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.

The invention relates to a dust sheet for a vehicle brake, configured for reducing brake noise, wherein the dust sheet comprises sub-centimetre damping structures for attenuating airborne sound, the damping structures being formed by a plurality of holes and/or a plurality of embossings. The invention also relates to a brake system for a vehicle, in particular a disk brake system, comprising such a dust sheet.

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.

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 protective cover for a disc is for being disposed on a fork of a bicycle. The fork has a shaft hole. A direction toward which an opening of the shaft hole faces is defined as an axial direction. The bicycle further has a brake disc. The protective cover includes a shell body. As viewed in the axial direction, the shell body and the brake disc are located by the same side of the bicycle, and the brake disc is shielded by the shell body.

A rotor cover is provided that limits contact of a disc brake rotor with an object flying from a radially outer side of the disc brake rotor. The rotor cover covers a disc brake rotor, which is rotatable relative to a bicycle frame. The rotor cover includes a circumferential part that at least partially covers a circumferential edge of the disc brake rotor at a radially outer side of the disc brake rotor. The circumferential part includes at least three first pieces facing the circumferential edge of the disc brake rotor, and first openings provided between two adjacent ones of the first pieces in a circumferential direction of the disc brake rotor.

A rotor cover is provided that includes different portions and is configured to meet requirements of each portion. The rotor cover includes a positioning portion that is positioned relative to a bicycle frame or a disc brake rotor and a cover portion that is coupled to the positioning portion to cover the disc brake rotor. The cover portion and the positioning portion include different materials with respect to one another.

A caliper cover having a first support member and second support member engaged on a first mount and second mount affixed to opposite sides of a brake caliper. The first and second mounts are held engaged by the fixed spacing of the first and second member. Enhanced engagement is provided through a declining gap formed between opposing first and second portions of the mounts.

This disc brake includes a mounting member, a pair of brake pads, a caliper, a cover member, and a locking member. The caliper includes a cylinder part having a cylinder hole in which a piston for moving one of the pair of brake pads is disposed, a bridge part extending across an outer circumferential surface of a disc from the cylinder part, a plurality of claw parts formed on an extended distal end side of the bridge part and disposed to face the cylinder part, and a recessed part provided between the plurality of claw parts, having an opening at a disc radial direction inner end, and formed to face the cylinder hole. The locking member includes a fixing part fixed to the cover member, and a plurality of locking pieces extending from the fixing part in a direction inclined with respect to a movement direction of the piston.
