1968 Mustang, I put new front calipers on after the car set for a few month, rear brakes bleed fine , but not getting any fluid out on front ones?

I'm lost on this one unless the master is bad???

Do you get a pedal?

1. Have someone pump the brakes up.
1.b Crack open the line at the master cylinder while holding the brakes. You should get fluid. If no fluid try a few times here till you get fluid.. If never fluid here, bad master cylinder. Also be sure your helper is pushing far enough.
2. Pump up brakes and crack line open at caliper. If no fluid, try more than a few times till you get fluid.
2.a if no fluid at front hose/line into caliper, and since you have disk breaks, check the proportioning value that balances brake pressure front to back. Could be bad. Might attempt to crack front lines line open at this value after pumping up brakes.
3 Rubber front brake lines could be bad? Both, seems unlikely. Sometime they go bad and block fluid flow. I have heard of the casing fluid to not return, making the caliper hang out. (I assume you tried to bleed both fronts?)
