brake bleeding

About to pull my hair out. Have been bleeding sidecar brake for two weeks now. Have run 4 bottles of fluid through. Have used suction, speed bleeders etc. Clear fluid with no bubbles comming through. No pedal. Disconnet at quick disconnet pedal is firm. Hook up- no pedal. New brake lines, new pads etc. Brake does work but pedal easily pushes alway through to stop. My other Hannigan was no problem but this one.............@#!!!!! Just looking for some good Karma before I pull out the hammer. :o:-(
