Hi FWillson, I came across this post as I'm having the same problem on my 1976 Corvette. New back calipers and pads but can't seem to bleed the system to a hard pedal. The difference between our cars is mine has power brakes. I have a hard pedal when the car is not running. As soon as I crank the car, the pedal goes to the floor and won't pump up. I've run 2 quarts of brake fluid through the back 2 new calipers the old fashioned way with someone pumping and holding the pedal for me. I then purchased a Motive power bleeder and tried that. Nothing has worked so I'm wondering if the master cylinder somehow got screwed up when I replaced the calipers. Did you ever find a solution to your problem? I've bled the brakes on many many cars and have never had this problem and it's driving me crazy! Thanks Jay
