Chevrolet: brakes, chevy berretta, rear hub

Question
I have a 1994 chevy berretta 3100 v6, I have changed the rear hub assy.,and put new brakes on the rear I have put new brakes and rotors om the front,now when I bleed the brakes they pump up well until you start the car then the pedal goes to the floor, I have even tried bleeding them with the car running but that does not help . Can you help. Thanks Jeff

Answer
Hi Jeff;
       Ok  when you bleed it start from the r/r than l/r -than r/front and l/f  .and you might have to do it a few times to get all of the air out. and you must keep fluid in the master cyld. all the time - if it runs out you will have to start over again. after you do  all 4 wheels than with it running bleed the master cyld. also - if no bleeder on it just crack a line if 2 lines -- do the back one first remember keep the fulid full. it should be ok after that.
If you have a lot of air in the system you will have to get it all out.
