My biggest complaint with my stock brakes was in a panic stop. Once I went to new larger wheels with a performance tire, the front brakes wouldn't lock up no matter how hard I stomped the pedal. And, that was on the first try with the brakes still cool. Plus, the pedal always had a mushy feel to it in anything more than a normal easy type stop. I tried a several different pads, a couple of different stock type calipers, 3 sets of rotors, a few different master cylinders and couldn't make them feel any better. I finally gave up with stock front brakes and went with '98 to '02 Camaro LS1 brakes. it's great now.
