Abstract: An improvement of an anti-rust cover for covering the outer side of a disc rotor of a vehicle disc brake. The anti-rust cover, which is capable of removably attached to the outer periphery of a dust cover, for covering the inner side of the disc rotor, at its outer periphery is characterized in that an engaging member disposed, on the inner surface and in the vicinity of the outer periphery, thereof for being engaged with the outer periphery of the dust cover, is utilized to afford a recess portion large enough to allow at least a part of a human finger to be held therein, and the anti-rust cover can be easily removed by means of holding a finger in the recess portion when required to be taken away.

Abstract: An improved anti-rust cover for covering the outer side of a disc rotor of a vehicle disc brake. The anti-rust cover, which is capable of removably attached to the outer periphery of a dust cover for covering the inner side of the disc rotor at its outer periphery, is characterized in that the same is provided with a bridge portion formed by partly narrowing the width of the annular portion thereof and a detoured path portion formed by protruding a part of the bridge portion outwardly from base of the bridge portion to encircle a gate shaped open space in it.

Abstract: A rust preventing device for keeping a rotor of a disc brake from rusting. The rotor has an inner surface and an outer surface covered by a dust shield. The inner surface of the rotor is covered by a rust preventing cover. The rust preventing cover is secured to the dust shield in a snapping manner.

Abstract: In a sliding type disk brake assembly having a caliper movable on a pair of shoulders of a support member, a fluid actuator on one side of the caliper to press an inner brake shoe against one face of a rotary disk, and a reaction portion on the opposite side of the caliper to press an outer brake shoe against the other face of the disk, the reaction portion being provided substantially at its central portion with a pair of rectangular shaped recesses and the backing plate of the outer brake shoe having a pair of abutment flanges engaged within the recesses, the length dimension of the backing plate being smaller than the spacing between the two shoulders of the support member.
