AUTO SLACK ADJUSTER

This Haldex automatic slack adjuster maintains proper clearance between the brake shoes and drum on heavy-duty truck and trailer air brake systems. As brake linings wear, it automatically adjusts to keep braking consistent and safe, eliminating manual adjustments. Replacing a seized or worn adjuster helps prevent brake imbalance, reduces stopping distances, and avoids inspection failures.
