Narrative:

During climb-out and passing 10;000 AGL we received two EICAS messages. 1) brake source and 2) anti-skin inoperative. We completed the associated checklist for these items and then noticed that the action taken during their performance that the right hydraulic electric pump had failed. I coordinated with dispatch for a return to the departure airport. We declared an emergency and returned for an uneventful landing. Landing weight was approximately 196.6 which is below max landing weight. Touchdown was normal and on speed. Reverse thrust was applied with no brakes until approximately 60 KTS. Brakes were then applied with one steady application. A full stop was made and the emergency crew verified our brake temperatures were normal. I parked the brakes and had maintenance tow the aircraft to the gate. This aircraft had previous write-ups for the brake source light.
