A device for cooling brake fluid in a brake operating unit which comprises first and second flow channels having respective one ends connected to a cylinder of a brake element. The brake fluid circulates in the cylinder using both of the first and second flow channels by repetition of applying and releasing the brakes. As a result, it is possible to provide a device for cooling a brake fluid, wherein vapor-lock can be presented with certainty, the brake element that is a drum brake or a disc brake is improved in safety and reliability, friction materials such as brake shoes or pads are restrained from rising in temperature and a fade phenomenon is also reduced so that a stable braking operation can be obtained.
