[0031] In this embodiment, when the vehicle brakes, the brake pedal is depressed, and the rear cylinder piston of the brake cylinder is pushed forward by the transmission rod. The forward movement of the rear cylinder piston causes the front cylinder piston of the brake cylinder to move, thereby compressing the brake fluid in the brake cylinder and increasing the brake fluid pressure.
