I like @
bulldog1935's suggestion, but putting new pads on the existing brakes first will get your bike on the road faster. New pads can create a dramatic improvement. If you still feel that the brakes are lacking after you ride it for a while (or just want to indulge some upgraditis), buy the cheap Weinmanns since they are better quality than what you have and super cheap. You can even transfer the new pads over to the Weinmanns.
Also! Post a full driveside pic of the bike! I haven't heard of this brand before. Pinarellos and Colnagos are obvious rehab candidates and pop up plenty often around here, but I love to see people showing these love. I think you can have just as much fun with something like this. Plus, I like the colors!
