Hendrickson A-23039 or A23039 is a Type 12 standard stroke spring and service brake chamber assembly. Two chambers share one unit: the service side applies the brakes with air, and the spring side applies them mechanically for parking and emergency stops. Air pressure holds the spring compressed while the truck is driven, and when that pressure is exhausted the spring applies the brake instead. Corrosion or physical damage is a safety concern, since the loaded spring can release suddenly, so a damaged chamber should be replaced rather than repaired.
