My brakes have been a bit soft for a while, (one pump of the pedal would
firrm them up), so I tried bleeding them today.  I used a vacuum bleeder kit
and did them in order from farthest to nearest the master cylinder.  I used
fresh DOT 4 fluid to keep the Master cylinder resevoir above the min. line.
I bled each wheel until I got clear, clean fluid.  I closed each bleeder
while vacuum was high to ensure no flow back. I used about a 1/2 pint of
fluid.

Now my brakes are softer than before.  What did I do?

Master was rebuilt last year and rear wheel cylinders were replaced last
year too.

Pedal is kind of mushy until about 2/3 down where it feels and sounds like
it hits something solid.  It goes a bit further but is much firmer. Real
braking only starts when it gets to this firmer point.

Help!
