This is a Type 30/30 piggyback brake chamber that combines air-operated service braking and spring-actuated parking/emergency braking in one unit.
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.
The 'long shaft' or long‑stroke design provides extra push rod travel, which helps compensate for brake lining wear and maintains proper adjustment on heavy‑duty trucks and trailers. It is normally replaced when the internal diaphragm fails, the spring loses tension, or the push rod stroke exceeds the legal limit.
