It can take up to 3 qts to bleed brakes on an abs system was the master bled prior to installation? If not that is your problem you'll need to bleed again preferably with a power bleeder or vacuum. Here is a test to do on abs unit.
Probably abs hydraulic unit. If it is 2wal you should find a rubber cap on one end of the release valve. Take the cap off and stick a straightened paper clip in the hole. Have someone push on the brakes, if it pushes your paper clip then the 2wal valve is bad. Good luck
