<p>PURPOSE: To extremely reduce the cost of a pivot device of a shift saddle and provide a superior guide characteristic by improving a conventional shift saddle type disc brake. CONSTITUTION: A first guide bearing 21 is provided with elastomer guide bushes 33, 34, which have relatively long sliding surfaces. The guide bushes 33, 34 are so dimensioned that a sliding fitting exists relative to a first guide beam 11, and a second guide bearing 22 is provided with an elastomer guide bush 32, which has a relatively short sliding surface and is so dimensioned that the second guide beam 12 slides with a defined play.</p> |
