It automatically adjusts the clearance between the brake shoes and drum as the linings wear, maintaining proper brake stroke and reducing the need for manual adjustment. This unit has a 6-inch arm length, a 1-1/2 inch diameter input shaft with 28 splines, and is built to the Meritor pattern. Replace it if the existing adjuster fails to maintain brake adjustment, shows excessive free play, or is physically damaged.
