brakes hardly work

swaped to sr. Removed abs actuator to put in harness, swapped master cylinder because old one was broken, Dot 4 brake fluid, bled the lines over and over, every single line so there is no air. When you pump the brakes when car is off brakes go firm. When car is on there is no pedal feel and the brakes barely work. Any suggestions to what it might be?

possibly booster or your new master, so long as ur brakes were ok before
