DISASSEMBLY SERVICE POINTS
CAUTION
Take care not to contact the parts or tools to the
caliper because the paint of caliper will be
scratched. And if there is brake fluid on the cali-
per, wipe it off quickly.
When disassembling the disc brakes, disassemble
both sides (left and right) as a set.
<<A>> PISTON BOOT/PISTON REMOVAL
CAUTION
Do not remove one piston completely before try-
ing to remove the other piston, because it will
become impossible to remove other pistons.
AC212148
AB
Wood block
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 inner cylinder with
alcohol or brake fluid DOT 3 or DOT 4.
INSPECTION
M1351006300431
• Check the cylinder for wear, damage or rust.
• Check the piston surface for wear, damage or
rust.
• Check the caliper body for wear.
• Check the pad for damage or adhesion of grease,
check the backing metal for damage.
PAD WEAR CHECK
WARNING
•
Always replace both brake pads on each
wheel as a set (both front wheels or both
rear wheels). Failure to do so will result in
uneven braking, which may cause unrelia-
ble brake operation.
•
ACX00690
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: 10.0 mm
Minimum limit: 2.0 mm
