We're glad to share this kind of info. All thanks to Jefferson County. Since our video service is relatively new, what kinds of videos would you like to see in the future?

Would you have videos that cover retarders? (it's not a joke). All I know is that they help prevent wear and tear on brake pads by slowing down the engine.

[STNMagazine]

will look into this and see if we have a video for you. thanks for watching.

I notice sometimes when a commercial vehicle is parked you can hear the sound of air releasing from the vehicle. Now days I learned that is from the air brakes. What is happening when the air brakes make a releasing sound when the vehicle is parked?

Thanks, just what I was looking for! You will part of my success when I pass my air brakes test for school bus.

Whoa! Still making this system.. I thought the electronically controlled brakes have replaced this ancient system everywhere which is just a back-up system of the ECB.

The system has significant advantages over this old-school system the more axles a vehicle has, such as the brake blending (jakebrake+retarder+service brakes together), ABS works faster, The ESP wouldn't be even possible without it, no lag between the front- and rearmost axles, equal wearing with disc- or drum systems etc.
