Abstract: A fixed caliper brake includes a caliper housing that includes two opposing blocks (14), each of which includes an axial recess (16), an axial surface (20) for supporting a brake pad, and elements (40, 22) for mounting and axially and slidably guiding the brake pad, the elements including a pad spring (40) that is attached to each related lug (26) of the brake pad (12), and a steel lamellar element (22) having a spring and being received in the related recess (16).

Abstract: A disk brake has a fork with two opposing arms each having a C-shaped axial seat designed to receive a brake pad with two opposing lateral lugs, each lug receiving a pad spring having at least one lower sliding branch, in which a laminar element is interposed between the lug and C-shaped seat, the element having a first lower sliding flange receiving the sliding branch of the pad spring and a second upper vertical supporting flange in the seat. The laminar element is elastically deformable between an initial free state in which the sliding flange and the lower face of the seat form a first acute angle and at least one state of loading by the pad spring in which the sliding flange forms a second acute or zero angle that is less than the first acute angle, and in which the sliding branch of the pad spring is pre-stressed.

Abstract: A disk brake (1) usually comprises a caliper (2), a carrier (3) and friction means (8, 9). The caliper is slideably mounted on the carrier. To improve the braking performance of such a disk brake while reducing the manufacturing cost, the invention provides that a first friction means is retained rotationally by the carrier while a second friction means is retained rotationally by the caliper. The disk brake according to the present invention is also characterized in that the carrier has at least two guide pins (17, 18), the caliper being slideably mounted on the carrier via these two pins, the caliper having at least two bores (19, 20) able to receive one pin each.
