The invention relates to the technical field of wagons, in particular to a light-weight anti-misloading brake lever, which comprises a lever body and three bushes, wherein the bushes are arranged at the two ends and in the middle of the lever body respectively; one end of the lever body is thicker than the other end of the lever body, and the thicker end is symmetric in a thickness direction; and the lever body is provided with a weight reducing groove. According to the light-weight anti-misloading brake lever provided by the invention, the weight of the brake lever can be reduced, misloading of a force arm of the lever is prevented, vehicle braking force is consistent with a design requirement, and relieving resistance after vehicle braking is reduced; and moreover, the installation height of the brake lever can be kept consistent with the center of a piston of a brake cylinder, so that the stress of the brake lever is more reasonable.
