Abstract
A cam for a brake is provided that allows for greater brake shoe travel and thicker brake linings while providing the same or greater mechanical force as compared to conventional cams. One or more lobes of the cam include multiple portions having varying profiles in axial cross-section. The variation in the cam profiles results in a cam in which the outermost ends or tips of the lobes are longer than in conventional cams yet retain the same mechanical strength.
