On good road conditions the front brake should be the one seeing more use, so maybe there's room for some technique improvement.
If you are going for a new front wheel there's an excellent chance to switch brake solution as well. S-A has a drum brake/dynohub combo. Shimano has a roller brake/dynohub combo. I'm not currently aware of any disc brake/dynohub combo, but I can't say that I've looked for one.
IMO there's a small advantage to drums when compared to discs for a commuter. Although discs these days don't require a lot of care, drums are an even more fit & forget type of thing.
