Disassembly
CAUTION!
Clean around caliper with brake fluid before
disassembly.

1) Remove disc brake piston with air blown into flexible
hose joint bolt installation hole.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth (1) to prevent piston
from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.

2) Remove cylinder boot.
3) Remove piston seal using a thin blade like a
thickness gauge, etc.
CAUTION!
Be careful not to damage inside (bore side) of
cylinder.

Assembly
Assemble parts in reverse order of disassembly,
observing the following instructions.
CAUTION!
• Wash each part cleanly before installation
in the same fluid as the one used in master
cylinder reservoir.
• Never use other fluid or thinner.
• Before installing piston seal and cylinder
boot to cylinder, apply rubber grease
included in piston seal set or brake fluid to
them.
• Install a new piston seal into groove in
cylinder securely making sure that it is not
twisted.
• After reassembling brake lines, bleed air
from them.

Before installing caliper to carrier, install slide pins with
rubber grease included in slide pin / boot set applied into
caliper carrier hole and check for its smooth movement
in thrust direction.
• Install piston seal, boot and piston to caliper referring
to the following instructions.
1) Replace with a new piston seal (1) at every overhaul.
After applying rubber grease included in piston seal
set or brake fluid, fit piston seal (1) into groove in
cylinder taking care not to twist it.2) Before inserting piston (1) into cylinder, apply rubber
grease included in piston seal set or brake fluid to
new boot (a) and install it onto piston as shown.
3) Fit boot as it is in figure into boot groove in cylinder
with fingers.
4) Insert piston into cylinder by hand and fit boot in boot
groove in piston.
NOTE
Check that boot is fitted in boot groove
securely all around piston and cylinder.

5) To confirm that boot is fitted in its groove in cylinder
properly, pull piston out of cylinder a little but do not
take it all out.
NOTE
Boot’s face (1) should be at the same level
from cylinder’s face (2) all around.

Rear Brake Drum Removal and InstallationS6RW0D4306002
Removal
1) Hoist vehicle and remove rear wheel.
2) Release parking brake lever.
3) Remove brake drum (1) by using 8 mm bolts (2) (2
pcs).
Installation
1) Before installing brake drum, to maximize brake
shoe-to-drum clearance, put screwdriver between
rod and ratchet and push down ratchet.
NOTE
The figure show ratchet position where brake
shoe-to-drum clearance is maximum.

2) Confirm that inside of brake drum and brake shoes
are free from dirt and oil. And then install brake
drum.
3) Start engine and then depress brake pedal with
about 300 N (30 kg, 66 lbs) load at least 3 times until
adjuster actuator clicking sound from drum brake
can not be heard so as to obtain proper drum-to-
shoe clearance.
Adjust parking brake cable referring to “Parking
Brake Inspection and Adjustment in Section 4D”.
4) Install rear wheel.
5) Check to ensure that brake drum is free from
dragging and proper braking is obtained. Perform
brake test (foot brake and parking brake).
Rear Brake Drum and Shoe InspectionS6RW0D4306003
Brake Drum
Inspect brake drum for wear.
If drum inner diameter is exceeds the limit or uneven or
stepped wear is excessive, replace the drum.

Cracked, Scored or Grooved Drum
A cracked drum is unsafe for further service and must be
replaced. Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring
will cause excessive brake lining wear and it will
probably be necessary to resurface drum braking
surface.
If brake linings are slightly worn and drum is grooved,
drum should be polished with fine emery cloth in the
direction of drum depth but not circumferentially along
drum inner.
NOTE
When drum is removed, visually inspect
wheel cylinder for brake fluid leakage.
Correct leaky point, if any.

Brake Shoe
Measure thickness of brake shoe (1). Also, check
surface of lining for hardening, excessive wear and oil.
Rear brake shoe lining thickness
“a”
Standard: 4.0 mm (0.157 in.)
Limit: 1.0 mm (0.04 in.)
CAUTION!
Never polish lining with sandpaper. If lining is
polished with sandpaper, hard particles of
sandpaper will be deposited in lining and
may damage drum. When it is required to
correct lining, replace it with a new one.

Rear Brake Shoe On-Vehicle InspectionS6RW0D4306004
Amount of brake shoe wear can be checked as follows.
1) Hoist vehicle.
2) Remove rubber cover (plug) (1) from brake back
plate.
3) Through hole of back plate, visually check for
thickness of brake shoe lining (2). If lining thickness
is less than specified wear limit, replace all brake
shoes with new ones.
Lining thickness “a”
Service limit: 1.0 mm (0.04 in.)
Rear Brake Shoe Removal and InstallationS6RW0D4306005
NOTE
When replacing brake shoe, replace it on the
