Abstract
A sealing boot for use in a disc brake assembly which includes a stationary support member having a support pin fixed thereto, and a caliper member having a boss portion slidably supported on the support pin. The sealing boot includes a bellows portion integrally formed at the opposite ends thereof with an outside cylindrical sealing portion coupled over the support pin and an inside cylindrical sealing portion coupled within an annular groove in the boss portion, the inside sealing portion being formed at its outer circumference with a first annular projection in contact with the bottom surface of the annular groove and at its inner circumference with a second annular projection sliding in contact with the support pin. The first annular projection of the inside sealing portion is formed at its one side with a steep annular surface directed outwardly and at its other side with a gentle slope annular surface and has a rounded annular head in contact with the bottom surface of the annular groove. The second annular projection is slightly displaced relative to the first annular projection.
