ASSEMBLY SERVICE POINT

.

>>A<< REAR BRAKE PIN INSTALLATION
Attach a guide pin (with "g" on the bolt head) at the bleeder nip-
ple side of the caliper body and a lock pin (with "l" on the bolt
head) at the opposite side.

INSPECTION

M1351008300039

• 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 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). 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 slid-
ing condition of the piston and slide pins.

1. Measure thickness at the thinnest and most worn area of the

pad.

Standard value: 10 mm (0.39 inch)
Minimum limit: 2.0 mm (0.08 inch)

2. Replace the pad assembly if pad thickness is less than the

limit value.
