Bendix touts new ‘No Touch’ technology spring brake

Updated Jan 19, 2011

Bendix Spicer Foundation Brake has announced a new, next-generation double-diaphragm spring brake for drum brakes. According to Bendix, the new EverSure spring brake offers the lightest weight in the industry while delivering best-in-class durability and performance. The EverSure spring brake is designed to industry-standard dimensions, making it easy to install as a replacement part in the aftermarket.

“In engineering the EverSure spring brake, we created a high-performing spring brake that is significantly lighter and, at the same time, more robust than others on the market,” says Mark Kromer, chief engineer – actuation/slack adjuster products, for Bendix Spicer Foundation Brake. “The new spring brake meets the strictest standards for performance and durability.”

Bendix says the EverSure spring brake is more than two pounds lighter than competitive spring brakes. For trucks and trailers outfitted with the EverSure spring brake, key benefits of the weight reduction include the ability to carry increased payload and improved fuel efficiency. The lighter weight design helps offset the extra weight added to commercial vehicles by engine systems designed to meet recent emissions regulations. The product’s lighter weight also leads to the best vibration resistance in the industry.

Another key advancement in the Bendix EverSure spring brake with NoTouch technology, according to Bendix, is the elimination of contact between compressed power spring coils, allowing the protective coating to remain intact and resulting in significantly better corrosion resistance than competitive products.

“We designed the power spring of the EverSure spring brake to avoid coil contact damage, which leads to corrosion, and ultimately spring brake failure,” Kromer notes. “Engineered with an increased number of active coils, the EverSure spring brake also reduces surface stresses in the power spring. The elimination of coil contact and the additional active coils allow the EverSure spring brake to set the benchmark for durability.”

Bendix says its engineers also optimized the diaphragm geometry of the EverSure spring brake, resulting in best-in-class force output. While it is also available in the aftermarket, the EverSure spring brake exceeds all compliance requirements for performance and durability in Original Equipment.

“We have performed extensive validation tests,” Kromer said. “Our corrosion tests, for example, demonstrate the improved durability of the EverSure power spring over competitive designs. The EverSure lasted more than twice as long as other Original Equipment power springs. Also, our testing requirements are far more stringent than the commonly accepted SAE standards.”
