ABSTRACT:
A drum brake (10) includes a backing plate (11) supporting a pair of drum brake shoes ( 12, 14) having brake shoe webs (16, 18). An opposing pair of brake shoe ends (26, 28) have adjacent thereto a combination drum brake shoe hold-down bracket and cable guide (60) attached to the backing plate (11) . The hold-down bracket and cable guide (60) has a pair of securement portions (61) extending laterally or transversely, via axial projections (62) and ends (64) , relative to the center of revolution (A) of the drum brake (10) and which engage the drum brake shoe webs (16, 18) to assist in maintaining the brake shoes (12, 14) in operative position. Each portion (61) of the hold-down bracket and cable guide (60) extends laterally toward one another via an axially extending portion (65) that curves in an annular path to form a center portion (67) that defines a cable guide path (68). A parking brake cable assembly (40) is captured within the cable guide path (68) so that it will not interfere with other brake components. The brake shoe hold-down bracket and cable guide (60) provides a positive method for preventing the brake shoes (12, 14) from lifting off the backing plate (11) and guiding the parking brake cable assembly (40).
