A320 flight crew accepts an aircraft after a bscu change and during climb passing 7;000 feet brk system 2 fault and brk automatic brk failure ECAM's annunciated. Status page indicates norm brk; automatic brk; brk system 2 have faults and the crew elects to return to the departure airport. After landing braking is via alternate brakes and the nose wheel steering is functional.

Narrative:
While climbing out on the departure; brake: system 2 fault appeared. As we continued to climb and began to comply with procedures; brake: automatic brake fault appeared. The captain elected to remain in us air space and hold as we began discussing problem with dispatch and maintenance control. The captain kept flight attendants informed. Of particular interest was the status page which indicated the following 4 inoperative items: CAT 3 dual; normal brakes; auto brakes and brake sys 2. We were puzzled by normal brakes being inoperative given that only brake sys fault 2 was on the upper ECAM. Maintenance control could not decipher why we had that indication. If normal brakes were inoperative; shouldn't we also have a brake system 1 fault? We elected to return; declare an emergency and operate under the assumption that we would decelerate with alternate brakes. We landed without incident using alternate brakes. I monitored and called out pressures from the triple brake indicator as the captain decelerated. NWS worked so we taxied to the gate.

Narrative: While climbing out on the departure; BRAKE: SYS 2 FAULT appeared. As we continued to climb and began to comply with procedures; BRAKE: AUTO BRAKE FAULT appeared. The captain elected to remain in US air space and hold as we began discussing problem with Dispatch and Maintenance Control. The Captain kept flight attendants informed. Of particular interest was the status page which indicated the following 4 inoperative items: CAT 3 DUAL; Normal Brakes; Auto Brakes and Brake Sys 2. We were puzzled by Normal Brakes being inoperative given that only Brake Sys Fault 2 was on the upper ECAM. Maintenance Control could not decipher why we had that indication. If normal brakes were inoperative; shouldn't we also have a BRAKE SYS 1 FAULT? We elected to return; declare an emergency and operate under the assumption that we would decelerate with ALTERNATE brakes. We landed without incident using ALTERNATE brakes. I monitored and called out pressures from the triple brake indicator as the Captain decelerated. NWS worked so we taxied to the gate.
