With a full load do you think you can lock the front drum brakes while driving down the road?
If so then no, the disc can't apply any more sopping power than that.
However, I think you will have a difficult time getting the front drum brakes to lock if you have lots of traction.
The disc will allow you to more easily and safely come to a stop with the same load, and will likely lock if you ask them to even with a full load.
I still think disc brakes have the potential for more stress on the system.
