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.
INSTALLATION
CAUTION:
lRefill with new brake fluid “DOT 3” or “DOT4”.
lNever reuse drained brake fluid.
1. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.

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 brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:
lWhen cylinder body is open, do not depress brake pedal because piston will pop out.
lBe careful not to damage piston boot or get oil on rotor. Always replace shims when replacing
pads.
lIf shims are rusted or show peeling of the rubber coat, replace them with new shims.
lIt is not necessary to remove connecting bolt except for disassembly or replacement of caliper
assembly. In this case, suspend cylinder body with wire so as not to stretch brake hose.
lBurnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing
pads or linings, or if a soft pedal occurs at very low mileage. Refer toBR-10, "
Brake Burnishing
Procedure".

INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
lCheck cylinder inner wall for corrosion, wear and damage. If corrosion, wear or damage is detected,
replace the cylinder body.
lMinor flaws caused by corrosion or foreign material can be removed by polishing the surface with fine
sandpaper. Replace the cylinder body, if necessary.
Torque Member
Check for wear, cracks and damage. If wear, cracks or damage is detected, replace the applicable part.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear and damage. If corrosion, wear or damage is detected, replace the
applicable part.
Sliding Pin, Pin Bolt, and Pin Boot
Check sliding pin and sliding pin boot for wear, damage and cracks. If corrosion, wear or damage is detected,
replace the applicable part.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of the disc rotor for uneven wear, cracks and serious damage. If uneven wear, cracks or seri-
ous damage is detected, replace it.
Run Out Inspection
1. Using wheel nuts, fix the disc rotor to the wheels hub. (2 or more positions)
2. Using a dial indicator, check run out.
CAUTION:
Before measuring, make sure that the axle endplay is 0 mm
(0 in).
3. If the run out is outside the limit, find the minimum run out point
by shifting the mounting positions of the disc rotor and wheel hub by one hole.

Measurement point:
At a point 10 mm (0.39 in) from the outer edge of the
disc.

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, "
