It attaches to the brake camshaft and automatically maintains the correct clearance between the brake lining and drum each time the brakes are applied, ensuring consistent braking performance and reducing manual adjustments. It fits a 1.5-inch diameter camshaft with 10 splines and has a straight arm adjustable between 5.5 and 6.5 inches center-to-center. This part is typically replaced when the slack adjuster fails to self-adjust or becomes worn.
