The present invention is directed to a braking control system for controlling a braking force applied to each of front and rear wheels of a four-wheel drive vehicle, which has a front differential gear connected to the front wheels, a rear differential gear connected to the rear wheels, and a center differential gear connected to the front and rear differential gears. A wheel speed sensor is provided for detecting wheel speeds of the wheels. A non-contact detector is provided for determining whether at least one wheel is not contacting the ground in the vehicle's path, on the basis of the wheel speeds detected by the wheel sensor. A downhill detector is provided for determining whether the vehicle's path is on a downhill road. An engine brake detector is provided for determining whether the vehicle is under an engine brake. And, a braking force controlling device is provided for controlling a braking force applied to each of the wheels independently, and adapted to apply the braking force to at least one of the wheels, when the downhill detector determines that the vehicle's path is on the downhill road, the engine brake detector determines that the vehicle is under the engine brake, and the non-contact detector determines that the at least one wheel is not contacting the ground.
