ABSTRACT:
A bonded composition type railroad brake shoe is disclosed in which the keybridge cavity of the brake shoe backing plate is filled with composition brake lining material for reinforcement and dampening of the keybridge. An insert located in the keybridge cavity comprises a pair of spaced-apart ribs that are upturned from a base plate such that the insert partitions the keybridge cavity. The insert is bonded in place by the composition brake lining material, which is formed with a keyway by the insert. The insert further serves to reinforce the keybridge in conjunction with the composition brake lining material therein.
