B4M1167
A: ON-CAR SERVICE
1. PAD
1) Remove lock pin.
2) Raise caliper body.
3) Remove pad.
B4M1168A
4) Check pad thickness A.
Pad thickness
(including back metal)
mm (in)Standard value 17 (0.67)
Wear limit 7.5 (0.295)
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 extent 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, replace the pad.

Replace pad if there is oil or grease on it.
B4M1169A
5) Apply thin coat of PBC GREASE (Part No. 003607000)
to the frictional portion between pad and pad clip.
6) Install pads on support.
7) Install caliper body on support.
NOTE:
If it is difficult to push piston during pad replacement,
loosen air bleeder to facilitate work.
G4M0364
2. DISC ROTOR
1) Install disc rotor by tightening the five wheel nuts.
2) Set a dial gauge on the disc rotor. Turn disc rotor to
check runout.
NOTE:
Make sure that dial gauge is set 5 mm (0.20 in) inward of
rotor outer perimeter.
Disc rotor runout limit:
0.075 mm (0.0030 in)

B: REMOVAL
1) Remove union bolt and disconnect brake hose from
caliper body assembly.
B4M1171
2) Remove bolt securing lock pin to caliper body.
3) Raise caliper body and move it toward vehicle center to
separate it from support.
B4M1192A
4) Remove support from housing.
NOTE:
Remove support only when replacing it or the rotor. It need
not be removed when servicing caliper body assembly.
G4M0365
5) Remove disc rotor from hub.
NOTE:
If disc rotor seizes up within hub, drive disc rotor out by
installing an 8-mm bolt in holes B on the rotor.
6) Clean mud and foreign particles from caliper body
assembly and support.
