How can you be sure that trailer brakes are not "supplemental" in function?

What is there to say that they have the power to stop 100% of the trailer weight?

I have researched it and cannot find any information on it.

Brakes on any vehicle are sized to the highest GAWR.
NHTSA says this about components of the GAWR:
"Gross Axle Weight Rating is the rated load-carrying capacity of an individual axle and wheel assembly. (It represents the load that may be steadily sustained by the components in the system; i.e., tires, rims, hubs, bearing, axles, brakes, suspension, sub frame, etc. with the GAWR limited by the components with the lowest working rating".

and

from AL/KO axles

(Gross Axle Weight Rating) is the maximum load that the axles will
carry and the maximum load the brakes will stop.

Thanks for the explanation. That means there must be brakes on both axles of the average tandem axle trailer.

I did always wonder about that part.
