Only in cases where the vehicle fits the criteria where it requires a Class C CDL. Examples would include vehicles designed to carry more than 15 passengers (including the driver), and vehicles carrying hazardous materials in a quantity sufficient to require placards to be displayed.
If a vehicle under 26,000 lbs. does not meet the criteria where it requires a CDL, then it can be driven on a regular Class C licence, whether it has air or hydraulic brakes, without any additional testing.
Air brakes have absolutely ZERO determination in whether or not a vehicle requires a CDL.

3000 pounds
Apart from the fact that a vehicle of that mass should not be on the pavement in the first place and that fact that pounds is a measure opf mass - not weight - the answer will depend on the pavement surface, quality of the brakes on the vehicle, the depth of water (aquaplaning/skidding risk).
Brakes are typically required on a trailer when it exceeds a certain weight threshold, which varies by jurisdiction but is often around 1,500 to 3,000 pounds. Additionally, if the trailer is designed to carry a specific weight, such as over 3,000 pounds in many states, brakes must be included regardless of the weight of the towing vehicle. It's important to check local laws and regulations to ensure compliance with specific braking requirements for trailers.
The towing capacity of the 1993 Mitsubishi Pajero depends on if the trailer is equipped with brakes. Without brakes, the towing capacity is around 1,650 pounds. With brakes, it ranges from 4,000 to 5,500 pounds
There is no actual air brake endorsement - if you test for a Commercial Drivers Licence (CDL) and either fail the written portion, don't road test in a vehicle equipped with air brakes, or both, you get an L restriction, prohibiting you from operating a commercial vehicle with air brakes. The only times you need a CDL for a vehicle or combination under 26,000 lbs. GVWR is if it's either carrying hazardous materials in a quantity sufficient to require placarding, or designed to carry more than 15 persons (including the driver). In the case of the former, you would need at least a Class C CDL with Hazardous Materials endorsement, and air brakes (if the vehicle is so equipped), as well as the K endorsement for a tanker, if the vehicle is so equipped. For the latter, you would need a P endorsement for passengers (S for school bus), as well as air brakes, if the vehicle was so equipped. If the vehicle you're operating doesn't fall into the criteria of requiring a CDL class licence to operate it, you don't need to be tested for air brakes.
