ABSTRACT:
A brake rigging for a railway vehicle having a singular truck-mounted brake apparatus for generating a braking force and a plurality of disk caliper assemblies for applying the braking force to each wheel. Wedge-like elements are rigidly attached to the braking beams of the truck-mounted brake apparatus and engage a pair of rollers that are pivotably mounted on corresponding ends of a pair of pivoted levers disposed within a disk caliper assembly. The wedge-like elements transmit a generated braking force to the levers, the rocking of which in opposite directions is effective to force the brake shoes against the respective opposite sides of a disc brake rotor to exert the braking force thereon.
