Narrative:
Just after leveling at cruise altitude FL390 the right hydraulic system pressure light and the brake source light illuminated. The psi read out for all three systems was normal and there appeared to be no other indications of a system pressure loss. The captain made the decision to return to our departure airport; an emergency was declared and center vectored us directly to the airport. The appropriate checklist in the QRH was completed and the descent and arrival and landing were uneventful. After we had turned off the runway we stopped and requested 'crash; fire and rescue' team to inspect the aircraft. Nothing unsafe was noted and we proceeded to the gate. The passengers were disembarked without incident and maintenance took charge of the aircraft.
