A brake disk with a friction ring or to a friction ring, which comprises a PMMC (particle metal matrix composite), at least in the region of its friction surface. The friction surface of the friction ring is provided with mechanically applied microgrooves, which extend in a radial direction with respect to a circumferential direction of rotation of the friction ring, non-tangentially angled thereto.

The present disclosure relates to a hybrid lightweight brake disk and a method for producing the hybrid lightweight brake disk. The hybrid lightweight brake disk includes a brake chamber and a friction ring with at least one circular, outer friction surface. The method provides a brake chamber that includes a material containing an aluminum-forged alloy and a friction ring having a rapidly solidified aluminum alloy built up on an edge region of the brake chamber by using a laser deposition welding process or a 3D-printing process.

A method comprising the steps of: (a) forming one or more friction materials of a brake pad; and (b) inspecting each of the one or more friction materials with one or more ultrasonic testers while each of the one or more friction materials are within a manufacturing line to determine if each of the one or more friction materials meet one or more desired material properties.

A method for making a friction plate that includes a core plate and a friction facing is disclosed. The method includes cutting a pattern of friction material segments into a friction material sheet such that each friction material segment remains integrally connected to the friction material sheet, locating a predetermined number of the friction material segments adjacent to a surface of a core plate to which a bonding material is present, separating the friction material segments from the friction material sheet, and placing the friction material segments onto the surface of the core plate over the bonding material. An apparatus for practicing this method is also disclosed.
