In the conventional technology of stopping a hill, when the driver presses a brake, hydraulic pressure is generated by this stepping force, and the generated hydraulic pressure causes the brake pad to closely adhere to the disk, thereby affecting the friction force between the disk and the pad. The brakes were generated, and the braking allowed the vehicle to stop, and the driver had to keep on applying the brakes when the hill was stopped.
