i took the whole rear suspension off a 93 del sol(had good rotors and pads

and put it on the crx dx. used the del sol master cylinder and proportional valve(or however u say it) and bled all four brakes with the aircompressor bleeder. No lines are leaking as far as i can see. The pedal feels good, fairly hard, and the pedal does not creep down at all, ever, but the cars braking is worse than when it had drums on the back. I cannot come to a complete stop without pumping the brakes atleast twice. What am i doing wrong? Can anyone give me suggestions on how to fix this?
