TREAD BRAKE ASSEMBLY ABSTRACT OF THE DISCLOSURE This invention relates to a pneumatically-applied spring- released brake assembly for each individual wheel of a railway vehicle truck, wherein the brake assembly comprises a pair of levers that so cooperate with non-self-locking threads formed on a nut and a screw member as to provide a high mechanical advantage or multiplication of the braking force transmitted from a piston to a brake shoe thereby enabling a substantial reduction in the diameter of the piston and therefore of the size of the brake assembly from that of such assemblies heretofore necessary to transmit the same braking force to the shoe.
