Depending on what the truck is, it may have air brakes, air-over-hydraulic brakes, or hydraulic brakes. Air brakes may be foundation brakes, to include flat cams (very rarely seen), S-cams (the most common), or wedge brakes (not so common anymore, although they are sometimes used on the steer axles of heavy haulers and vocational trucks), or they might be disc brakes, or now, even piston brakes (as far as I know, UPS is the only major carrier which uses them). Depending on country, truck brakes will either use ABS (in N. America) or EBS (in Europe).
The brakes will remain on, air pressure is required to release the brakes
Most certainly for without friction the braking system would fail no matter how much force was applied.
Braking
Antiliock braking system is the mechanism which controlls the braking of brakes, If the pedals are fully pressed it will oppose the motion to protect your braking
A hybrid truck will run on electricity generated by the braking system. It will also run on gasoline when needed, just like a regular truck. Hence better gas mileage.
The braking system doesn't determine whether or not a vehicle requires a CDL.

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.
On the 4WD SR5 truck, front brakes are disc, and rear brakes are drum.
ABS means Anti-Lock Braking System!
This could be short for a vacuum leak in, say, a vehicle's fuel/air mixture inlet system or in the braking system of a train or a truck that uses vacuum-operated brakes.
