If I lightly press on the brakes, the pedal goes to the floor. If I press firmly or quickly, the pedal feels good and solid but will release and go to the floor eventually. So far, I've bled the master cylinder, the ABS, and the TCS. The same problem occurs. Any ideas?

very likely theres a leak internally in the master cylinder.

try with the vehicle off pressure the pedal fast and hard and build up pressure, put a even amount on the pedal, does the pedal slowly go down?
