I installed them 1.5 weeks ago and am driving my car. I noticed a spongy brake pedal and poor braking performance, as well as a lot of brake dust coming out of my DS's front wheel. I picked up the car this weekend and was told that the outer driver's side brake pad is about 50% warned! Maybe after 200 miles of driving! It must have been a broken pad as the other three pads look fine. I also have a power stop brake kit for my rear brakes and they are working well with about 500 miles so far. All rotors are in great shape but I can't trust the pads.
