A method includes heating a brazing material (32) in a braze chamber (20) of a first component (10) to a braze temperature to melt the brazing material (32). The brazing material (32) flows from the braze chamber (20), through at least one internal channel (22) of the first component (10), and into a braze gap (18) between the first component (10) and a second component (16) to braze the first component (10) to the second component (16). In a further aspect, a brazed article (40) includes a first component (10) having a braze chamber (20) and at least one internal channel (22) extending from the braze chamber (20) to an external surface (12), a second component (16) having at least one braze surface (14) separated from the external surface (12) of the first component (10) by a braze gap (18), and a braze material (42) in the braze gap (18). Further, a braze assembly (30) includes a first component (10), a second component (16), and a brazing material (32) in the braze chamber (20).
