BRAKE

REAR BRAKE PAD

5. Rear Brake Pad

A: REMOVAL

1) Loosen wheel nuts, jack-up vehicle, support it
with safety stands, and remove wheel.
2) Remove bottom bolt.

3) Raise caliper body and suspend it securely.

NOTE:
Do not disconnect brake hose from caliper body.
4) Remove pad from support.

NOTE:
If brake pad is difficult to remove, use the same pro-
cedure as for front disc brake pad.
<Ref. to BR-20, REMOVAL, Front Brake Pad.>

B: INSTALLATION

1) Apply thin coat of Molykote AS880N (Part No.
26298AC000) to the frictional portion between pad
and pad clip.

CAUTION:
Do not allow oil or grease to adhere to the slid-
ing surface of pad and disc rotor.
2) Check disc rotor thickness and runout.
<Ref. to BR-27, INSPECTION, Rear Disc Rotor.>
3) Install pad on support.
4) Install caliper body on support.

Tightening torque:

39 N·m (4.0 kgf-m, 28.9 ft-lb)

NOTE:
If it is difficult to push piston during pad replace-
ment, loosen air bleeder to facilitate work.
5) Depress brake pedal several times.

6) Check that brake fluid level is at max. line.

C: INSPECTION

Check pad thickness (including back metal).

Pad thickness: A

Standard value

14.0 mm (0.551 in)

Wear limit

6.5 mm (0.256 in)

CAUTION:
• Always replace the pads for both the left and
right wheels at the same time. Also replace pad
clips if they are twisted or worn.
• A wear indicator is provided on the inner disc
brake pad. If the pad wears down to such an ex-
tent that the end of the wear indicator contacts
the disc rotor, a squeaking sound is produced
as the wheel rotates. If this sound is heard, re-
place the pad.
• Replace pad if there is oil or grease on it.

REAR DISC ROTOR

6. Rear Disc Rotor

A: REMOVAL

1) Lift-up vehicle and remove wheels.
2) Remove the two mounting bolts and remove the
disc brake assembly.

3) Suspend the disc brake assembly so that the
hose is not stretched.
4) Pull down and release parking brake.
5) Remove the disc rotor.

NOTE:
If the disc rotor is difficult to remove try the following
two methods in order.

(1) Turn adjusting screw using a slot-type
screwdriver until brake shoe gets away enough
from the disc rotor.

(2) If disc rotor seizes up within hub, drive disc
rotor out by installing an 8-mm bolt in holes B on
the rotor.

B: INSTALLATION

1) Install in the reverse order of removal.
2) Adjust parking brake. <Ref. to PB-11, ADJUST-
MENT, Parking Brake Assembly.>

C: INSPECTION

1) Secure disc rotor by tightening the five wheel
nuts.
2) Set a dial gauge on the disc rotor. Turn disc rotor
to check runout.

CAUTION:
Securely fix disc rotor to hub.

NOTE:
• Make sure that dial gauge is set 5 mm (0.20 in)
inward of rotor outer perimeter.
• If disc rotor runout is above standard value, in-
spect play of hub bearing axial direction and runout
of axle hub.
<Ref. to DS-27, INSPECTION, Hub Unit Bearing.>

Disc rotor runout limit:

0.075 mm (0.0030 in)

(1) Adjusting screw

(2) Cover

(3) Slot-type screwdriver

(4) Back plate

10 mm (0.39 in)

Service limit

8.5 mm (0.335 in)

3) Remove bolt securing lock pin to caliper body.

4) Raise caliper body and move it toward vehicle
center to separate it from support.
5) Remove support from back plate.

NOTE:
