A redundant emergency/park power source brake system is disclosed. The brake system comprises a first brake control module (310A) having a first shut-off valve (312A) in fluid communication with an outboard servo-valve (314) and a second brake control module (300B) comprising a second shut-off valve (310B) in fluid communication with an inboard servo-valve (316). A first emergency/park power source (302) is in fluid communication with the first shut-off valve and a second emergency/park power source (302B) is in fluid communication with the second shut-off valve. The brake system also comprises a vehicle management system (286) in electronic communication with the first and second brake control modules. The first brake control module is configured to receive a first signal comprising at least one of a VMS signal, a park value or an emergency value, wherein in response to receiving the signal, the OBSV may be configured to at least partially open. The second brake control module is configured to receive a second signal comprising at least one of the VMS signal, the park value or the emergency value, wherein, in response to receiving the signal, the IBSV may be configured to at least partially open.
