The TR3030CLS-WC is a long-stroke combination spring brake chamber (Type 30/30) with a welded clevis. It merges the service brake chamber and the parking/emergency spring brake into a single unit, delivering longer pushrod travel than standard chambers—ideal for upgrading older drum brake systems or replacing worn chambers on heavy-duty trucks and trailers. When the brake pedal is used, the service side applies the brakes; when parked, a powerful spring holds them. You typically replace these when you notice air leaks, reduced braking force, or physical damage to the housing.
