4) Check pad thickness (including back metal).
Pad thickness: A
Standard value
15.0 mm (0.591 in)
Wear limit
6.5 mm (0.256 in)
G4M0362
CAUTION:
IAlways replace the pads for both the left and
right wheels at the same time. Also replace pad
clips if they are twisted or worn.
IA 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.
IReplace pad if there is oil or grease on it.
5) Apply thin coat of PBC GREASE (Part No.
03607000) to the frictional portion between pad
and pad clip.
6) Install pad on support.

NOTE:
If it is difficult to push piston during pad
replacement, loosen air bleeder to facilitate work.
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.
G4M0382
NOTE:
Make sure that dial gauge is set 5 mm (0.20 in)
inward of rotor outer perimeter.
Disc rotor runout limit:
0.1 mm (0.004 in)
3) Measure disc rotor thickness.
G4M0383
NOTE:
Make sure that micrometer is set 5 mm (0.20 in)
inward of rotor outer perimeter.
Disc rotor thickness: A
Standard value
10 mm (0.39 in)
Service limit
8.5 mm (0.335 in)
NOTE:
When removing disc rotor, refer to instructions
under Parking Brake.
