Remove pads from support.

Fig. 10-9 Removing pad
NOTE:
a. Do not touch the brake pedal after
the pads have been removed.
b. Do not disconnect hose.
2) Inspection
1) Pad
Replace if it is wet with oil or worn.
Pad thickness including back metal
mm (in)
Standard
15.0 (0.591)
Usable limit 7.5 (0.295)
NOTE:
a. 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.
b. The clip incorporated with inner
pad is also used as a warning device
for worn pads. When wear occurs
on the pad to such an extent that
the clip comes into contact with
the rotor, unusual noise is produced
when brakes are not applied. If
such a noise is noticed, replace
the pad.
2) Disc rotor
Check for wear and damage, and
correct or replace if abnormal.

3) Installation
1) It
is necessary to push back piston
into cylinder ,since piston protrudes
from cylinder in proportion to the
amount of pad wear, and the gap
where pads are to be inserted is
narrow.
Rotate piston clockwise with Wrench
(925590000) to force in piston to
caliper body, and set the piston notch
to the specified position.

piston notch
After pushing back piston, check
piston boot for twist.
If
twisted,
correct twist using a strip driver.
NOTE:
a. Do not disconnect hose.
b. Always return the piston to that
point which allows only a minimum
clearance for the pad to be inserted.
c. Be sure to use the special tool
when pushing in the piston to the
caliper body. If the piston is pushed
into the caliper body with a vice
and without rotating it, the spindle
(5·thread) may be buckled. To
prevent this, the piston should be
rotated clockwise when pushed into
the caliper body.
