Ford Repair: 97 mercury villager van, spongy brakes, mercury villager, spongy brakes

Question
Hi, I have had for some time a spongy pedal.  I replaced both rotors and pads on the front.  Checked back brakes (still has about 1/4" pad left, drum looked good) and adj. those.  I had a spongy feel before, and still do.  I replace the master cylinder with a new one (not remanufatured) bench bleed the master cyliner and then bleed the entire system again.  Seems no matter what i do, I can't get rid of the spongy pedal.  I have bleed the system enough that it now has all new brake fluid.  I read that the ABS may need to be bleed as well by a computer and tech.  any info would be appreciated.  I don't have an ABS light and I did verify the the ABS is working by doing a hard stop on dirt.  The ABS light works, but is not light when the car is running, so i assume there is not a problem with the ABS.

thanks


Answer
i would make sure that the pads are postioned right and check that the shoes are on the wheel cylinders, make your your slides are free on the calipers and i would just crack open the bleeders and gravity bleed , what u do is start at the r/rear crack bleder and let flow on its own for about 45 secs, then l/rear then r/front then l/front see how that helps
