The present invention relates to a braking device for a stroller which provides the braking function on both rear wheels synchronously. The present invention utilizes a pedal which can swing left and right to carry a rotary cam mechanism. Then the pedal will convert the swinging motion to a linear back and forth motion on the left and right braking rods. To step on the pedal is to control the motion of left and right braking rods. The left and right braking rods will be carried by the pedal to brake or release these two wheels. The pedal further has a holding mechanism for keeping the pedal in a braked or released position.
