While I believe air brakes should be an endorsement, for a non-CDL vehicle, there are no additional requirements imposed when the vehicle is equipped with air or air-over-hydraulic brakes.
The need for a CDL is determined by the Gross Vehicle Weight Rating. In your case, the vehicle is rated at 26,000 lbs., which doesn't require a CDL.
However, if it carries a quantity of hazardous materials which requires placards to be displayed, or if it were a bus designed to transport more than 15 persons (including the driver), then it would be a CDL vehicle at any weight, and air brakes would have an impact.
A driver who tests for a CDL must take both the written air brakes test and perform their road test in a vehicle which is equipped with air brakes. Otherwise, they will get a restriction which prohibits them from operating a CMV which is equipped with air brakes (however, this restriction does not apply to non-CDL vehicles).
No
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.
26000 increased by 30 percent =33800=26000 + (30% * 26000 )=26000 + (0.3 * 26000 )=26000 + 7800= 33800
To answer you we need to know what country's traffic regulations you are asking about.
26000
No, unless you're hauling something which requires a hazmat endorsement, such as contaminated soil.
7% of 26000 = 7% * 26000 = 0.07 * 26000 = 1820
70% of 26,000= 70% * 26000= 0.7 * 26000= 18,200
