Abstract
A brake shoe structure which provides resiliency and increased lateral strength at at least one end of the table of a fabricated brake shoe. A portion of the web at that one end of the brake shoe is spaced inward from the radially inner surface of the table to provide a relief area to accommodate deformation of the table at that end of the brake shoe under dynamic braking conditions. The table at that end of the brake shoe extends longitudinally beyond the circumferential edge of the web where it is formed as a lip extending laterally across the table and radially inwardly to provide lateral strength to that end of the brake shoe table.
