REMOVAL
CAUTION:
lDo not allow brake fluid to spill or splash on painted surfaces. Brake fluid can seriously damage
paint. If it gets on a painted surface, wipe it off immediately and wash with water.
lDo not bend or twist the brake hose sharply, or strongly pull it.
lCover brake fluid line connections to prevent dust and other foreign material from entering.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel while depressing the brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from the brake hose.
4. Remove union bolts and disconnect caliper assembly from the
brake hose.
5. First remove lock spring from brake tube and strut mounting
positions. Then remove brake hose.

InspectionEFS000C9
CAUTION:
If any connection leaks, retighten it. Replace any damaged parts.
1. Check hose, tube, and connections for fluid leaks, damage, twist, deformation, contact with other parts,
and loose connections.
2. Run the engine. Depress brake pedal and hold it for approximately 5 seconds while checking each part
for leaks.:15-17N·m(1.5-1.8kg·m,11-13ft·lb)

WA RN ING:
lClean dust on brake caliper and pad with a vacuum dust collector. Do not blow with compressed
air.
CAUTION:
lNever depress brake pedal while removing cylinder body because the piston will pop out.
lDo not remove brake hose and torque member mounting bolts unless disassembling or replacing
caliper assembly. Hang the cylinder body with a wire so that the brake hose is not under tension.
lBe careful not to damage the piston boot. Do not allow brake fluid to get on the rotor.
lWhen replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.

PAD WEAR INSPECTION
Check pad thickness by lifting vehicle, removing the wheel, and
looking through check hole on cylinder body.If necessary, use a
scale.

CAUTION:
lBe careful not to damage sensor edge and rotor tooth. Before removing front or rear wheel hub,
remove wheel speed sensor to avoid sensor wiring damage. Otherwise, sensor may be deacti-
vated.
lWhen removing sensor, avoid rotating it as much as possible. Do not forcibly pull sensor harness.
lWhen installing, check sensor pick-up and mounting hole for foreign material such as iron chips.
Check no foreign material has been caught in sensor rotor. Remove any foreign material found.
Tighten mounting bolts and nuts to the specified torque.

CAUTION:
Be careful not to bring any grease into contact with the clutch disk facing, pressure plate surface, or
flywheel surface.
REMOBAL
1. Remove manual transaxle from the vehicle. Refer toMT-16, "Removal and Installation"
2. Loosen clutch cover mounting bolts evenly. Remove clutch cover and clutch disk.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch disk
lMeasure circumferential runout relative to the clutch disk center
spline. If it is outside the specification, replace the clutch disk.
lMeasure clutch disk spline and input shaft spline backlash at the
circumference of the disk. If outside the specification, replace.
lUsing calipers, measure the depth to the clutch disk facing rivet
heads. If it exceeds the allowable wear limit, replace the facing.
SCIA0329E
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:

CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
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).
lCheck clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:
lWorn thrust ring will generate a beating noise when tapped at
therivetwithahammer.
lBroken thrust ring will make a clinking sound when cover is
shaken up and down.
lIf a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disk 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).
INSTALLATION
1. Apply recommended Grease to clutch disk and input shaft splines.
CAUTION:
Be sure to apply grease to the points specified. Otherwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause slip or judder. Wipe off any grease oozing
from the parts.
2. Install clutch disk and clutch cover. Pre-tighten mounting bolts
and install clutch aligning bar.
3. Tighten clutch cover attaching bolts evenly in two steps in the
order shown in the figure.
4. Install manual transaxle. Refer toMT-16, "
Removal and Installation"
