You need a Class C CDL--you can't put that kind of endorsement on a regular drivers license. These days there's no such thing as an air brake endorsement; there is a "no air brakes" limitation if you come to your road test in a truck that doesn't have them.
No such thing as an air brake endorsement on a US license, period. If a CDL driver does not pass both the written air brake test and perform their pretrip and road test in a vehicle so equipped, they receive a restriction which prohibits them from driving a vehicle so equipped - if that vehicle requires a CDL to begin with. The restriction does not apply to vehicles which do not require a CDL.The only instances in which a vehicle of 26,000 lbs. GVWR or less requires a CDL is if it is a: hauling a quantity of hazardous materials which requires placards to be displayed per 49 CFR or b: a bus designed to transport more than 15 persons (including the driver). Otherwise, a CDL is not required, and air brakes have absolutely no bearing on that.
Air brakes have absolutely ZERO determination in whether or not a vehicle requires a CDL.
No. Air brakes are not a parameter in determining whether or not a vehicle needs a CDL.
Only if it's a vehicle equipped with air brakes.
No
In the US, no - there is no such thing as an air brake endorsement - only a restriction for CDL holders who don't pass the written air brakes test and complete the pretrip and road tests in a vehicle equipped with air brakes, which prohibits them from operating vehicles requiring a CDL which are equipped with air brakes.
The air brakes don't matter, insofar as whether or not a CDL is required. As for the GVW being over 26,000 lbs., yes, unless your vehicle falls in criteria for the farm vehicle, military vehicle, emergency vehicle, or recreational vehicle exemptions.
No. The gross weight cannot exceed the gross vehicle weight rating and/or the registered weight rating of the vehicle, regardless of the license of the person driving it.
If it's not a firefighting or first response vehicle, recreational vehicle, registered farm vehicle, or military vehicle (operated by military personnel in the course of their duties), then yes - not because of the the air brakes, but because of the weight rating of more than 26,000 lbs. GVWR.
Only if it's hauling hazmat or is a bus designed to transport more than 15 passengers (including the driver). Air brakes have absolutely nothing to do with whether or not a vehicle requires a CDL.
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.
Air brakes are entirely irrelevant as far as whether or not that vehicle needs a CDL is concerned. The only time you need a CDL to drive an RV is when you're operating it on a for-hire basis, either as a driver for hire or as a transporter.
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.
