The Bendix+ EnduraSure+ is a high-performance double-diaphragm spring brake chamber designed for heavy-duty commercial vehicles, including both drum and air disc brake systems. It replaces the legacy EverSure+ series and is engineered to be the lightest weight chamber in its class. It offers a No Touch Power Spring - a proprietary design that prevents -coil clash- as well as superior durability and corrosion protection. The standard EnduraSure+ is an open-vented design intended for typical line-haul applications. The EnduraSure+-Pro is a sealed version designed for extreme longevity and severe environments.
