The brake disc is formed from a hypereutectic aluminum silicon alloy, which has a silicon content of 13 to 21 wt. % and a maximum content of 0.3 wt. % of copper. The brake pad is configured to act on the brake disc and includes a NAO friction material.

A brake housing assembly including a brake housing and a bearing support. The brake housing may have a recess defining a recess axis, the recess having a base and a recess wall, the base defining a base contour. The bearing support may have a projection defining a bearing support axis, the projection having an end and a projection wall, the end defining an end contour corresponding to the base contour such that with the end in engagement with the base the end contour and base contour cooperate to align the bearing support axis with the recess axis.

A brake pad assembly for a bicycle includes a first brake pad, a second brake pad, and a spreader spring. The first brake pad has a first backing plate with a first rotor facing surface, and a first friction pad secured to the rotor facing surface. The second brake pad has a second backing plate with a second rotor facing surface, and a second friction pad secured to the second rotor facing surface and facing the first friction pad. The spreader spring has a first leaf that is fixed to the first brake pad and a second leaf that is fixed to the second brake pad. At least a portion of the first leaf is positioned between the first rotor facing surface and the first friction pad, and at least a portion of the second leaf is positioned between the second rotor facing surface and the second friction pad.

A brake disc, in which a hat part that is mounted on a hub and a disc part that provides friction surfaces with brake pads are made of different materials and are combined, includes: a plurality of bridges protruding and circumferentially arranged around an edge of the hat part for coupling to the disc part; a plurality of vanes defining a channel for air flow; and a plurality of coupling pillars, which are fixedly in contact with the bridges, respectively, arranged between a pair of disc plates. The coupling pillars are fixedly in contact with both sides of the bridges while exposing front ends of the bridges.

A device that produces component from a plastics material by injection moulding includes two mould halves. The two mould halves can be pressed together releasably and, in the pressed-together state, form at least one gate region and at least one common cavity for moulding the plastics material. The gate region is fluidically connected to the cavity for the purpose of introducing the plastics material into the cavity. At least one deflecting element is provided, which is arranged movably in the gate region and is formed to prevent or at least to impede flowing of the plastics material through a partial region of the gate region, the location of which results from the respective position of the deflecting element, in a manner depending on the respective position of the deflecting element

Composite parts (10), methods of making the same (400), and tooling systems (200) for making the same are disclosed. According to one example, a high-pressure die casting process is used to manufacture a composite part (10) that is made from a composite metal material (12) with a metal matrix phase (20) and a particle phase (22) and includes an interior region (14) and an exterior region (16), where an average concentration of the particle phase (22) in the composite metal material (12) is higher in the exterior region (16) than in the interior region (14). An interior surface (206a, 206b) of a die mold (206) may be coated with a particle phase (22) (e.g., a ceramic-based material) and a molten metal matrix phase (20) (e.g., an aluminum-based material) may then be introduced into the die mold (206) such that a composite part (10) is formed with an exterior region (16) or outer layer that is particle-rich compared to an interior region (14).

An adjuster mechanism for a disc brake. The adjuster mechanism may include an outer piston and an inner piston. The outer piston may define a bore having a female thread, a non-threaded region, and a transition region. The non-threaded region may have a greater diameter than a minor diameter of the female thread. The minor diameter of the female thread in the transition region may progressively increase until it meets a major diameter of the female thread.

A hybrid torque tube for a brake assembly may comprise a tube portion having a centerline axis, and a conical back-leg portion extending from the tube portion. A stator spline may be formed on a radially outward surface of the tube portion. A foot may be formed on a radially inward surface of the tube portion. The tube portion is formed using a first manufacturing process and at least one of the conical back-leg, stator spline, or foot is formed using additive manufacturing.
