H
2 when clutch is disengaged are within the specified ranges below.
5. Check that free play A at pedal pad top surface and pedal height
H
2 when clutch is disengaged are within the specified ranges
below. If it is outside the specification, loosen lock nut A and turn
push rod to adjust.

CLUTCH MASTER CYLINDER
REMOVAL
1. Using one of the following methods, remove hose from the nipple.
●Drain clutch fluid from reservoir tank and remove hose.
●Remove hose from the nipple. Immediately plug hose and reservoir tank to prevent clutch fluid from
dripping.
CAUTION:
Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the
affected area with water.
2. Using a flare nut wrench, remove clutch tube.
3. Remove snap pin and clevis pin on clevis in passenger compartment to separate clutch pedal.
4. First remove the mounting nuts on the master cylinder assembly, and then the master cylinder assembly
from the vehicle.
INSTALLATION
1. Connect clutch tube to master cylinder assembly and temporarily tighten flare nut.
2. Install master cylinder assembly and tighten mounting nut to the specified torque.
3. Using a flare nut torque wrench, tighten clutch tube flare nut to the specified torque.
4. Attach clevis of the clevis pin to the clutch pedal.
5. Attach snap pin to the clevis pin.
6. Install hose to the nipple.
7. After completing this procedure, inspect and adjust pedal height and then bleed the clutch tube.
●Refer to CL-5, "On-Vehicle Inspection and Adjustment" , CL-8, "Air Bleeding Procedure" .
Disassembly and AssemblyECS008BB
DISASSEMBLY
1. Using a pin punch, remove spring pin, nipple and seal from the
cylinder body.
2. Loosen push rod lock nut. Remove clevis and lock nut.
3. Remove seat.
4. Remove stopper ring and stopper. Remove push rod from cylin-
der body while holding it securely to reduce possibility of the pis-
ton popping out.
5. Remove piston assembly and return spring.
INSPECTION AFTER DISASSEMBLY
Check for any of the conditions shown below. If any malfunction is found, replace the part concerned.
●Damaged cylinder internal wall, foreign matter, wear, corrosion, or pinhole
●Damaged or deformed nipple or reservoir tank
●Settling of the spring
●Cracked or deformed seat
ASSEMBLY
1. Apply rubber lubricant to internal surface of the cylinder body, sliding surface of piston assembly, and the
piston cup. Insert piston assembly and return spring.
2. Apply silicon grease to push rod and install stopper. Install stopper ring while holding down the push rod
by hand to prevent the piston assembly from popping out.
3. Install seat.
4. Install clevis to the push rod and tighten lock nut to the specified torque.
5. Install seal and nipple to the cylinder body. Using a pin punch, install spring pin.

CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc
●Measure circumferential runout relative to the clutch disc center
spline. If it is outside the specification, replace the clutch disc.
●Measure clutch disc spline and input shaft spline backlash at the
circumference of the disc. If outside the specification, replace.
●Using calipers, measure the depth to the clutch disc facing rivet
heads. If it exceeds the allowable wear limit, replace the clutch
disc.
Clutch Cover
Check diaphragm spring lever claws for unevenness with the lever
still on the vehicle. If they exceed the tolerance, adjust lever height
using a diaphragm adjusting wrench (special service tool).
●Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:
●Worn thrust ring will generate a beating noise when tapped at
the rivet with a hammer.
●Broken thrust ring will make a clinking sound when cover is
shaken up and down.
●If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace the assembly.
Flywheel Runout
Using a dial gauge, measure runout at the flywheel clutch contact
surface. If runout is outside the specification, replace the flywheel. If
a trace of burn or discoloration is found on the surface, repair it with
sandpaper.
CAUTION:
Measure it at flywheel outer face (not on knock pin and clutch cover mounting hole). Runout limit/diameter of the area to be measured:
1.0 mm (0.039 in) or less/230 mm(9.06 in) dia.
Maximum allowable spline backlash:
1.0 mm (0.039 in)

On-Vehicle Inspection and AdjustmentEFS000C1
Adjust clearance between dash panel and brake pedal upper surface
to the following dimensions.
1. Loosen stop lamp switch by rotating it counter-clockwise by 45°.
2. Loosen input rod lock nut (A), then rotate input rod, set pedal to
the specified height, and tighten lock nut (A).
CAUTION:
Confirm threaded end of input rod remains inside the cle-
vis.
3. Pull pedal by hand and hold it. Press stop lamp switch until its
threaded end contacts the stopper rubber.
4. While holding it against the stopper rubber, turn the switch clock-
wise by 45° and secure it.
CAUTION:
Be sure stopper rubber to stop lamp switch screw threaded
end gap (C) is within specifications.
5. Check pedal free play.
CAUTION:
Be sure stop lamps go off when pedal is released.
6. Start the engine and check brake pedal depressed height.
