There's no such thing as an air brake endorsement on any US license - only a restriction for CDL holders which bars them from operating a vehicle requiring a CDL which is equipped with air brakes if they don't pass the written air brakes test and perform their pretrip and road tests in a CMV which is equipped with air brakes.
No. Such an endorsement does not exist for US licenses.
