Brake pad
REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove caliper pin bolts (2).
3) Remove caliper (1) from caliper carrier.
4) Remove pads (3).
INSPECTION
Check pad lining for wear. When wear exceeds limit, replace with
new one.
Brake pad thickness (lining + pad rim)
Standard : 15 mm (0.59 in.)
Limit : 7 mm (0.28 in.)
1. Caliper
3. Disc
NOTE:
Hang removed caliper (1) with a wire hook (2) or the like
so as to prevent brake hose from bending and twisting
excessively or being pulled.
Don’t operate brake pedal with pads (3) removed.
CAUTION:
Never polish pad lining with sandpaper. If lining is pol-
ished with sandpaper, hard particles of sandpaper will be
deposited in lining and may damage disc. When pad lin-
ing requires correction, replace it with a new one.
NOTE:
When pads are removed, visually inspect caliper for
brake fluid leak. Correct leaky point, if any.

INSPECTION
Cylinder Slide Bush
Check slide bush for smooth movement as shown.
If it is found faulty, correct or replace. Apply rubber grease to bush
outer surface. Rubber grease should be the one whose viscosity
is less affected by such low temperature as – 40 °C (– 40 °F).
Bush Dust Boot and Cylinder Boot
Check boots for breakage, crack and damage. If defective,
replace.
Piston Seal
Excessive or uneven wear of pad lining may indicate unsmooth
return of the piston. In such a case, replace rubber seal.
1. Apply rubber grease

ASSEMBLY
1) Check that slide bushes and boots for wear, corrosion, dam-
age, movement or deterioration. If it is found faulty, correct or
replace.
Apply rubber grease to bush outer surface. And then make
sure that each bush slides easily through each caliper bolt
hole.
2) Tighten bleeder plug to specified torque and install cap.
Tightening torque
Front caliper bleeder plug
(a) : 11 N·m (1.1 g-m, 8.0 lb-ft)
3) Piston seal is used to seal piston and cylinder and to adjust
clearance between pad and disc. Replace with a new one at
every overhaul. Fit piston seal into groove in cylinder taking
care not to twist it.
4) Before inserting piston (2) into cylinder, install new boot (1)
onto piston (2) as shown.
“A” : 2-grooved side directed inside
“B” : 3-grooved side directed outside 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.
NOTE:
Where temperature gets as low as – 30 °C (– 22 °F) in cold
weather, use rubber grease whose viscosity varies very
little even at – 40 °C (– 40 °F).

3) Install brake flexible hose (4) as shown and torque hose
mounting bolt (3) to specification.
Tightening torque
Front brake flexible hose bolt
(a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
4) Install wheel and torque wheel nuts to specification.
5) After completing installation, fill reservoir with brake fluid and
bleed brake system. Perform brake test and check each
installed part for oil leakage.
Brake Disc
REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove caliper assembly by loosening carrier bolts (2 pcs).
3) Pull brake disc off by using 8 mm bolts (1) (2 pcs).
1. Brake caliper
2. Washer
CAUTION:
During removal, be careful not to damage brake flexible
hose and not to depress brake pedal.

INSPECTION
Check disc surface for scratches in wearing parts. Scratches on
disc surface noticed at the time of specified inspection or replace-
ment are normal and disc is not defective unless they are serious.
But when there are deep scratches or scratches all over disc sur-
face, replace it. When only one side is scratched, polish and cor-
rect that side.
Brake disc thickness “a”
Standard : 10 mm (0.394 in.)
Limit : 8.0 mm (0.315 in.)
Use wheel nuts (1) and suitable plain washers (2) to hold the disc
securely against the hub, then mount a dial indicator as shown
and measure the runout at 10 mm (0.39 in.) from the outer edge
of the disc.
Disk deflection
Limit : 0.15 mm (0.006 in.)
INSTALLATION
1) Install disc to wheel hub.
2) Install caliper assembly to steering knuckle.
3) Torque caliper carrier bolts to specification.
Tightening torque
Brake caliper carrier bolts
(a) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
4) Install wheel and torque front wheel nuts to specification.
5) Upon completion of installation, perform brake test.
NOTE:
Check front wheel bearing for looseness before measure-
ment.
NOTE:
See NOTE at the beginning of this section.

CHECK FOR FRONT BRAKE AFTER INSTALLATION
Mount tires and make certain that they rotate smoothly, with a
force of less than 3.0 kg (6.6 Ib).
If tire rotation is heavy, check the following:
Piston, piston seal and cylinder slide bush of caliper for
installation.
Wheel bearings for breakage.
Disc for flatness (Improper flatness brings disc into contact
with lining during rotation and makes rotation heavy).
To check this, measure disc deflection.NOTE:
For above check the following must be observed.
Jack up front wheels, both right and left, off the
ground.
Shift transfer shift lever to 2H (rear wheel) position (if
equipped) and start engine for a few seconds then
stop.
Side figure shows outer periphery of tire.
Be careful not to depress brake pedal when checking
tire for rotation.

5) To increase clearance between brake shoe and brake drum,
remove rubber plug from brake back plate and turn adjuster
downward with flat-head screw driver.
6) Remove brake drum (1) off by using 8 mm bolts (2).
INSPECTION
Brake Drum
Inspect drum for cleanliness. Check wear of its braking surface by
measuring its inside diameter.
Drum inner diameter “a”
Standard : 220 mm (8.66 in.)
Service Limit : 222 mm (8.74 in.)
Whenever brake drums are removed, they should be thoroughly
cleaned and inspected for cracks, scores, deep grooves.
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 neces-
sary to resurface drum braking surface.
If brake linings are slightly worn and drum is grooved, drum
should be polished with fine emery cloth but should not 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.
If one of brake linings is to service limit, all linings must be
replaced at the same time.
Brake shoe thickness (lining + shoe rim) “a”
Standard (lining + rim) : 6.5 mm (0.26 in.)
Service limit : 3.0 mm (0.12 in.)
INSTALLATION
1) Before installing brake drum, check outer diameter of brake
shoes. If it is not within value as specified below, adjust it to
specification by turning adjuster (1).
Outer diameter of brake shoes
“a” : 219.4 - 219.7 mm (8.638 - 8.650 in.)
2) Install brake drum after making sure that inside of brake
drum and brake shoes are free from dirt and oil.
3) Upon completion of all jobs, depress brake pedal with about
30 kg (66 lbs) load about 30 times so as to obtain proper
drum-to-shoe clearance.
Adjust parking brake cable.
4) Install wheel and tighten wheel nuts to specified torque.
Tightening torque
Wheel nuts
(a) : 95 N·m (9.5 kg-m, 69.0 lb-ft)
5) Check to ensure that brake drum is free from dragging and
proper braking is obtained. Then remove vehicle from hoist
and perform brake test (foot brake and parking brake). NOTE:
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.
NOTE:
See NOTE at the beginning of this section.
