REMOVAL
1) Perform steps 1) to 5) of BRAKE DRUM REMOVAL.
2) Perform steps 2) to 4) of BRAKE SHOE REMOVAL.
3) Loosen brake pipe flare nut (or nuts) but only within the extent
that fluid does not leak.
4) Remove wheel cylinder mounting bolts. Disconnect brake pipe
(or pipes) from wheel cylinder and put wheel cylinder bleeder
plug cap onto pipe to prevent fluid from spilling.
INSPECTION

sion or damage.
NOTE:
Clean wheel cylinder components with brake fluid.
INSTALLATION (For non sealed type)
1) Take off bleeder plug cap from brake pipe and connect pipe (or
pipes) to wheel cylinder just enough to prevent fluid from leak-
ing.
2) Tighten wheel cylinder to brake back plate to specified torque.

NOTE:

For air bleeding of master cylinder alone, it must be removed
from vehicle.
(For procedures of removal and installation of master cylin-
der assembly and air bleeding, refer to CLUTCH MASTER

INSTALLATION
1) To bleed air from master cylinder itself, tilt it as shown in figure
and add fluid into it.
NOTE:
After bleeding air from master cylinder, plug pipe hole in it
to prevent fluid from spilling out of it till pipe is connected.
2) Install master cylinder assembly and new gasket to body, attach-
ing bolt, nuts and push rod clevis pin.
NOTE:
Do not reuse gasket.
3) Torque attaching bolt and nut to specification.
4) Connect fluid pipe and torque flare nut to specification.

5) Apply grease to clevis pin and install it.
ªAº: Grease 99000-25010
6) Fill reservoir with specified brake fluid and check fluid leakage.
7) After installation, bleed air from system and check clutch pedal
free travel. Refer to BRAKE section for air bleeding procedure.
FLUID INSPECTION
Fluid level should be always between MIN and MAX lines on reser-
voir. If fluid decreases quickly, check for leakage, repair leaky point,
if any, and add fluid up to MAX level.
NOTE:

Brake fluid damages painted surface badly. Should it get on
painted surface, remove it immediately and clean surface
thoroughly.

Do not use shock absorber fluid or any other fluid which con-
tains mineral oil. Do not use container which has been used
for mineral oil or which is wet from water. Mineral oil will
cause swelling and distortion of rubber parts in hydraulic
clutch system and water will mix with brake fluid, lowering
fluid boiling point. Keep all fluid containers capped to pre-
vent contamination.

Make sure not to use fluid whose container cap was first
opened more than a year ago.
