ABSTRACT:
A protective cap (11) for a bolt guide of a spot-type disc brake, comprises an elastic (pleated) bellows, one end portion of which is fastened to the periphery of a first cylindrical part, while the other end portion thereof is secured to the periphery of a second cylindrical part. A rigid reinforcing and retaining member (15, 16) is provided on each one of said end portions (12, 13) with both reinforcing and retaining members being arranged with at least part of their radial extension on the same radius. To avoid damage to the cylindrical part and the guide surface thereof, at least one (16) of the reinforcing and retaining members is secured radially outwards at the corresponding end portion of the elastic bellows. Thus, an axially extending annular surface is formed which is free from the material of the elastic bellows and wherein the reinforcing and retaining members (16) together with this annular surface is arranged in press fit in a corresponding bore (20) of the associated cylindrical part.
