[V6-12v] Brake Bleeding

[dcooke at npacc.net]

I replaced the rear calipers/pads this weekend and bled all 
4 corners.  The brake pedal still feels soft on the first application
and gets stiffer on each successive application.  Did
I miss a bleeder valve somewhere or do I continue to try
and bleed again.  I used the method of having someone pump
the brake pedal since I do not have any pressure equipment
to do it by myself.
