(54)	Brake button/spring assembly and related method

(57) A tape cartridge brake button/spring assembly (57) and related method are described. The brake button (60) includes a set of tabs radially opposed on the underside thereof. These tabs direct, center and maintain the spring (62) relative to the brake button (60) to facilitate automated assembly and prevent the spring (62) from becoming misaligned in the cartridge (55) during assembly or use. In addition, the brake button (60) includes a cross-shaped recess for receiving a correspondingly shaped projection (75) formed on the lower half of the cartridge (55) to facilitate assembly and prevent binding of the brake button (60).
