The trailing brake pad abutment may have a trailing wall surface and a trailing floor surface, at least one of which may be machined.

A brake pad assembly having a consolidated lining comprised of an enhancement framework disposed within a tribological lining, the enhancement framework and tribological lining having substantially the same compressibility factor. The enhancement framework or tribological lining may advantageously be manufactured using an additive manufacturing technique.

A disc brake having at least one brake pad, a brake caliper, an actuation mechanism, and a brake pad support structure. The brake pad has a moveable pad retainer formation to permit assembly and retention of the brake pad in the brake pad support structure such that the brake pad is held for operation of the disc brake.

Disclosed are a brake disk and a method for manufacturing the same. In particular, the brake disk may include a friction surface formed of cast iron, and the friction surface of the brake disk is divided into a plurality of sections in a circumferential direction. Preferably, an average of the numbers per unit area of eutectic cells formed on surfaces of the sections may not be greater than 300 ea/cm.sup.2.

A disc brake rotor for a vehicle is provided. The disc brake rotor includes a hat and a friction ring extending circumferentially from the hat. The disc brake rotor is formed of a cast hypereutectic aluminum alloy. The hypereutectic aluminum alloy includes: 14.00 to 25.00 wt. % of silicon; 4.90 to 8.00 wt. % of copper; 0.05 to 0.90 wt. % of nickel; 0.50 to 1.50 wt. % of magnesium; 0.05 to 1.20 wt. % of iron; 0.05 to 1.00 wt. % of manganese; 0.05 to 1.00 wt. % of zinc; 0.05 to 1.20 wt. % of titanium; 0.05 to 1.20 wt. % of zirconium; 0.05 to 1.20 wt. % of vanadium; 0.001 to 0.10 wt. % of phosphorous; and the balance aluminum. The alloy may also include other trace elements such as chromium, lead, and tin in an amount not exceeding 0.20 wt. %. The disc brake rotor may be formed by a high pressure, semi-solid die casting process including rheocasting.

A method of manufacturing a brake disc of heterogeneous materials, may include a disc device and a hub device formed in a cast-bonding manner using different materials, includes performing a first casting for casting the disc device using a grey cast-iron material, performing a preparation step by placing the disc device in a casting mold as an insert, performing a second casting for preparing a brake disc cast product by injecting molten aluminum alloy into the casting mold and casting the hub device to be cast-bonded to the disc device, and performing an oxynitriding process for forming an oxynitride layer by smoothing a surface of the brake disc cast product and performing heat treatment in a gaseous atmosphere at a temperature ranging from 425 to 500 C.

An universal joint configured to transfer rotational movement from a first shaft to a second shaft at an angle and method of manufacturing the same.

A disc brake caliper (1) comprises a caliper body (2) and a pair of pads (20) and, in each side portion (2a,2b) of the caliper body (2), a distal piston (22a) and a proximal piston (22b), having radially distanced and aligned pressure centers (22a,22b).

Provided is a disc brake which solves, with a simple structure, the issue of interference between a carrier and an electric motor. A carder 3 applied to the disc brake includes a recess 28 in one arm 18 of the pair of arms 18 and 19 which recess is casted so as to be recessed in a direction toward a line, which is parallel to a tangent line L3 tangent to an the pin hole boss 16 on one side and perpendicular to a line segment L1 connecting centers of the pair of pin holes (pin hole bosses 16, 16) and extends through the center of the pin hole on the one side, with respect to the tangent line L3. This makes it possible to prevent or reduce the interference between the carrier 3 and the electric motor, with a simple structure.

The present application discloses a ceramic preform, a method of making a ceramic preform, a MMC comprising a ceramic preform, and a method of making a MMC. The method of making a ceramic preform generally comprises preparing reinforcing fibers, preparing a ceramic compound, and forming the compound into a desired shape to create the ceramic preform. In certain embodiments, the ceramic compound is formed as either a disc or a ring for use in a brake disc metal matrix composite. The metal matrix composite generally comprises the ceramic preform infiltrated with a molten metal to form the brake disc metal matrix composite. The method of making the metal matrix composite generally comprises heating the ceramic preform, placing the ceramic preform in a mold cavity of a die cast mold, and introducing molten metal into the mold cavity to infiltrate the ceramic preform to form the brake disc metal matrix composite.
