Brakes are back - Thanks!
I just replaced a leaking master cylinder and did a full bleed of the brakes. No more leaks or spongy peddle. I used the search here to learn before I started. In particular, LEVE and JEEPN had great advice. I ended up replacing the bleeder screws (all came loose with PB Blaster) with speed bleeders and then used the MityVac.
