As a result of severe shock and vibrations, the brake spiders on the involved vehicles may develop cracks near the camshaft mounting boss. The crack propagates across the spider until the camshaft boss is completely severed from the remainder of the spider. When the camshaft boss has completely severed, the s-cam, s-cam bracket, air chamber and slack adjuster can fall away from the brake spider resulting in a "no brake" condition on the wheel.
