Narrative:

Upon initial power advancement (very low speed); aircraft pulled strongly to the left and was difficult to control. Captain initiated abort. Returned to gate for maintenance inspection. Left main gear reached a maximum of 380 degrees C; while right main gear reached a maximum temperature of only 75 degrees C. Dragging brake suspected. Brake and steering control unit reset; brakes bled; in addition to other diagnostic tests; and brakes operated to crew's satisfaction. Close attention was paid to temps/pulling tendencies on the taxi out. Flight continued with no further incident.

Title: A320 Captain reports aircraft pulling strongly to the left as takeoff is commenced. Crew rejects and returns for maintenance. Hot brakes on the left side are noted. Brake and steering control unit reset and brake bleed apparently solved the problem.
