Narrative:

The aircraft dispatched with MEL 2911k (right hydraulic demand pump inoperative in auto; operate in 'on' for all phases of flight). At cruise we had an intermittent brake source light; followed by an right sys hyd press light; mc light; and EICAS message. We advised ATC we had a hyd system problem and needed to consult with company. I had the [relief pilot] return to the flight deck to assist. We completed the QRH 130.14 (right hydraulic system press) we [requested priority handling]. After discussion with dispatch; [technical support maintenance control]; [company communications system] we diverted back to ZZZ. We elected to burn fuel vs dump to get to a max landing weight 320 lbs.; I advised the purser and cabin crew of our decision to return to ZZZ using 'test' SOP. I notified the passengers of our problem and our decision to return to ZZZ due to safety. We completed all checklist and procedures and reviewed the approach and landing with the non-normal landing distance. Dispatch coordinated with station operations for aircraft recovery and sent a diversion flight plan. Normal approach and landing runway xxl. We taxied to the end and turned off the runway to meet the [aircraft rescue and firefighting] vehicles. After stopping we got hot brakes (on brakes 3; 4; 7; 8) due to the loss of sub-systems associated with the right hydraulic system i.e. Autobrakes; right TR and some spoilers we completed the hot brakes checklist (at our weight and break application speed we were in the caution zone); we chocked the gear to let the brakes cool to prevent fuse plug melting and brake fire. We coordinated with [aircraft rescue and firefighting]; station operations; maintenance to send a recovery team to tow the aircraft to the gate. We elected to keep the passengers on the aircraft and recovered the aircraft to gate. After completing parking checklist I advised the passengers cs would coordinated recovery and continuation plans and explained the problem and thanked them for their patience. After deplaning the passengers the entire crew did a safety debrief. I debriefed [aircraft rescue and firefighting]; station maintenance; dispatch; [chief pilot]. Outstanding job by all! Thanks to dispatch; flight crew; cabin crew; ATC; and ZZZ [aircraft rescue and firefighting]!
