    摘要: A sash balance brake shoe assembly (2) is disclosed for counterbalancing a sash window (3) slidably supported within a master frame (5). The assembly generally includes a balance assembly preferably in the form of a block and tackle balance assembly (7) and a brake shoe (28). The balance assembly has a balance channel (6). The brake shoe (28) has an extension member (36) that is received by the balance channel (6). A fastener (42) directly connects the brake shoe (28) to the balance channel (6).
