A brake control system and method controls a braking operation in a vehicle. When a pressure sensor and a stroke sensor are functioning normally, a brake control system calculates a final target deceleration Gt as a weighted sum of a target deceleration Gpt that is based on a master cylinder pressure Pm and a target deceleration Gst that is based on a depression stroke St, and a braking force is controlled based on the final target deceleration Gt. On the other hand, when there is an abnormality in the stroke sensor, the brake control system calculates a target deceleration Gpt that is greater than when the stroke sensor is functioning normally in a region where the braking amount is small, and the target deceleration Gpt is set to the final target deceleration Gt. When there is an abnormality in the pressure sensor, the brake control system calculates a target deceleration Gst that is larger than when the pressure sensor is functioning normally in a range where the braking amount is large, and the target deceleration Gst is set to the final target deceleration Gt.
