PURPOSE: A two-leading shoe type drum brake using one wheel cylinder is provided to increase braking force, by forming the both brake shoes to be leading shoes through only one wheel cylinder. CONSTITUTION: One end of one brake shoe(21a) is connected to a wheel cylinder(22) and the other end is fixed to an anchor plate(23a). One end of the other brake shoe, is connected with the wheel cylinder, is fixed to an anchor plate(23b) and the other end is connected to the first arm(24b) of a support plate(24). The other arm(24a) of the support plate(24) supports the one end of one brake shoe(21a). A return spring(25) restores the brake shoes when a braking is released, and is fixed between the brake shoes and the other arm of the support plate.
