Abstract
An improved brake shoe table includes the edges of the brake shoe table being bent radially inwardly relative to the remainder of the table by between 45 and 90 degrees. The bent edges increase the rigidity of the brake shoe and also reduce localized lining wear by bringing the lining into contact with a brake drum in a more uniform fashion. Moreover, the improved brake shoe design has unexpectedly decreased the operation noise associated with the use of a cam brake system.
