Apply the brakes. Do not 'pump' the brakes ... that's what your dad learned, in the 70's. ABS means that the brakes will automatically apply and release in micro-second bursts (faster than you could ever do it) to prevent the brakes from locking up and to prevent the tires from skidding.
All you do is hold the brake pedal down, steer in the direction you are heading in case you start to skid, and then smoothly accelerate.
If your brakes go out while driving, first shift the vehicle into neutral and then apply the emergency brake. If neither of these slows the vehicle, turn on your safety lights and get into the right lane.
The answer can be yes or no here, situation dependent. If you intend to operate a CMV equipped with air brakes, the answer is yes - if one does not pass the written air brakes test and perform their road test in an air brake equipped vehicle, they get a restriction on their license prohibiting them from operating commercial vehicles equipped with air brakes.
There is no air brake endorsement. A CDL driver who does not complete and pass the written air brakes test AND complete and pass the road test in a vehicle equipped with air brakes gets a restriction prohibiting them from operating a commercial vehicle equipped with air brakes.
Be pointless. The point of anti-lock brakes it to effectively "pump" the brakes for you.
The driver would need to step on the brake pedal when braking a vehicle equipped with anti-lock brakes. FYI, the driver would also need to step on the brake pedal when braking a vehicle that is NOT equipped with anti-lock brakes. Hope this helps.
For driving an air brake equipped vehicle, or for working on them? To work on them, you have to get the ASE certification. You must take and complete that ASE test to become certified. To drive a vehicle equipped with them, assuming you're in the US, there is no such license. If you have a CDL, then you must complete and pass the written test and do your road test in an air brake equipped vehicle, or else you get a restriction which prohibits you from operating a commercial vehicle equipped with air brakes.

If the vehicle is for commercial/business use, or otherwise does not fall into an exempted category with the FMCSR which makes it not require a CDL (and is operated within the conditions which must be met for that exemption to be applicable), then that vehicle requires a CDL. If it is equipped with air brakes, and requires a CDL, then the driver must have completed and passed the written air brakes test, and must have performed their pretrip and road tests in a CDL vehicle equipped with air brakes. Otherwise, they get a restriction which bars them from operating a vehicle which requires a CDL and is equipped with air brakes. If the vehicle does not require a CDL, then no endorsement for air brakes is needed - air brake endorsements do not exist on US licenses; only the aforementioned restriction for CDL holders.
Good luck trying to get such an endorsement, because such a thing does not exist on US licenses.The answer is no. Someone who holds a CDL must complete and pass the written air brakes test and perform their road test in a vehicle so equipped, otherwise they get a "no air brakes" restriction which prohibits them from operating a commercial vehicle equipped with air brakes, but doesn't prevent them from operating a vehicle exempt from CDL requirements which is equipped with air brakes.
On a US licence, there is no air brake endorsement - there is only a restriction for CDL drivers from operating a commercial vehicle equipped with air brakes if they don't complete the written test AND road test in a vehicle equipped with air brakes.
As with non-emergency vehicles, you typically only see them on vehicles with a GVWR of more than 26,000 lbs.
There is no air brake endorsement. If you do not pass the written air brakes test AND complete your road test in a vehicle equipped with air brakes, then you get a restriction which prohibits you from operating an commercial vehicle which is equipped with air brakes. It is possible to have a Class A CDL with an air brake restriction.
