So when taking my rear axles out I pulled one of the brake calipers off and disconnected the line... When input everything back together I had 0 brake pressure I've bled all the way around and it has improved but still doesn't feel right. Where should I start next?

 

You should bleed the Furthest caliper from the master and work your way towards the closest.
This may take multiple Bleeding on one caliper,,then again on the next,,and so on
What has happened is you let all the fluid drain,creating a void,( no fluid..air) so it is gonna take more than just re-bleeding that one caliper to get it back to normal.
Worst case scenario is "benchbleed" the master,and try Gravity feeding the calipers.(buckets under the calipers and letting the fluid Run Free once it has been established that fluid is coming to the Caliper.
This may involve more than one bottle of fluid,BUT the good thing is this may also Flush out any old fluid,so in a sense it is a smart thing to do.
By the way,the next time you go to Pull the Rear CV axle out,you can just pull the caliper off at the Bracket bolts(14mm).That leaves the whole Brake assembly together,and you can tie it up to the Shock spring to get it out of the way.I did that when I dropped the subframe to change the Diff..(Today as a matter of fact).
But then again,you shouldn't have had to take the Brakes off to change the axles.The Axle nut is accessable.It uses a 32 mm socket to remove the nut.
