36Spring Brakes and Parts CATALOG NUMBER 36 www.midwestwheel.com Order NLINE ™ www.midwestwheel.com Order NLINE ™ You rely on your spring brakes to stop and park your vehicles with confidence, every time. But when contaminants enter the chamber, corrosion sets in and leads to broken springs – the number one failure mode for spring brakes. Thanks to its innovative design, EnduraSure offers unmatched durability. In fact, in corrosion testing, EnduraSure even outperformed some “premium” spring brakes offered in the marketplace. Furthermore, recent design improvements to the power spring, service diaphragm and diaphragm retention make an already proven product even more robust to provide longer service life and help lower your total cost of ownership (TCO). EnduraSure ™ Spring Brake Threaded Park Side Push Rod for an improved internal seal No Touch ™ Power Spring plus epoxy coating prevents coil clash Diaphragm Retention redesigned for an improved seal Recent design improvements make a proven product even more robust.

Since the Life Seal chamber is completely sealed, contaminants cannot reach the power spring. The spring housing does not contain vent holes, external breather tubes, cage tool plugs or filters so the spring is isolated from the external environment. A special internal valve allows air to escape through the vehicles’ air system instead of through the housing. Life Seal Maximizes Output Force Most new spring rakes meet a minimum required output force. The ability for that spring to maintain output force is lost over time. Through technological innovation, Life Seal is the only actuator to maximize output force over an extended period. A unique patented power spring maintains high output force while increasing strength. The center tube guides the form-fit pressure plate, which stabilizes the spring coil through the full range of travel. This prevents contact with the spring housing and dramatically reduces coil clash.
