Sounds to me like you are air bound. did you bench bleed the master cylinder? And bleed the brakes, starting at rr, then lr then rf then lf

My brother's '91 Camero had the same deal. He swapped out the rubber line between the caliper and the steel line and it was all good. Something about the rubber breaking down in the line.

I know I never run the stock rubber lines on the old race car.

I had a 85 IROC Z28. The front locked up. I replaced the rubber lines between the calipers and the frame. Problem solved. remove the line at the caliper, have someone press the break peddle. see if any fluid comes out of the line. Then replace the line, when it doesnt.
