The question everyone is trying to ask is "did you open up the system" and by that did you remove the calipers from the car, did you crack open brake lines or any part of the system that exposes the brake fluid.
We know you lifted the caliper off the rotor to replace the rotors but you don't have to crack open the system for that.
If you did open up the system, then you have not completely bled the air out of the system. If you did not crack open the system then something else is going on. Its almost always an air in the line problem once you crack open a line or remove a caliper from the car (not just its mounting location).
So is the pedal soft, or do the pads just not grab?
Soft pedal, then re-bleed.
I replaced the stock pads on my C5 with Hawk HPS, and did the bedding procedure. When I first hit the brakes, before bedding, I almost went right through a red light...
They got much better after bedding, but still not as good as the stock pads when cold. They have now been on for a couple thousand miles, and seem to be improving, but still need some heat in them to have the same feel as the stock pads. With a lot of heat they are much better.
