<<A>> PISTON BOOT/PISTON REMOVAL

CAUTION

Blow air little by little to remove the piston. The
piston will rush out if a force of air is applied
suddenly.

Place a piece of wood, etc. against the caliper body
as shown. Blow compressed air through the brake
hose to remove the piston boot and piston.

<<B>> PISTON SEAL REMOVAL

CAUTION

Do not use a flat-tipped screwdriver or similar
tool to remove piston seal. These may damage
the inner side of the cylinder.

1. Remove the piston seal with your finger tip.

2. Clean the piston surface and inner cylinder with

alcohol or brake fluid DOT 3 or DOT 4.

INSPECTION

M1351007300304

• Check the cylinder for wear, damage or rust.

• Check the piston surface for wear, damage or

rust.

• Check the caliper body or sleeve for wear.

• Check the pad for damage or adhesion of grease,

check the backing plate for damage.

PAD WEAR CHECK

WARNING

•

Always replace both brake pads on each
wheel as a set. Failure 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 sliding condition of the
piston and slide pins.

1. Measure thickness at the thinnest and most worn

area of the pad.

Standard value: 10.0 mm
Minimum limit: 2.0 mm

2. Replace the pad assembly if pad thickness is less

than the limit value.
