Brake bleed
I just replaced my m/c, brake lines, and brake calipers, on my 69 corvette, I also bench bled the m/c but I can't get any brake fluid to flow from the m/c thorough the lines and into the calipers, pumping the brake pedal or gravity bleeding has not worked any help would be greatly appreciated.

I've had the best luck bleeding my brakes using a Motive power bleeder, based off recommendations from this site. Don't know if this would solve your problem or not, but I'd definitely look into it. My brakes never worked better than after I bled my brakes with the Motive bleeder.

1. Bleed the master Cylinder (Bench Bleed)
2. Bleed the master Cylinder (On car with rear raised)
Follow this.

3. Then I start bleeding the caliper lines. It doesn't matter the order you bleed if you don't care how much fluid is required.
I use this order to use the least amount of fluid.
1. Right Rear inner bleed screw then outer.
2. Left Rear inner then outer.
3. Right front inner then outer.
4. Left front inner then outer.
Here is how I bleed the lines.
I apply about 20PSI at the master cylinder.
I have 1 port for the front circuit and one for the rear.
If using a wildwood MC, you need to block off the unused circuit since the wildwood MC has a pass-through hole in the MC.
The only thing to need to check with this process is you don't empty the MC.
What I have done to help this is a cut the bleeder hose to about 4ft. Then I determined how many times I could bleed the hose without the MC going empty.
Once all bleeds clear I bleed / check the MC on the car again.
Remember to release the pressure of the air line before removing the line or you WILL / MAY Shoot brake fluid everywhere. Connect with no pressure and release with no pressure.

Pressure bleeding applies outward pressure so if there is a poor seal at the bleeder screw or the hose connection fluid leaks out vs air being added to the bleeder hose making you think their is air in the system.
