Bleeding brakes

[Goinlow64]

I installed disc brakes on front and read and went to bleed the brakes and ran into a couple of issues. When I ran a vacuum on the rear passenger brake I could not get fluid to come out. I pumped the pedal a good 30 pumps and then still no luck.

I popped the top off and found fluid level had gone down in the front reservor, but not the rear. So, my question is...do I need to do something special to the prop valve to get fluid to the rear? My front flex lines are also leaking a tad, but I didn't feel like breaking that down tonight. I am hopeful it is just a loose connection, but feel free to let me know if you think it oculd be somethin else!

Thanks!
