9. CHECK CLEARANCE BETWEEN BRAKE SHOES AND
DRUM
(a) Remove the brake drum.
(b) Measure the brake drum inside diameter and diame-
ter of the brake shoes. Check that the difference be-
tween the diameters is the correct shoe clearance.
Shoe clearance: 0.6 mm (0.024 in.)
If incorrect, check the parking brake system.
10. INSTALL BRAKE DRUM
11. INSTALL REAR WHEEL
12. FILL BRAKE RESERVOIR WITH BRAKE FLUID AND
BLEED BRAKE SYSTEM
(See page BR±7)
13. CHECK FOR FLUID LEAKAGE(d) Pull the parking brake lever all the way up until a click-
ing sound can no longer be heard.

REPLACEMENT OF BRAKE PADS
HINT: If a squealing noise occurs from the 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.
1. REMOVE REAR WHEEL
Remove the wheel and temporarily fasten the rotor disc
with the hub nuts.

4. REMOVE FOLLOWING PARTS:
(a) Two brake pads
(b) Four anti±squeal shims
(c) Four pad support plates
5. CHECK ROTOR DISC THICKNESS
(See step 2 on page BR±39)
6. CHECK ROTOR DISC RUNOUT
(See step 3 on page BR±39)
7. INSTALL PAD SUPPORT PLATES
Install the four pad support plates. 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 I0.039 in.)
(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 the installation bolt from the torque plate.
± BRAKE SYSTEMRear BrakeBR±35

9. INSTALL CYLINDER
(a) Draw out a small amount of brake fluid from the res-
ervoir.
(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. 8. INSTALL NEW PADS
(a) Install the two anti±squeal shims to the each pad.
HINT: Apply disc brake grease to the both side of the inner
anti±squeal shim.
(b) Install the two pads so the wear indicator plate is at
the bottom side.
NOTICE: Do not allow oil or grease to get on the rub±
bing face.
(d) Install and. torque the installation
bolt.
Torque: 200 kg±cm (14 ft±Ib, 20 N±m)

3. MEASURE ROTOR DISC RUNOUT
Measure the rotor disc runout at 10 mm (0.39 in.) from the
outer edge of the rotor disc.
Maximum. disc runout: 0.15 mm (0.0059 in.)
If the runout is greater than the maximum, replace the
disc.
HINT: Before measuring the runout, confirm that the hub
bearing play is within speification.
4. IF NECESSARY, REPLACE ROTOR DISC
(a) Remove the axle carrier mounting bolt and nut of up-
per side.
(b) Remove the torque plate.
(e) Remove the hub nuts of the temporarily installed disc
and pull off the rotor disc.
(d) Install a new rotor disc and loosely install the hub
nuts.
INSPECTION AND REPAIR OF REAR
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: 10.0 mm (0.394 in.)
Minimum thickness: 9.0 mm (0.354 in.)
If the disc is scored or worn, or if thickness is less than
minimum, repair or replace the disc.
