A full wheel-end portfolio from Bendix — featuring of the Bendix ADB22X air disc brake, Bendix EverSure spring brake, Bendix Versajust LS slack adjuster and Bendix foundation drum brakes — is now available on a range of International’s medium- and heavy-duty trucks.
Leading off the Bendix bundle lineup, customers can improve their stopping power by spec’ing Bendix ADB22X air disc brakes as an option on all Class 6-8 platforms where air disc brake technology is available; or by taking advantage of the proven performance of Bendix foundation drum brakes, an option on all Class 5-8 air-braked vehicle platforms. New as an option on International’s entire lineup of Class 5-8 air-braked tractor, truck and bus platforms is the Versajust slack adjuster, with the EverSure spring brake standard on the same vehicle set.
By making the component bundle available, International Trucks is enabling fleets and owner-operators to gain the significant benefits of a complete wheel-end package designed by a single provider for optimal performance.
“Navistar is making it possible for fleets and owner-operators to realize the value of a comprehensive wheel-end package engineered by a single provider. They know they’re getting Bendix components that have been designed, developed, validated, and certified together to optimize their performance,” said Scott Burkhart, Bendix vice president of sales, marketing, and business development.
The Bendix ADB22X air disc brake, which accounts for more than 90 percent of the North American Class 6-8 wheel-ends outfitted with air disc brakes, features a lightweight design that significantly reduces stopping distance and extends brake system life.
Air disc brakes offer the advantages of quicker pad replacement and longer brake lining life, leading to greater uptime and lower maintenance costs; car-like feel and straight, stable stops; and greater reliability due to virtually no brake fade or degradation of stopping power. Air disc brakes also include an internal self-adjustment mechanism that can help lower the risk of brakes being found out of adjustment during inspection, which can affect Compliance, Safety, Accountability (CSA) scoring.
Bendix foundation drum brakes are available in multiple North American Class 5-8 International models to meet a wide variety of applications. BSFB is the only brake manufacturer to offer both single and double anchor pin foundation drum brakes to the original equipment market. Single anchor pin brakes are available on trucks, tractors, and trailers, while double anchor pin brakes are available for trailers and vehicles serving specialty applications.
The brakes are engineered for improved stopping power and resistance to brake fade. Bendix ES (Extended Service) drum brakes feature bronze bushings, precision camshafts, lower fade lining formulations, and in some cases, structural reinforcements to manage higher braking loads. Bendix’s OE E-coat process offers improved corrosion protection to help prevent rust jacking.
In combination with wide-brake packages, Bendix ES brakes typically extend the brake life of highway tractor trailers by more than 60 percent, eliminating a significant number of brake relines and improving cost-per-mile.
The design of the Bendix EverSure No Touch power spring virtually eliminates coil clash, protecting the premium epoxy coating used on all Bendix power springs and improving corrosion resistance. This results in a longer-lasting product, fewer repairs, less downtime, and lower fleet operating costs.
EverSure is also engineered with a greater power spring shut height, reducing stresses on the spring and allowing it to better maintain its force output over time. Additionally, the brake’s weight — up to eight pounds less per tandem axle than most comparable designs — offers the potential for increased payload and improved fuel efficiency.
The Bendix Versajust LS slack adjuster with the WearMax clutch can extend lining life by up to 16 percent and brake drum life by up to 30 percent, while improving safety and compliance. Versajust introduced key enhancements to automatic slack adjuster technology with its WearMax clutch, which allows for a gradual, continuous, and more precise adjustment of the running clearance between the brake shoe and drum.
This tighter running clearance provides the maximum brake chamber reserve stroke while creating a quicker response time for brake application. At the same time, Versajust avoids the problem of dragging brakes, which can occur in slack adjusters that adjust prematurely as the drum heats and expands during normal braking. When the drum cools down, that running clearance is reduced — or even eliminated — which can result in a dragging brake, higher brake temperatures, and accelerated wear.
The Versajust slack adjuster also features patented bronze friction rings, increased corrosion resistance, and a stronger seal to provide durability across a range of environments and duty cycles. It is engineered for easy installation and maintenance without the need for special tools, attachments, templates, or brackets.
