Chevy II Front Brake Conversion problem

Helped change buddies Chevy II front drum to disc brakes. Have bled system and cannot get any pedal, we checked master cylinder, measured plunger to see if correct, all okay. After checking master cylinder, still cannot get pedal, so we unhooked brake lines and plugged master cyl and got a good pedal. Then we plugged proportioner valve and had good pedal there. Hooked back brake line up and bled lines, finally got good pedal on back brakes. Then we unhooked back brakes and hooked up front...still cannot get good pedal on front. The way the front brake line is hooked to proportioning valve, should we run dedicated line from proportioning valve to each front wheel? Does anyone think this will help or are we doing something wrong all together? I have heard power bleeding might help but I don't understand how this will help if we are getting good fluid out of all lines (front and back) Some one please help....frustrated.

Trevor

The first thing to check is if you really have bled the calipers. Try taking the caliper off and the bleed it so you know that the bleeder is at the top and you get all the air out. any air will make it very soft pedaled. Keep working back to the master cylinder and you should find whats wrong. Good luck

Did you put the calipers on the correct side, the bleeders must be at the top. I have seen this many times where the wrong caliper is installed on the wrong side. If the bleeder is at the bottom you need to swap them arround.
