REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove caliper pin bolts.
3) Remove E-ring from strut and then remove caliper from caliper
carrier.
NOTE:
Hang removed caliper with a wire hook or the like so as to
prevent brake hose from bending and twisting excessively
or being pulled. Don't operate brake pedal with pads re-
moved.
4) Remove pads.
INSPECTION
Brake Pad
Check pad lining for wear. When wear exceeds limit, replace with
new one.
CAUTION:
Never polish pad lining with sandpaper. If lining is polished
with sandpaper, hard particles of sandpaper will be depos-
ited in lining and may damage disc. When pad lining re-
quires correction, replace it with a new one.
Pad thickness (lining + rim) ªaº
Standard: 15.0 mm (0.590 in.) For SUMITOMO ELECTRIC. . .
brake calliper
15.5 mm (0.610 in.) For TOKICO brake caliper. . .
Service limit: 7.0 mm (0.275 in.) For SUMITOMO ELECTRIC. .
brake caliper
7.5 mm (0.295 in.) For TOKICO brake caliper. .
NOTE:
When pads are removed, visually inspect caliper for brake
fluid leak. Correct leaky point, if any.

REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove brake flexible hose mounting bolt from caliper. As this
will allow fluid to flow out of hose, have a container ready before-
hand.
3) Remove caliper pin bolts.
4) Remove caliper.
DISASSEMBLY
Before disassembly, clean all around caliper with brake fluid.
1) Remove anti noise shim (if equipped) and blow compressed air
into cylinder through bolt hole where flexible hose was fitted.
With this air pressure, piston can be pushed out of cylinder.
WARNING:
Do not apply too highly compressed air which will cause
piston to jump out of cylinder. It should be taken out grad-
ually with moderately compressed air. Do not place your
fingers in front of piston when using compressed air.

2) Remove piston seal using a thin blade like a thickness gauge,
etc.
CAUTION:
Be careful not to damage inside (bore side) of cylinder.
INSPECTION
Cylinder Boot
Check boots for breakage, crack and damage. If defective, replace.
Piston Seal
Excessive or uneven wear of pad lining may indicate unsmooth re-
turn of the piston. In such a case, replace rubber seal.
ASSEMBLY
Reassemble front brake in reverse order of disassembly, noting the
following points.
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 and piston seal to cylinder, apply
fluid to them.

After reassembling brake lines, bleed air from them.
Piston Seal
Piston seal is used to seal piston and cylinder and to adjust clear-
ance between pad and disc. Replace with a new one at every over-
haul. Fit piston seal into groove in cylinder taking care not to twist
it.

Caliper
Before installing caliper (cylinder body) to carrier, check to ensure
that guide pin (pin bolt) inserted in each caliper carrier hole can be
moved smoothly in thrust direction.
NOTE:
Where temperature gets as low as ±30
C in cold weather, use
rubber grease whose viscosity varies very little even at ±40
C
(±40
F).
INSTALLATION
1) Install caliper to caliper carrier.
2) Torque caliper pin bolts to specifications.

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 re-
surface drum braking surface.
If brake linings are slightly worn and drum is grooved, drum should
be polished with fine emery cloth but should no be turned.
NOTE:
When drum is removed, visually inspect wheel cylinder for
brake fluid leakage. Correct leaky point, if any.
Brake Shoe
Where lining is worn out beyond service limit, replace shoe.
Thickness ªaº
Standard: 6.5 mm (0.24 in.)
Service limit: 3.0 mm (0.12 in.)
If one of brake linings is to service limit, all linings must be replaced
at the same time.
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.
INSTALLATION
NOTE:
See NOTE at the beginning of the section.
1) Before installing brake drum, check outer diameter of brake
shoes. If it is not within value as specified below, adjust it to spec-
ification by turning adjuster.
Outer diameter of brake shoes
ªaº: 219.4 ± 219.7 mm (8.638 ± 8.650 in.)

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
Inspect wheel cylinder disassembled parts for wear, cracks, corro-
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.
