage

Checking Brake Fluid LevelNJBR0006Check fluid level in reservoir tank. It should be between Max
and Min lines on reservoir tank.
If fluid level is extremely low, check brake system for leaks.
Release parking brake lever and see if brake warning lamp
goes off. If not, check brake system for leaks.
SBR389C
Checking Brake LineNJBR0007CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
SBR419C
Changing Brake FluidNJBR0008CAUTION:
Refill with new brake fluid “DOT 4”.
Always keep fluid level higher than minimum line on res-
ervoir tank.
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing
brake pedal while keeping reservoir level higher than minimum
line by adding new brake fluid.
4. Repeat until new brake fluid comes out of each air bleeder
valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to “Bleeding Brake System”, BR-8.
Brake Burnishing ProcedureNJBR0036Burnish the brake contact surfaces according to the following pro-
cedure after refinishing or replacing drums or rotors, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31
MPH).
2. Use medium brake pedal/foot effort to bring the vehicle to a
complete stop from 50 km/h (31 MPH). Adjust brake pedal/foot
