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.

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).

(a) Install the dust boots into the brake cylinder.
(b) Insure that the boot is secured firmly to the brake cyl-
inder groove.

REMOVAL OF REAR BRAKE
1. INSPECT SHOE LINING THICKNESS
Remove the inspection hole plug, and check the shoe lin-
ing the thickness through the hole.
If less than minimum, replace the shoes.
Minimum thickness: 1.0 mm (0.039 in.)
2. REMOVE REAR WHEEL
3. REMOVE BRAKE DRUM
HINT: If the brake drum cannot be removed easily, per-
form the following steps.
(a) Insert a bent wire or an equivalent through the hole
in the brake drum, and hold the automatic adjusting
lever away from the adjuster.
(b) Using a screwdriver, reduce the brake shoe adjust-
ment by turning the adjuster.

2. MEASURE BRAKE SHOE LINING THICKNESS
Standard thickness: 5.0 mm (0.197 in. )
Minimum thickness: 1 .0 mm (0.039 in.)
If the shoe lining is less than minimum or shows signs of
uneven wear, replace the brake shoes.
HINT: If any of the brake shoes have to be replaced, re-
place all of the rear shoes in order to maintain even brak-
ing. 9. IF NECESSARY, DISASSEMBLE WHEEL CYLINDER

3. MEASURE BRAKE DRUM INSIDE DIAMETER
Standard inside diameter: 228.6 mm (9.000 in.)
Maximum inside diameter: 230.6 mm (9.079 in.)
If the drum is scored or worn, the brake drum may be lathed
to the maximum inside diameter.

AND LEVER
Using a feeler gauge, measure the clearance.
Standard clearance: Less than 0.35 mm (0.0138 in.)
If the clearance is not within specification, replace the shim
with one of the correct size. 4. INSPECT REAR BRAKE LINING AND DRUM FOR
PROPER CONTACT
If the contact between the brake lining and drum is improp-
er, repair the lining with a brake shoe grinder, or replace
the brake shoe assembly.
6. IF NECESSARY, REPLACE SHIM
