First road bike: braking?

I'm in the market for my first road bike. I currently use a '94 Trek
970 mountain bike with slicks for commuting (3 miles) that I've
upgraded several times over the years (notably XT V brakes, Rockshox
FSX carbon fork, and a few other things) but I've been doing some
slightly longer rides and have found it uncomfortable, particularly my
hands get numb after a while.

So, I've been test driving a few road bikes. While they have all
seemed to be more comfortable and seem more efficient, the brakes have
invariably seemed to be far less powerful than I'm used to. Is this
universal for road bikes? Is there any way to make them stop faster?
