At cruise altitude; just prior to T/D; we received ECAM 'WHEEL N/W STRG FAULT' followed shortly after by 'BRAKES SYS 2 FAULT'; neither of which had an ECAM procedure.  I therefore asked the First Officer to reference the QRH; both of which had a QRH procedure.   There was no airborne procedure for the WHEEL N/W STRG FAULT.  We did apply the QRH procedure for BRAKES SYS 2 FAULT; but as soon as BRAKES SYS 2 FAULT cleared; we got a 'BRAKES SYS 1 FAULT' ECAM.I transferred aircraft control to the First Officer; and also delegated the radios to him.  I made voice contact with NAME via ACARS *call me request.  Dispatch got Maintenance Control and an Operations representative on the call.  I discussed the nature of the failure with all parties and after discussing continuing to ZZZ or diverting to either ZZZ1; ZZZ2; or ZZZ3; decide the safest choice considering runway length; weather; and emergency resources was a diversion to ZZZ3.Dispatch gave us fuel burn to and landing data at ZZZ3.  They also notified the station and arranged resources.I briefed the First Officer what transpired and decided to have him remain Pilot Flying.  I notified ATC of the diversion and advised ATC.The First Officer made a normal landing.  We landed uneventfully; came to a stop on center line; and the emergency vehicles approached the aircraft and have the all-clear for us to be towed off the runway to the gate.
A320 Captain reported Brake Sys 1 and 2; plus N/W steering fault ECAM messages in flight and elected to divert and make a precautionary landing.
