Abstract
A railway brake shoe including a first layer constructed of a composition friction material and a second layer constructed of a resilient composition material. The second layer is joined to the first layer. The second layer is adapted to receive at least one mechanical fastener therein to removably secure the brake shoe to a brake head. The resilient material of the second layer is capable of applying a circumferentially compressive force to the at least one mechanical fastener and prevent breakage of the composition friction material at the attachment location and/or enlargement of the attachment apertures due to vibration and lateral impacts.
