Almost done with it but having trouble with the back brakes! Rebuilt master cylinder but still just pushes air with a little brake fluid. Thoughts?

You could take the caliper off. put it so the bleeder is at the highest point. make sure to put something in between the pads to take the place of the rotor. bleed away, make sure you don't run the res empty or you will just be getting more air in the line. if you have a mighty vac handy it will save some time with the pumping.

Also, how 'bout an little intro? location, 2t and cr5 experience.
