Saudi Arabian Airlines flight SV115, a Boeing 777-200ER, was parked on Stand 319, with the parking brake set and the passengers disembarking, when the aircraft began to roll backwards. Pressure in the parking brake system had dissipated causing a loss of brake application. The right hydraulic system AC electric pump was activated and this reinstated the hydraulic brake pressure, which brought the aircraft to a stop. A failure of the parking brake valve was identified as the cause of the loss of hydraulic pressure in the parking brake system.
