REPLACEMENT OF BRAKE PADS
HINT: If a squealing noise occurs from the front brakes
while driving, check the pad wear indicator. If there are
traces of the indicator contacting the rotor disc, the brake
pad should be replaced.

2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the cylinder inspection
hole and replace pads if not within specification.
Minimum thickness: 1.0 mm (0.039 in.)
4. REMOVE FOLLOWING PARTS:
(a) Two anti±squeal springs.
(b) Two brake pads
(c) Two or four anti±squeal shims
(d) Two pad wear indicator plates
(e) Four pad support plates 1. REMOVE FRONT WHEEL
Remove the wheel and temporarily fasten the rotor disc
with the hub nuts.
(b) Remove the brake cylinder and suspend it so the hose
is not stretched.
HINT: Do not disconnect the brake hose. 3. REMOVE CYLINDER FROM TORQUE PLATE
(a) Remove two installation bolts from the torque plate.

8. INSTALL NEW PADS
(a) Install new pad wear indicator plate to inner pad.
NINT: Be sure the arrow on the pad wear indicator
plate is pointing i n the direction of the disc rotation.
(b) (Except 2VZ±FE Engine of w/ A.B.S.)
Install the one anti±squeal shim to the each pad.
(c) (For 2VZ±FE Engine of w/ A.B.S.)
Install the two anti±squeal shims to the each pad.
HINT: Apply disc brake grease to both side of the inner
anti±squeal shim of the outside pad.
(d) Install the pads onto each support plate.
NOTICE: Do not allow oil or grease to get on the
rubbing face.
(e) Install the two anti±squeal springs.
9. INSTALL CYLINDER
(a) Draw out a small amount of brake fluid from the reser-
voir.
(b) Press in piston with a hammer handle or an equiva-
lent.
HINT: Always change the pad on one wheel at a time as
there is a possibility of the opposite piston flying out.
(c) Insert the brake cylinder carefully ±so the boot is not
wedged. 5. CHECK ROTOR DISC THICKNESS
(See step 2 on page BR±23)
6. CHECK ROTOR DISC RUNOUT
(See step 3 on page BR±23)
7. INSTALL PAD SUPPORT PLATES

REMOVAL OF CYLINDER
(See page BR±18)
1. DISCONNECT BRAKE LINE
Remove the union bolt and disconnect the brake line. Use
a container to catch the brake fluid.(d) Install and torque two installation bolts.
Torque: 400 kg±cm (29 ft±Ib, 39 N¿m)
10. INSTALL FRONT WHEEL
11. CHECK THAT FLUID LEVEL IS MAX LINE
2. REMOVE CYLINDER FROM TORQUE PLATE
Remove the two installation bolts and cylinder.
3. REMOVE PADS
(See step 4 on page BR±19)

3. REMOVE PISTON FROM CYLINDER
(a) Put a piece of cloth or an equivalent between the pis-
ton and cylinder.
(b) Use compressed air to remove the piston from the cyl-
inder.
CAUTION: Do not place your fingers in front of the piston
when using compressed air.
2. REMOVE CYLINDER BOOT SET RING AND CYLINDER
BOOT
Using a screwdriver, remove the cylinder boot set ring and
cylinder boot.
DISASSEMBLY OF CYLINDER
(See page BR±18)
1. REMOVE FOLLOWING PARTS:
(a) Two sliding bushings
(b) Four dust boots
4. REMOVE PISTON SEAL FROM BRAKE CYLINDER
Using a screwdriver, remove the piston seal.

3. MEASURE ROTOR DISC RUNOUT
HINT: Before measuring the runout, confirm that the front
hub bearing play is within specification.
Measure the rotor disc runout at 10 mm (0.39 in.) from the
outer edge of the rotor disc.
Maximum disc runout: 4.07 mm (0.0028 in.)
If the runout is greater than the maximum, inspect and ad-
just it following the procedure below:
Then replace the disc if necessary.
(a) Remove the torque plate from the knuckle.
(b) Remove the hub nuts of the temporarily installed disc
and pull off the rotor disc.
(c) Check that the hub bearing play is within specifica-
tion, and replace the bearing if not within specifica-
tion. (See page FA ± 7)
(d) Install the rotor disc and measure the disc runout,
then shift the rotor disc one fifth of a turn and measure
the disc runout. Similarly measure the runout at each
position, and select the position where the runout is
minimum.
INSPECTION AND REPAIR OF FRONT
BRAKE COMPONENTS
1. MEASURE PAD LINING THICKNESS
Standard thickness: 10.0 mm (0.394 in.)
Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the thickness is less than the minimum
or if it shows sign of uneven wear.
2. MEASURE ROTOR DISC THICKNESS
Standard thickness: 25.0 mm (4.984 in.)
Minimum thickness: 24.0 mm (0.945 in.)
If the disc is scored or worn, or if thickness is less than mini-
mum, repair or replace the disc.
(e) In this position, if the runout is within specification,
install the torque plate and torque the mounting bolts.
Torque: 1,090 kg±cm (79 ft±Ib, 107 N±m)
(f) If not within specification, replace the rotor disc, and
repeat (d) and (e).

1. APPLY LITHIUM SOAP BASE GLYCOL GREASE TO
PARTS INDICATED WITH ARROWS
4. INSTALL DUST BOOTS AND SLIDING BUSHING
(a) Install the dust boots into the brake cylinder.
(b) Insure that the boot is secured firmly to the brake cyl-
inder groove.
(c) Install the bushing into the boots.
(d) Insure that the boot is secured firmly to the bushing
groove. 3. INSTALL CYLINDER BOOT AND SET RING IN
