Spring Brake.

The Bendix

is unsurpassed in performance, durability, and safety. This new Double Diaphragm Spring Brake leverages 80 years of proven Bendix engineering with next generation design and materials to deliver a premier spring brake for commercial vehicle ﬂ eets looking to optimize their operating dollars.

The Bendix

• utilizes a ground-breaking design that increases the height between coils on the

compressed power spring by 33% over typical designs. Increased spacing helps avoid damaging contact of the protective coating which leads to corrosion and, ultimately, fractures;

• incorporates service and parking diaphragms designed with optimized geometry

and heavy duty materials capable of providing more braking force when you need it most;

• features an advanced “Slotted Center Seal” design to improve the alignment of the

moving parts, reducing wear and extending life;

• weighs in at up to 8 pounds per tandem axle lighter than most comparable

designs; and

• meets all SAE standards for output force, meaning your vehicle will park with the

same assurance each and every stop.

Durability

The power spring housing in the Bendix® EverSure® spring brake has a larger shut height. This increased area dramatically reduces coil contact in the compressed power spring and increases the number of active coils, reducing stresses and increasing the durability of the power spring. Our exclusive, smart design helps reduce costly repairs and improves operating costs.

Safety

The Bendix stroke offering you more force when you need it most – during high braking duty cycle conditions. Corrosion resistant epoxy coating, and advanced designs which reduce the stress on the power spring, extend the spring brake’s life nearly three times that of competitive products on the market today. Power spring force outputs are maximized, enabling safe parking in all conditions.

The Lighter Weight With No Compromises

A new, patent-pending rear housing design reduces weight by up to eight pounds per tandem axle compared to the leading competitors. Our precision engineered enhancements – spanning the full range of the Bendix EverSure spring brake – delivers weight optimized performance along with reinforcement to key areas of the housing – so that strength, durability, and performance are never compromised.

Performance

Our pioneering design and mechanical enhancements provide:

• Additional braking reserve at all pressures

• Improved braking efﬁ ciency, offering as much as 190 pounds of additional output force when compared to the leading competitive OEM spring brake in extreme conditions; and

• Consistent and reliable parking force output.
