Another thought, I just finished putting mine back together, and the brakes suck again. I did not open the system at all. The only thing that changed was the EBC brake pads come with a vinyl pad that goes between the piston and the pad, they say it is to minimize vibration during break in. Well, those two pads came off, and now my brakes suck again. I am going to replace both front calipers and see if that helps. My suspicion is that the piston and/or seals have gone bad over the years. That little pad was enough to fill the gap and increase performance? I don't know, but that is all that changed on mine.
