A disk brake disk has a bell made of a first material and a braking band made of a second material. The bell has a bell body having a radially outer bell body portion and forms a plurality of bell projections radially protruding from the radially outer bell body portion. Each bell projection has a projection base close to the radially outer bell body portion and a distal projection portion far from the radially outer bell body portion. A braking band body is coupled to the distal projection portion. Adjacent projection bases are joined to one another by a bell rib made in a single piece with the bell body and having an inner axial rib face and an outer axial rib face. The braking band body is coupled to the inner axial rib face, leaving the outer axial rib face free and externally facing the disk brake disk.

The present disclosure relates to a brake disc including a braking part having a circular plate shape having a hollow portion and a plurality of coupling portions protruding and extending from an inner diameter surface thereof, and a hat part disposed in the hollow portion and having a plurality of insertion portions protruding laterally, in which the plurality of coupling portions is respectively coupled to the plurality of insertion portions, and the coupling portion of the braking part and the insertion portion of the hat part are joined to only one of an outboard portion or an inboard portion of the braking part. According to the present disclosure, it is possible to reduce noise occurring at a position at which the hat part and the braking part are coupled to each other and improve cooling performance.

A disc brake caliper has a caliper body and a pair of pads and, in each side portion of the caliper body, a distal piston and a proximal piston, having radially distanced and aligned pressure centers.

An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting an inner and outer brake pad and a brake rotor having a disk, and a hat, and wherein the hat is bolted to the wheel. A hydraulic cylinder is adapted to push the inner brake pads into the disk surface, causing the floating caliper to move bringing the outer brake pad into contact with the disk. Finally, the rotor is made such that a complete 100 kilometer per hour, 0.9 gross vehicle weight braking causes the disk to expand in thickness by at least 0.15 mm and to cool to shrink in thickness, relative to its expanded thickness, by at least 0.1 mm within 60 seconds of the cessation of braking, in an ambient temperature of less than 30° C.

A brake caliper adapted for use in a vehicle disc brake assembly and method and apparatus for producing the same. The apparatus for producing the brake caliper comprises a mold member and a core member. The mold member has two mold sections meeting at a vertical interface, the first mold section having an extension from the vertical interface into the second mold section to form an integrally cast lug on the brake caliper. The core member has three extensions operative to form three integrally cast locating surfaces on the cast brake caliper, the extensions defining datum surfaces for subsequent machining of the cast brake caliper to predetermined tolerances using the three locating surfaces as the datum surfaces.

An exemplary method for making a metal matrix composite vehicle component includes: using a mold including male and female die portions having mold surfaces and a plurality of spacers; heating the mold to a casting temperature; placing a ceramic preform on the plurality of spacers, the ceramic preform being spaced apart from at least one of the mold surfaces by the spacers; closing the mold to form a mold cavity between the mold surfaces of the male and female die portions, the ceramic preform being disposed within the mold cavity; providing molten metal into the mold cavity; and pressurizing the molten metal to a casting pressure for a casting duration to infiltrate the ceramic preform thereby forming the metal matrix composite vehicle component.
