Just curious, what is the 'best' and most popular design for road brakes? I have generic dual pivot brakes on mine, and was amazed by how much they suck LOL (coming from disk brakes on my MTB, most any rim brake will seem bad I guess).

Also, whats more important for stopping power, the brake design/quality of brake, or the actual brake pad your running instead.

Enjoy.

There is only going to be a small difference in acutual stopping power from the brake construction of newer brakes. The major power differences are going to be in the pads and pad construction. (if you have old style brakes, forget all of this and get new brakes)

The better brakes have better modulation and will work with more smoothness and accuracy. This accuracy will be most evident when flying down a hill at 65 mph. And don't forget the weight differences.

At a nice balance between $ and performance look at the ultegra brakes, but replace the pads with dura ace or kool stop pads.

I have noticed brakes with a cartridge style pad have more power because there is less rubber to compress which directly translates to braking.

You want the best get some record brakes...lightest, stiffest and ball bearings not bushings.
Modulation/feel much more important than power.Spunout

So much so, that Campy uses single pivots on the rear, to further reduce available power. Not needed, you see.
good call, see pictsievers11

I can think of several twisty steep descents where I'd prefer a lot more power.

There are a few descents that are truely steep enough where a more powerful brake might be desirable -- but for the most part, the dual-caliper design is pretty effective. The limiting factor with road brakes tends to be the friction between the road and the contact patch of the tire, a very powerful brake will just make skidding more likely.

That said, the Dura-Ace 7410 dual pivot is probably the best brake ever made, in terms of balancing weight and power.
