車両用ドラムブレーキ。 A back plate fixed to the vehicle body, a pair of brake shoes swingably supported by the back plate, an anchor block that supports the lower ends of both brake shoes, and the upper ends of both brake shoes. In a vehicle drum brake equipped with a wheel cylinder that presses a friction member against the brake drum by expanding the brake drum, a rotating brake member is provided between the leading brake shoe of both brake shoes and the anchor block. A drum brake for a vehicle, characterized in that a separating means is provided for separating the friction member of the brake shoe located on the downstream side of the brake drum from the brake drum when the brake is operated.
