Stopping a vehicle with good brakes from 20 miles per hour under good conditions requires about 80 feet. Leaving at least 80 feet will allow you to stop safely without hitting the car in front of you.

The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.
try stopping a car without brakes!
stopping distance is the distance it takes for a vehicle to come to a full stop from the moment you apply the brakes
No, the purpose of anti-lock brakes is to prevent your vehicle from skidding in adverse conditions and during an emergency maneuver. The system will pump the brakes for you.
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 have absolutely ZERO determination in whether or not a vehicle requires a CDL.
most all newer vehicles have disc brakes, they are engineered for size and weight of the vehicle, they produce more stopping power than drum brakes
The presence or absence of air brakes has no impact on whether or not that vehicle requires a CDL.
It depends on the road conditions, as well the state of your brakes.
Depends on the vehicle and braking system. In a commercial vehicle, the brakes are designed specifically for stopping a loaded vehicle, and an unloaded truck can actually require more stopping distance than a loaded truck.
