brakes

[Rlingren]

I have a 1974 spider. I put in a new brake master cylinder and primed it. I can get fluid out of front calipers to bleed them. There is no fluid going to rear calipers. Did I only prime one half of the master cylinder? Rear calipers are off and no fluid goes to the line in the rear at all. What do I check or do next?

Thank you

Make sure if the car is raised that it is raised by the axle or the compensator will not allow fluid to the rear calipers.
