PROBLEM TO BE SOLVED: To provide a disc brake control system for a vehicle, which eliminates "drag" of a brake pad generated after a brake disc is restored from a thermal collapsing condition. SOLUTION: In this device, when the brake disc temperature exceeds a value T1, it is determined that "the brake disc D is in the condition of thermal collapsing," and when the temperature of the brake disc D in the thermal collapsing condition is below a value T2 (< the value T1), it is determined that "the brake disc D is restored from the thermal collapsing condition (condition of restoration from thermal collapsing)." At predetermined timing after it is determined that "the brake disc D is in the condition of restoration from thermal collapsing," minute liquid pressure is applied to all wheel cylinders independently of brake pedal operation by an operator, only for predetermined short time. Due to this, after the minute liquid pressure is released, an inner pad Pin and an outer pad Pout with respect to the brake disc D are returned to normal positions, and "drag" of the inner pad Pin generated in the "condition of restoration from thermal collapsing" is eliminated.
