ABSTRACT:
The present invention is an improved cantilever brake for a cycle. The cantilever brake is attachable to a pair of attachment studs extending from a cycle frame. The cantilever brake includes a pair of elongate brake arms each having an integral brake arm base at its proximal end. The brake arm base forms a cylindrical cavity transverse the brake arm, the cylindrical cavity having a main portion with a diameter to receive a main body portion of the attachment stud and an enlarged diameter portion at one end of a diameter to receive an enlarged shoulder of an attachment stud. The brake arm, which is rotatable around the attachment stud, extends from the brake arm base over the enlarged diameter portion of the brake arm base cylindrical cavity. A pair of brake pad adjustment assemblies each receives one of the pair of cylindrical brake arms. The brake pad adjustment assemblies are movable lengthwise of the cylindrical brake arm and are rotatable about the cylindrical brake arm. Each brake pad adjustment assembly includes a first clamp for gripping a pad post of a brake pad assembly and a second clamp for maintaining the brake pad adjustment assembly at a select position lengthwise and rotation wise of the brake arm. With an attachment stud received in the cylindrical cavity of the brake arm base and the first clamp rotated away from the enlarged cylindrical portion, the first clamp overlies the attachment stud.
