It's good that you've changed disks/pads, that should give a good base to work from.
Under what conditions do the brakes work better or worse, after repeated stops, etc?
If you pump the pedal then does the brake pedal feel harder and the car brake better?
If so, then it's very likely that your fluid is past it's best.
What is the colour of the brake fluid in the reservoir?
