L/R caliper won't bleed???

[MrFairlady]

I can't seem to get the L/R caliper to bleed.Only a small amount of fluid comes lout but pretty much Stays in the Clear tube.
R/R Bled fine (haven't made it to the fronts yet).

I tried to Bench bleed the Master before installing but didn't get it done as good as I would imagine it would have.

Replaced the L/R caliper w/ a diff one and the same Issue.
I've been using Speed Bleeders and even tried using the Regular Bleeder Valve.No DIff.
PEDAL does not seem to really build pressure.Dosen't get THAT hard after multiple Pumps.You can hear the Master pumping though.

WTF could it be???

Air in the master.... Rebleed it.... You gotta get all the air out of the master period. No bubbles...

so even if the R/R caliper bled Fine?

Damn I do not wanna pull the MC again.Engine bay is Uber Clean and I wondering if I grab the Vac Puller from work and suck the fluid through if that would work.
