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.
Not all disc brakes are the same.
Created from the power and expertise of global R&D and precision design, our air disc brakes offer a two-pin floating caliper design that balances wheel packaging and reliability. This unique two-pin design utilizes fewer components than four-pin air disc
brakes. The decreased number of components provides more stringent overall dimensional accuracy, consistent force distribution, and longer brake system life. Dual, internally adjusted pistons allow the Bendix® ADB22X™ air disc brake to offer the most precise brake adjustment, better force distribution, and more even pad wear than any single piston caliper design. In addition, the Bendix®> ADB22X™ brake is the lightest dual piston design available.
Other key benefits:
-
Internal automatic brake adjustment allows the brakes to always be in a state of optimum adjustment.
-
Virtually no brake fade and no degradation in stopping power.
-
Straight, stable stops due to minimized brake force variation between brakes.
-
Optional integrated pad- and rotor-wear sensing optimizes pad and rotor life and minimizes the number of required maintenance checks.
-
Optimized friction pairing results in minimal fade and maximized pad and rotor life.
-
Global reach and expertise. Bendix Spicer Foundation Brake, Bendix, and its German affiliate, Knorr-Bremse, have more than 10 million air disc brakes in service worldwide and produce nearly 2 million air disc brakes annually.
Superior performance on long downhill grades.
There are two types of brake fade – mechanical and friction. In an air disc brake, as heat builds up, the rotor expands toward the pads, thus significantly removing mechanical fade from the equation.
With the Bendix® ADB22X™ air disc brake, brake fade is nearly eliminated by optimizing the friction couple.
At Bendix Spicer Foundation Brake, we developed the metallurgy in our 17-inch rotor and paired it with our advanced friction material specifically designed to optimize friction performance at high temperatures, thus significantly reducing brake fade and maximizing brake pad and rotor life. As a result, there is virtually no degradation in stopping power when brake temperatures rise under heavy use.
Compact design minimizes weight and maintenance.
Bendix air disc brakes feature a mono-block caliper design, which makes the brake more compact than two-piece caliper designs. The mono-block design also offers better sealing from the environment for better protection from the elements. Engineered to fit most truck wheel-end envelopes, Bendix air disc brakes offer commercial vehicle drivers top performance, durability, and long life.
Stopping power that is smooth, straight, and safe
Constant brake pedal effectiveness and passenger car-like feel.
Bendix air disc brakes are preferred by virtually all drivers who have experienced their performance, stability, and feel. This can aid in driver retention and recruiting, and also extends added value throughout the entire operation for a fleet that runs on Bendix® air disc brakes.
Greater stability during stops.
The result? The air disc brake equipped vehicle more easily comes to a straight, stable stop. The right to left side brake performance of other brake designs can vary up to three times as much, making steering corrections necessary to keep the vehicle on its intended path.
With consistent brake performance, a vehicle with Bendix air disc brakes at all wheel-ends also benefits from improved overall brake balance.
Shorter stopping distances.
What’s more, with air disc brakes, drivers gain immeasurable peace of mind knowing they will always have the braking force needed to stop safely or negotiate a grade.
Dramatically reduced downtime during service
Changing air disc brake pads takes less than half the time it typically takes to change drum linings, reducing downtime and labor costs.
Every component has been engineered to provide a longer service life. This means drivers spend less time waiting around for service – and more time driving, providing significant savings in maintenance, labor, and downtime.
Advanced engineering from the industry leader
Reduced part number complexity and component proliferation.
With Bendix® air disc brakes, the same size brake unit 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 fully service the brake system. Bendix air disc brakes mean there are fewer parts to buy, fewer parts to stock, and fewer brake inventory management costs.
