INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 10.0 mm (0.39 in.)
Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the pad's thickness is at the minimum or if
it shows signs of uneven wear.
2. MEASURE DISC THICKNESS
(a) Temporarily fasten the disc with the 3 hub nuts.
(b) Using a micrometer, measure the disc thickness.
Standard thickness: 18.0 mm (0.709 in.)
Minimum thickness: 16.0 mm (0.611 in.)
Replace the disc if the thickness of the disc is at the minimum
thickness or less. Replace the disc or grind it on a lathe if it is
scored or is worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout at a position 10
mm (0.39 in.) from the outside edge.
Maximum disc runout: 0.1 mm (0.0039 in.)
If the disc's runout is at the maximum value or greater, check the
bearing play is in the axial direction and check the axle hub run-
out (See page SA±95). If the bearing play and axle hub runout
are not abnormal, adjust the disc runout or grind it on an ºOn±
Carº brake lathe.
4. IF NECESSARY, ADJUST DISC RUNOUT
(a) Remove the 2 bolts and torque plate from the backing
plate.
(b) Remove the hub nuts and the disc. Reinstall the disc ro-
tating 1/6 of a turn from its original position on the hub.
Install and torque the hub nuts.
Torque: 110 N´m (1,122 kgf´cm, 81 ft´lbf)
Remeasure the disc runout. Make a note of the runout
and the disc's position on the hub.
(c) Repeat (b) until the disc has been installed on the 4 re-
maining hub positions.
(d) If the minimum runout recorded in (b) and (c) is less than
0.1 mm (0.0039 in.), install the disc in that position.
(e) If the minimum runout recorded in (b) and (c) is greater
than 0.1 mm (0.0039 in.), replace the disc and repeat step
3.
(f) Install the torque plate and tighten the 2 bolts.
Torque: 105 N´m (1,070 kgf´cm, 77 ft´lbf)

DISASSEMBLY
1. REMOVE REAR WHEEL
Torque: 110 N´m (1,122 kgf´cm, 81 ft´lbf)
2. REMOVE REAR DISC BRAKE ASSEMBLY
(a) Remove the 2 mounting bolts and remove the disc brake
assembly.
Torque: 105 N´m (1,070 kgf´cm, 77 ft´lbf)
(b) Suspend the disc brake securely and so the hose is not
stretched.
3. REMOVE DISC
(a) Release the parking brake lever.
(b) Place matchmarks on the disc and rear axle hub.
(c) Remove the disc.
HINT:

If the disc cannot be removed easily, turn the shoe adjust-
er until the wheel turns freely.

If there are no matchmarks, temporarily install the disc,
then measure the disc runout and install the disc in posi-
tion (See page BR±39).
4. REMOVE SHOE RETURN SPRINGS
Using needle±nose pliers, remove the 2 shoe return springs.
5. REMOVE SHOE STRUT WITH SPRING
HINT:
At the time of reassembly, install the strut with the spring facing
forward.
6. REMOVE SHOE ADJUSTER
Slide the front shoe toward outside, remove the shoe adjuster.
7. REMOVE FRONT SHOE

INSPECTION
1. INSPECT DISASSEMBLED PARTS
Inspect the disassembled parts for wear, rust or damage.
2. MEASURE BRAKE SHOE LINING THICKNESS
Using a ruler, measure the thickness of the shoe lining.
Standard thickness: 4.0 mm (0.157 in.)
Minimum thickness: 1.0 mm (0.039 in.)
If the lining thickness is at the minimum thickness or less, or if
there is severe and uneven wear, replace the brake shoe.
3. MEASURE BRAKE DISC INSIDE DIAMETER
Using a brake drum gauge or equivalent, measure the inside di-
ameter of the disc.
Standard inside diameter: 210 mm (8.27 in.)
Maximum inside diameter: 211 mm (8.31 in.)
Replace the disc if the inside diameter is at the maximum value
or more.
Replace the disc or grind it with a lathe if the disc is scored or
worn unevenly.
4. INSPECT PARKING BRAKE SHOE LINING AND DISC
FOR PROPER CONTACT
Apply chalk to the inside surface of the disc, then grind down
the brake shoe lining to fit. If the contact between the disc and
the brake shoe lining is improper, repair it using a brake shoe
grinder or replace the brake shoe assembly.
5. MEASURE CLEARANCE BETWEEN PARKING
BRAKE SHOE AND LEVER
Using a feeler gauge, measure the clearance.
Standard clearance: Less than 0.25 mm (0.010 in.)
If the clearance is not within the specification, replace the shim
with one of the correct size.
