Zusammenfassung:	The utility model relates to the technical field of brake bottom plates, in particular to a novel brake bottom plate which is an olive-shaped integrated casting and comprises a fixing disc in the middle, a brake shoe shaft mounting hole in the lower side and a driving shaft mounting hole in the upper side, a round spigot is formed in the center of the fixing disc, the left side and the right side of the fixing disc are arc-shaped edges, and the left side and the right side of the fixing disc are arc-shaped edges. The radius of the arc-shaped edge is larger than the distance between the circle center of the circular seam allowance and the arc-shaped edge. According to the brake bottom plate, the weight of the brake bottom plate is reduced, and after the brake bottom plate is assembled with the brake shoe, the inner arc plate of the brake shoe is arranged on the outer side of the arc-shaped edge, so that the potential interference hazard possibly existing between the brake shoe and the brake bottom plate during
