It connects the brake chamber push rod to the S‑cam shaft and automatically takes up clearance as the brake shoes wear, keeping brake stroke consistent and braking responsive without manual adjustments. You replace it when the adjuster seizes, fails to auto-adjust, or develops excessive free play due to internal wear, which can compromise braking performance.
