INTEGRATED DISC BRAKE AND DRUM BRAKE CONSTRUCTION ABSTRACT OF THE DISCLOSURE The present invention comprises an integrated disc brake (50) and drum brake (120) construction. A support member (12) is supported by a vehicle axle (14) and extends radially outwardly to provide support for a housing (52) of the disc brake (50). The housing (52) is secured by bolts (93 or 94) to the support member (12), the housing (52) having through openings (54) for receiv- ing rod members (75). The rod members (75) each have one end (76) secured to the support member (12) and a second part (90) and the other end has an opening (77) for an internal bore (78) extending therein. The disc brake (50) includes an axially movable yoke (60) attached to guide pins (82) extending into bores (78) of the rods (75) for slidable movement therein. The second part (90) extends radially to provide support for an inner brake pad (20) and may extend axially away from the housing (52) to provide an anchor support (91) for shoulders (132, 142) of drum brake shoes (130, 140). The support member (12) supports a mechanical actuator (121) which may be operated to bias the drum brake shoes (130, 140) into engagement with a drum portion (42) of the brake disc (40) in order to effect a parking brake operation.
