5. Adjustment of Rear
Brake Lining
Clearance
The adjusting mechanism for the brake
lining clearance is of a manual type.
Follow the undermentioned proce-
dure.
1) Jack up vehicle body to release
wheel from the ground.
2)
Tighten the wedge fully until
wheel ceases to rotate. Screwing up
the wedge forces anchor to expand on
either side by the wedge action and
consequently shoes stick to drum.
3) Turn back the wedge for
180
0
,
and the shoe clearance will be
0.1
to
0.15
mm
(0.004
to
0.0059
in).
4) Be sure that tire and wheel can be
rotated easily by hand.

6. Wheel Cylinder
1) Disassembly
I)
Remove boot from cylinder.
2) Take out piston, which is piston
ASSY with cup.
NOTE:
a. Wheel cylinder can be disassembled
and inspected with it mounted on
the back plate. Therefore it should
not be removed except replacing
the wheel cylinder ASSV etc.
b. When removing the cup from pis-
ton, be careful not to damage
piston. And be sure to use the new
cup.
2) Inspection
Inspect each parts after washing them
with brake fluid, and replace if the
following defects are found.
NOTE:
Do not use any cleaning solvent other
than brake fluid.
1) Cup: Damage, fatigue or wear.
2) Cylinder and piston frictional
surfaces: damage, uneven wear, cor-
rosion or rust.
3) Assembly
Assembly is the reverse order of dis-
assembly.
NOTE:
a. When installing the cup, use the
special tool Adapter, apply brake
fluid to the frictional surface for
smooth installation and pay at·
tention to cup direction.
b. When replacing the repair kit, make
sure that the sizes of cylinder and
cup are the same as those which
were replaced.
