Manual Brake Adjuster Failure Analysis


Manual slack adjuster should be inspected for gear set wear. To do this, back off the adjusting hex until all spring pressure is relieved from the clevis. Work the adjusting nut 1⁄4 turn back and forth while watching for clam rotating. If you have 1⁄8 to 1⁄4 turn of play without the cam rotating, the manual brake should be replaced. Repeat this procedure every 1⁄4 turn of the adjusting nut to check the whole gear set.


Self-Adjusting Brake Adjuster Failure Analysis


If the power stroke is at or more than the maximum stroke, measure free stroke to determine if the slack adjuster is operational.
