I tryed another master cylinder. That didnt work. Could it be the abs block that is not allowing enough preassure? they have very little and they lock up. the abs and brake light are on in the dash.

Ok so the other day i took my 01 2500 apart to install new ball joints. I took the brake lines off the calipers to give myself more room to work and when i went to reinstall everything went smoothly. I bled the lines i have full pressure coming from all 4 calipers. I cannot get any foot pressure. I tryed a "new/used" Hydroboost and it was not the problem. I am out of ideas and cannot get the pedal to hold pressure. I start it and try to move it doesnt grab till the very bottom and not to much. ` :confused: I think there could be air trapped in the abs sensor? I have no idea any help would be great. Thanks in Advance!!!!!!!
