<p>A method of cooling a brake fluid using a brake operating unit which comprises a first and a second flow channels (2, 3) connected to a cylinder (1 or 20; 1 or 20; 20 or 1; 1 or 20) of a brake element at one ends thereof comprises a step of setting the absolute value of a difference between the amount of brake fluid supplied to and that discharged from the cylinders (1 or 20; 1 or 20; 20 or 1; 1 or 20) in the first flow channel (2) to apply and release brakes respectively equal to the absolute value of a difference between the amount of the brake fluid supplied to and that discharged from the cylinder (1 or 20; 1 or 20; 20 or 1; 1 or 20) in the second flow channel (3) to apply and release the brakes respectively, so as to circulate the brake fluid in the cylinder (1 or 20; 1 or 20; 20 or 1; 1 or 20) using both of the first and second flow channels (2, 3) by repetition of applying and releasing the brakes. As a result, it is possible to provide a method of and a device for cooling a brake fluid, wherein vapor-lock can be prevented 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. <IMAGE></p> |
