Narrative:
After gear extension; just prior to the FAF; [we received] ECAM system failure alert; brakes autobrk fault. Inoperative systems; according to ECAM; were normal brakes and autobrakes. Approach was discontinued [and the] missed approach procedure executed. Altitude was approximately 2;500 ft MSL. Vectors [were] requested and received from tower and approach control to allow us time to analyze situation and coordinate with company. Emergency [was] declared [and] all SOP actions completed as well as FM procedures. [We] returned for an uneventful landing. System error cleared itself upon second gear extension. The decision was made to taxi the aircraft away from active runway and receive tow to gate. This occurred without incident. No further issues or concerns arose.
