ABSTRACT:
The oil tightness between a union and a seat portion on the outer side surface of a caliper is maintained by a copper packing. A rubber packing is provided on the outside of the copper packing so as to prevent water drops from adhering to the copper packing. As a result, copper ions never dissolves into the water drops, so that the aluminum caliper is prevented from corroding.
