A core pattern reformer system for adjusting and setting a core pattern for use in casting a gas turbine blade has a first portion having a first internal face with a concave portion. The first portion is coupled to a second portion. The second portion has a second internal face with a convex portion. A plurality of adjustable pins is positioned along the internal faces of the first portion and the second portion. The pins have a height that is adjustable with respect to the internal faces. A locking mechanism is included for securing the first portion to the second portion. The system includes one or more air inlets and one or more air exits and a source of cooling air coupled to the one or more air inlets.

A brake carrier is provided for a disc brake having at least one brake pad, wherein the brake carrier includes: a wrap-around disc holder that wraps around a section of a brake disc of the disc brake in a frame-like manner; at least one brake pad slot in which the brake carrier guides the at least one brake pad, wherein the at least one pad slot is formed by carrier lugs, support surfaces and bridge struts on the wrap-around disc holder. The brake carrier is produced as a single piece using a shaping method and has a mold partition burr. The mold partition burr is arranged outside of the wrap-around disc holder.
