Narrative:

Frequency/altitude: ny FL330. ATC facility: ZMA. Location: approximately 150 mi northeast mia. As PF, had leveled at cruise altitude when observed hpsov message on EICAS. Consulted with OM, MEL, dispatch, tulsa technician, and agreed should return to mia for landing. Since no dump system installed, and WX and conditions at mia were good, elected to do an overweight landing. Made PA to passenger, and coordinated possible resulting emergencys. Declared an emergency due to overweight landing, and arranged for mia crash fire rescue equipment to assist after landing. Landed on longest runway, 25 degree flaps, and managed a smooth touchdown. Used reversing and minimal braking. After turnoff, requested crash fire rescue equipment to examine wheels. Reported cold brakes. As a precaution, requested crash fire rescue equipment to follow to gate. Back in gate great team crew.
