There is no such thing as an air brake endorsement on ANY license in ANY US state or territory. For people with a CDL, if they do not complete and pass the written air brakes test and perform their road test in a vehicle so equipped, they get a RESTRICTION on their CDL which prohibits them from operating a commercial motor vehicle which is equipped with air brakes.

No, because there is no such thing as an air brake endorsement on a US license.
There is no air brake endorsement. If a CDL driver does not complete and pass the written Air Brakes test and perform their road test in an air brake equipped vehicle, they receive a restriction which prohibits them from operating a commercial vehicle with air brakes.
You can't get one, because such an endorsement does not exist.
No. Such an endorsement does not exist for US licenses.

Depends on where you're at. In the US, there is no such thing as an air brake endorsement - only a restriction for CDL drivers who don't both pass the written air brakes test and perform their road test in a vehicle so equipped. In other countries, there is such an endorsement.
Only if it's either designed to transport more than 15 persons (including the driver), or else carrying a quantity of hazardous materials which requires the display of placards under the FMCSR. In both instances, you would need at least a Class C CDL without an air brake restriction (there is no actual air brake endorsement), as well as a passenger endorsement (for a passenger bus) or hazardous materials endorsement.
In some countries, to be permitted to operate an air brake equipped vehicle, your licence must show an endorsement which permits you to. In the US, "air brake endorsement" is actually a misnomer - there is no air brake endorsement on a US licence. If a CDL driver does not pass the written air brakes test and conduct their road test in an air brake equipped vehicle, they get a restriction prohibiting them from operating an air brake equipped commercial vehicles. However, this is only applicable to commercial vehicles - operating a non-commercial vehicle with air brakes requires absolutely no qualification, whatsoever.
You can't get an air brake endorsement ANYWHERE in the US on ANY class of license, because it doesn't exist.
Air brake endorsements fall under Federal laws so every state will have the same minimum requirement for an air brake endorsement if you have air brakes on your vehicle.
There isn't an air brake endorsement. If you haven't completed and passed the written air brakes test at the DMV and conducted your road test in an air brake equipped CMV, then you have a restriction prohibiting you from operating a CMV equipped with air brakes. You take the written test and do the road test in an air brake equipped vehicle.
