A brake steering mechanism for a vehicle includes a vehicle body having a seat properly disposed at a preset area in opposition to a brake pedal and an acceleration pedal disposed at the front of the vehicle body thereof wherein a left and a right brake sticks are mounted to both lateral sides of the seat and linked to a left and a right brake components of a left and a right front wheels via a first and a second control wires respectively for controlling the movement of the left and right front wheels thereof respectively. A rear wheel with a rear brake component is disposed at the back of the vehicle body wherein the brake pedal is linked to the rear brake component thereof via a third control wire for controlling the movement of the rear wheel thereof. Thus, the vehicle body is easily turned to the left/right via the left/right brake sticks and doubly held in brake via the first, second, and third control wires thereof. Without holding stiffly onto a conventional steering wheel of a vehicle, a driver can drive comfortably with both hands placed naturally onto the left and right brake sticks by both sides of the seat thereof. Besides, with the conventional steering wheel removed there-from, the driver won't be blocked in view by the steering wheel so as to look straight ahead and see clearly the situations on the road to ensure the safety of driving.
