This is a Type 30/30 spring brake chamber with a long push rod, used on heavy-duty trailer air brake systems.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It combines a service brake (air applied) and a parking/emergency brake (large spring applied). The long-rod design provides extra reach for axles that need extended push rod length. It should be replaced if you notice air leaks from the chamber, weak parking brake hold, or physical damage.
