Abstract
A composition type brake shoe for a railroad car in which the backing plate keybridge is filled with composition brake lining material to reinforce the keybridge. A recess formed in the braking face of the brake lining extends beyond the keybridge so that a relatively thin area of brake lining is formed between the recess and backing plate outboard of the keybridge opening, and to which thin section area cracks that may develop in the brake lining are encouraged to migrate in order to redirect backing plate flexure away from the critical keybridge area to a stronger area of the backing plate.
