±6 N´m (5.3±0.6 kg-m, 38.3±4.3 ft-lb)
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 pads if there is oil or grease on
them.
3) Apply thin coat of PBC GREASE (Part No.
003607000) to the frictional portion between pad
