The brake track is constructed of stainless steel. The brake track includes a first track on a first side of the brake surface core portion, a second track on a second side of the brake surface core portion, and a connecting portion extending over a peripheral edge of the brake surface core portion between the first and second tracks.

A brake drum includes an outer drum, at least one layer of heat resistant adhesive, provided at least on the inner radial surface of the outer drum, and an inner drum provided inside the outer drum connected with the outer drum via the at least one adhesive layer.

A component of a brake for a vehicle, having a metallic base body with a surface provided with a coating which includes an intermediate layer lying on the base body and a covering layer lying on the intermediate layer. The covering layer is formed from a stainless steel matrix with hard material particles embedded therein. The hard material particles embedded in the stainless steel matrix have an average grain diameter of 10-125 μm and have a non-melted core region consisting of uninfluenced material of the hard material particles, which core region is surrounded at least in sections by a mixing zone formed from material of the stainless steel matrix and material of the respective hard material particle, via which mixing zone the hard material particles are in each case materially bonded to the stainless steel matrix. Also, a method by which a component coated in this way is produced.

A method of making a fibrous part is provided. The method may comprise forming a porous structure with an annular geometry. A first entrance channel and a second entrance channel may be formed with the entrance channels defined by a surface of the preform. The entrance channels may also extend in a radial direction from an inner diameter of the annular porous structure partially across the surface. An exit channel may be formed between the entrance channels and defined by the surface. The exit channel may extend in a radial direction from an outer diameter of the annular porous structure partially across the surface.

A method makes brake discs of fiber-reinforced materials. Each brake disc includes a braking band having a predefined thickness. At least one fiber layer having a predefined width is formed and wound around the mandrel to form a coaxially hollow cylindrical body having an outer diameter and an inner diameter substantially equivalent to the mandrel diameter. The fiber layer is wound around the mandrel in a winding direction substantially parallel to the direction of the layer length. The semi-finished cylindrical body is cut in slices transversally to the longitudinal axis of the cylindrical body in predefined thicknesses. Each slice is a disc-shaped body defining the braking band of a brake disc. The cylindrical body is needled according to a substantially radial direction to orient part of the fibers according to this direction by arranging the fibers in connection between adjacent coils of the fiber layer wound around the mandrel.

A bicycle disc brake rotor is provided. The bicycle disc brake rotor includes a friction disc having a center axis and including a first braking surface and a second braking surface. The bicycle disc brake rotor also includes a mounting adapter attached to a bicycle wheel and coupled to the friction disc through a coupling structure, wherein the coupling structure includes a first mating surface pair comprising a first adapter surface and a first disc surface, and a second mating surface pair comprising a second adapter surface and a second disc surface.

A brake disk includes a first abrasive disk, a second abrasive disk and a heat dissipation disk co-axially sandwiched between the first abrasive disk and the second abrasive disk. A middle disk is co-axially mounted onto the first abrasive disk and the second abrasive disk, wherein the middle disk is adapted to be mounted to a hub. A specific heat capacity coefficient of the heat dissipation disk is greater than that of the first abrasive disk and the second abrasive disk for absorbing thermal energy from the first abrasive disk and the second abrasive disk and lowering the temperature of the first abrasive disk and the second abrasive disk during braking.

An internally ventilated brake disc with a disc coning reducing arrangement is provided in which temperature differences between inboard and outboard sides of the brake disc are minimized in order to reduce coning-causing differential thermal expansion. Between a radially inner region of a brake disc that includes brake disc-to-axle hub mounting features and a radially outer region the mass of the inboard side of the brake disc is distributed in a manner that reduces the amount of differential thermal expansion occurring during brake application between the inboard and outboard sides of the brake disc, thereby minimizing thermally-induced coning effects. The inboard side disc plate portion may having an increasing axial thickness in the direction from the radially outer region to the radially inner region, providing additional material mass to receive and dissipate heat energy received during a braking event.

A bicycle disc brake rotor including a center rotational axis is provided with an outer member including a braking portion extending in a rotation direction of the bicycle disc brake rotor and an inner member located at an inner side of the outer member in a radial direction of the bicycle disc brake rotor and coupled to the outer member. At least one of the outer member and the inner member includes a displacement reducing structure configured to reduce displacement of the braking portion in an axial direction of the bicycle disc brake rotor.

The present disclosure describes brake rotor preforms and brake pads configured to reduce fracturing and failure of brake rotors by distributing the axial force applied during braking across butt joints between abutting segments of preforms and rotors manufactured therefrom. The preforms comprise a spiral annular structure formed about a longitudinal axis from a plurality of carbon fiber precursor tow segments having a partial annular shape. Each segment is asymmetrical when viewed in the longitudinal axis direction and configured so planes defined by the segment's ends are never coplanar with planes extending radially from the longitudinal axis. The brake pads have a partial annular shape and ends adapted to prevent planes defined by the ends from being coplanar during use with a plane extending radially from a brake rotor longitudinal axis.
