A wheel cylinder fixed to a back plate and operated by brake fluid pressure from a mask cylinder, a pair of piston members arranged in a brake fluid pressure chamber of the wheel cylinder, and a pair of piston members provided in the piston member to supply brake fluid pressure. A drum brake comprising: a brake shoe that is pressed against the inner surface of the brake drum; and a parking brake mechanism that mechanically presses the brake shoe against the inner surface of the brake drum by operating the parking brake; and a piston member of the wheel cylinder. A drum brake characterized in that the drum brake is provided with a biasing means for biasing the drum brakes toward each other.
