Why do semi-trucks use drum brakes?

I was watching that "How is it Made?" on the Discovery Channel, and they were showing the assembly of a semi trailer, and they were putting on drum brakes.

for their application, the drum are used simply because due to the size of the trucks, they use air brakes in conjunction with the hydraulic. they are easier to maintain, and last longer.
