An FMVSS 121 compliant air brake system is supposed to be regulated to where the cutoff pressure is between 115 and 135 PSI and the cut-in pressure is no more than 20 psi below the cut-out pressure. The absolute minimum cut-in pressure for buses is 85 psi, and for trucks it's 100 psi.. otherwise, the air governor needs to be replaced.
60 psi is the hold off pressure for a spring brake system, while brake emergency chambers are governed at 90 psi.
Generally adjusted for 125 psi but they also have a blow-off valve that releases anything over 150 psi for safety purposes.

This is the maximum amount of weight a vehicle can tow, if what being towed has brakes. A towed vehicle with brakes (electronic brakes) responds to the same braking that the vehicle doing the towing has. If the vehicle being towed does not have brakes, the maximum towing capacity is much less.
Simply a question of Force distributed over a much smaller area in the case of disk brakes (or higher pressure)

How much pressure do you apply to the brakes? How should you change your driving in rain?

No one knows exactly how much pressure the human body can withstand, but it is deeper than 1,500 feet.
No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
Some trucks have much stickers. Others have not much sticker. I like stickers.
S-series brakes are notorious for being much different than any other cars brakes. They have alot more "Feel" to them and seem harder than other vehicles. This is normal. As long as they dont loose pressure they are fine
Assuming the front and rear brakes have been bled properly and if the vehicle has rear drum brakes, that the rear brakes are adjusted properly, with engine off and vacuum depleted from the booster, the pedal should drop aprox 1/4 of its total travel distance with firm but not extreme foot pressure.
The hold off pressure for the spring brakes if 60 psi, and brake chambers are regulated at 90 psi.
