So a 1971 Chevelle. Sitting for 10 years. Put a good used master cylinder on and blew out lines and found the rubber line clogged. Changed the line and have fluid all the way back to the wheel cylinders. When we tried to power bleed by hold your foot on pedal and someone breaking the bleeders on the wheel cylinders the brake pedal doesn’t go to the floor or move at all. Fluid comes out of wheel cylinders but pedal doesn’t move. Have front brakes. Stumped and could use some help thanks.

Fill the master cylinder then top back on.Have the helper in the driver's seat make sure he listens to you.Open the bleeder then have the helper push the brake pedal all the way to the floor and hold it there. Repeat this at the wheel cylinders until you hear the air stop spitting out of the bleeders.
Make sure to keep the level in the MC up as the rear compartment is smaller than the one for the front brakes. I would check & fill the MC after every time you bleed the rear wheel cylinders.

Replace the wheel cylinders.

One thing you need to do if you use air to see if a line is clogged is to refill that line before you start bleeding the brakes again.

If you haven't already replaced the wheel cylinders that would be your next step. And don't let the rear MC compartment run dry either keep on checking and filling it.
