I just replaced my front disc's , bearings , and calipers on my 77 911. I also replace the break hoses. The calipers were rebuilt by PMB.
I filled the master with fluid but I am not getting fluid to my calipers with the bleed screws open. I let them sit for 1 hr but still nothing.
What do I need to do?

Thanks for the help

While you were waiting for the caliper rebuild, what did you do with the master cylinder? If you let it drain empty, you'll probably have to bleed it. Usually you bench bleed a new MC by filling with fluid, then working the shaft in and out with the MC in a vise, and short hoses on the outlets to recycle the fluid back into the reservoir. You'll probably need to rig something up and get a helper so you can bleed it with the brake pedal. Otherwise the body is full of air and probably won't let any fluid to gravity flow to the calipers.

I would also manually fill the calipers with fluid while tapping them with a mallet to get out as much air as possible, and only then connect up the brake line.
