Oddly enough, I think I've seen this before. It was caused by someone "getting on" the brakes within about 500 miles of a change, before the pads were bedded...
Fix? Try taking the pads out, breaking the surface with sandpaper or emery cloth (80-120 grit should work) or a fine cut flat bastard file (double-cut if you have it, and only if you're sure of yourself! A file is rather more aggressive...) and reinstall. Hit the rotors with Scotch-Brite wheels if they seem glazed as well - it's a possibility.
Glazing on the pads or rotors will cause them to retain heat, meaning you'll get "brake fade" that much quicker. Wetting them down will help them cool, until the water evapourates - and you can direct a hose (rain doesn't usually get on things undercar, unless you drive through a puddle.)
TAKE IT EASY the first 500 miles or so - and the first time you drive it after doing a brake job, you'll want to do some long, slow, gruadual stops while "feathering" the brake pedal to heat up the pads - but not overheat them. I usually pick a carpark downstreet, and just orbit the thing a couple of times, not applying the brakes for more than about two seconds (and getting off of them 3-5 seconds.)
Do that for about ten minutes, and then slowly increase to a full stop from street speeds (but not a "panic" stop - smooth and even. If people honk at you, wave back.)
Granted, this isn't like "pre-bedding" on a brake dyno, but it helped with friction logevity with an old girlfriend I had - she drove an automatic with both feet, and I did brakes (four wheels' worth!) every eight or nine months...
If they're glazed, you can save them. If they're cracked, replace them - even if you break the glaze, they'll usually "chunk off" when you try to re-bed them, or at the first time you have to panic stop...
