<<A>> PISTON BOOT/PISTON REMOVAL
CAUTION
Do not remove one piston completely before trying to
remove the other piston, because it will become impossi-
ble to remove other pistons.
Remove the pistons by pumping in air slowly from the brake
hose connection. Be sure to use a wood block and adjust the
height of the four pistons so that the pistons protrude evenly.
.
<<B>> PISTON SEAL REMOVAL
CAUTION
To prevent damage to inner cylinder, do not use a
flat-tipped screwdriver or other tool.
1. Remove the piston seal with finger tip.
2. Clean the piston surface and cylinder inner face with alcohol
or specified brake fluid.

.
BRAKE PAD WEAR CHECK
WARNING
•
Always replace both brake pads on each wheel as
a set (both front wheels or both rear wheels). Fail-
ure to do so will result in uneven braking, which
may cause unreliable brake operation.
•
If there is significant difference in the thickness of
the pads on the left and right sides, check the
moving parts.
Measure thickness at the thinnest, most worn area of the pad.
Replace the pad assembly if pad thickness is less than the limit
value.
Standard value: 9.85 mm (0.39 inch)
Limit: 2.0 mm (0.08 inch)
