Below is from another site online, in case helpful:

"It possible that could be air still in the system. In general if it's air you should be able to pump the pedal and have it come up and be firm and hold that level. Air compresses while the brake fluid does not. If you allowed the fluid level in the master cylinder to drop to the point it could draw air in you may have air trapped...

If you pump the pedal and it goes firm but slowly drops while you hold it you may have an additional leak somewhere or you could have a bad master cylinder. During normal use brake fluid can become contaminated and the master cylinder wears internally but only for the length of your brake pedal travel. If you used the pump the brakes method to bleed them your pedal travel is greater than normal (perhaps ever in the history of the car). This will push the internal seals over new territory which may have some internal rust, a wear ridge, etc... causing the seals to tear. Once this happens the break pedal will never hold firm again. Pumping the pedal may help but under pressure it will have a slow drop."

Fwiw...Brent
