3. Shorten adjuster by rotating it.
+To tighten loosened brake shoes, first, insert a screw driver in
the direction shown in the left. Then, move the adjuster in the
direction shown by the arrow while disengaging the tooth con-
tact. Never tap the area E.

5. Install all parts.
Be careful not to damage wheel cylinder piston boots.
6. Check all parts are installed properly.
Pay attention to direction of adjuster assembly.
7. Install brake drum.
8. When installing new wheel cylinder or overhauling wheel
cylinder, bleed air. Refer to ªBleeding Brake Systemº, BR-8.
9. Adjust parking brake. Refer to BR-48.

CAUTION:
+When cylinder body is open, do not depress brake pedal
because piston will pop out.
+Be careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
+If shims are rusted or show peeling of rubber coat, replace
them with new shims.

+It 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
