The invention relates to a dust sheet for a vehicle brake configured for reducing brake noise, to a disk brake system comprising a dust sheet and to a method for making a dust sheet, wherein the dust sheet comprises, at least in a section, two or more layers.

A fastening device for a vehicle disc brake having a brake carrier includes holding fixture formed in the brake carrier for receiving a speed sensor. The brake carrier includes fastening members for mounting to a flange of the vehicle. The speed sensor is used for an anti-lock braking system to detect wheel slip. The holding fixture is in the form of a bore. The bore may be formed in the strut facing the axle or in an extension of one of the fastening members of the brake carrier. The speed sensor is aligned in its extension direction axially with an exciter in or on the brake disc or in the axle. The speed sensor is attached to a cable that does not need to be guided past the vehicle flange.

A piston assembly for a disc brake assembly having a housing with a passage includes a piston provided in the passage and axially movable therein in response to hydraulic pressure. A rotatable spindle extends into the piston. A nut is threadably connected to the spindle such that rotation of the spindle results in axial movement of the nut within the passage to thereby axially move the piston. A damping member encircles the nut and has one of a sliding and rolling interface with the piston in response to relative axial movement between the nut and the piston to prevent rattling of the nut against the piston.

A guard plate for a disk brake of a vehicle includes a base element having at least one fastening section for arranging the base element in relation to a brake disk of the disk brake and at least one extension element. The at least one extension element may be movable relative to the base element and is configured to be moved and fixed between an initial position and at least one extension position.

It is possible to prevent occurrence of a resonance phenomenon of a hydraulic unit and to improve attachability/detachability of the hydraulic unit to/from a bracket. A support section (42, 43) includes: a fixture member (80) that is fixed to a housing (30) for a hydraulic unit (10); and a vibration absorbing member (75) that is interposed between the housing (30) and a bracket (41) and has a through-hole (75a) through which the fixture member (80) passes. The vibration absorbing member (75) includes two vibration absorbing members (75B, 75C, 75D) having different rebound resilience from each other. In a state where the vibration absorbing member (75) is partially accommodated in a recessed section (47) of the bracket (41), the vibration absorbing member (75) is held between the housing (30) and the bracket (41).

A ventilated brake rotor rotationally associated with a vehicle element to be braked, having a rotation axis and defining an axial direction, parallel to or coinciding with the rotation axis, a radial direction perpendicular to the axial direction and a circumferential direction, perpendicular to both the axial and radial directions, has a cup-shaped body having at least one ventilation opening passing through a cup-shaped body thickness to allow passage of a cooling fluid for cooling the ventilated brake rotor, at least one front annular portion for connecting the ventilated brake rotor to the vehicle element to be braked, and a side portion extending from the at least one front annular portion at least in the axial direction. A protective element shields the at least one ventilation opening preventing foreign bodies from entering into the cup-shaped body and allowing the cooling fluid to cross the at least one ventilation opening.

A cover for temporary protective shielding of a brake includes a body. The body has a cylindrical structure with one open end; a central position of an upper bottom surface of the cover body includes a central hole; a front-end position of the upper bottom surface includes a downwardly recessed mounting groove for mounting a brake caliper; a limiting step for position limiting is provided at a connection and transition position between a front-end inner circumferential wall and an inner circumferential wall of the body; the inner circumferential wall includes snap joints and heat radiating grooves; the inner circumferential wall of the protective cover body includes compensation columns that protrude outwards from the inner circumferential wall. The cover is mounted on a peripheral edge of the brake protective plate. By using compensation columns with a hollow semi-cylindrical structure, the cover can be universally mounted at peripheral edges of protective plates having various shapes.

A disc brake for a utility vehicle is provided. The brake caliper of the disk brake is configured to be mounted in an axially-displaceable manner on a stationary brake carrier by two fastening elements. The two fastening elements are plain bearings arranged in respective bores of the brake caliper, one as a locating bearing and the other as a floating bearing. The floating bearing includes a sliding bush made from a plastic, in particular an elastomer, and a guide rod configured to be connected to the brake carrier is mounted. The sliding bush is held on the guide rod secured against axial displacement between the guide rod and the inner wall of the respective brake caliper bore. The sliding bush is configured to carry a lubricant on its circumferentially outer surface and has sealing lips projects radially outward that bear against the inner wall of the respective bore.

A caliper for disc brake comprising a caliper body housing at least one pair of pads disposed on opposite sides along an axial direction and comprising at least one thrust piston which interfaces with the pad so as to press it against the associable brake disc, and at least one return spring that exerts a return thrust on the support plate of the pad. The return spring comprises a fixing portion to the caliper body that extends from axially opposite sides in separate thrust branches, each thrust branch interfacing with a support plate of a related pad. Each thrust branch comprises a first rectilinear portion that extends towards the corresponding pad, a curved portion, integral with the first rectilinear portion and folded in approach to the fixing portion, a second rectilinear portion that extends from the curved portion in approach to the fixing portion. The second rectilinear portion terminates with a free cantilevered end and interfaces with an edge of the support plate.
