Air Drum Air Disc Air Brake S l a c k Hydraulics Brakes Brakes Chambers Adjusters A major breakthrough in safety, performance, and productivity

Bendix ® brand air disc brakes from Bendix Spicer Foundation Brake LLC offer safety, performance, and productivity – plus driver peace of mind – even under the toughest braking conditions. And the enhanced design means straighter, smoother stops.

Bendix ® air disc brakes offer safety, performance, and productivity – plus driver peace of mind – even under the toughest braking conditions. And the enhanced design means straighter, smoother stops.

With Bendix ® air disc brakes, the same size brake can be used on all axles. Traditional brake designs require different components on the steer, drive, and trailer axles, increasing the number of different parts required to service the brake. Bendix ® air disc brakes mean there are fewer parts to buy, fewer services needed, fewer parts to stock, and fewer brake inventory management costs.

The Bendix Air Disc Advantage Exceeds all Federally Mandated requirements for Reduced Stopping Distance Shorter Stops Signifi cantly shorter stops in demanding applications than even the best drum brake designs Passenger car like feel Better Braking Feel Superior Improved side to side brake consistency Performance Safety Greater braking power can result in fewer accidents Mono-block More compact than two-piece caliper models.

1. Pneumatic brake chamber forces the pushrod against the lever with force F1 . 2. Eccentric lever multiplies force F1 and applies force F2 to beam. 3. Beam transmits force F2 to a pair of threaded tubes and tappets. 4. Dual tappets spread force F2 evenly across surface of inner brake pad. 5. Sliding caliper distributes forces F2 and F2 1 equally between inboard and outboard brake friction pad. 6. Special brake pads, made of a carefully selected blend of materials for high stopping power and long life, apply forces F2 and F2 1 to rotor. 7. Heavy duty ventilated rotor is specifi cally designed to minimize heat distortion and optimize thermal stress endurance. As pads grip rotor, vehicle decelerates. 8. These wear sensors provide a continuous voltage signal that indicates pad and rotor condition.
