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 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, lock pin and guide
pin.

Measure thickness at the thinnest and most worn area of the
pad.
Replace the pad assembly if pad thickness is less than the limit
value.

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