Bad Master Cylinder or Air?

I have not. I don't always have an extra person around to help bleed the brakes, so I ordered a vacuum bleeder to give that a shot. I'm certain the front brakes are functionally 100% as when I bleed the rear brakes I still have half of a pedal. When I bleed the rear brakes the pedal goes to the floor, so I"m certain it's the rear line still has air in.

If its the Motive Power bleeder, be careful. The cap that came with the bleeder worked great, however, the factory master cylinder cap relieved all pressure at 5psi and blew brake fluid all over my car, while the cap was still installed! I ended up bleeding mine the old school way, although a set of speed bleeders front and rear made it a 1 person job.
