Tim,
Sounds like it could be rotor runout. If the rotors "wobble" they will push
the pistons back into the caliper too far, then you have to push twice; once
to get them back in range or touching a bit, once to do the real braking. In
between of course they can lget pushed back in a little.
This assuming that you can sit in the garage and mash the pedal and hold it
for a time without it going down. It should be a firm pedal pretty quickly.
In other words, not a lot of travel once the pads get to the rotor. If not,
could be more air in their yet compressing easier than the fluid.

I just bled the brakes on my 70 2000 again. The pedal seemed better at first
but once I had the car on the road it was soft and needed to be pumped to get
a decent feel. I have what look to be new pads on the front.
Do I still have air in the line(s)? Any thing else it might be?
Tim
