It is possible that you have a warped rotor...this can push the pads back in the caliper as you drive, this will lead to the double pump situation.
A bent rear axle could do the same thing, it would make the rotor "wobble" in relation to the caliper. As long as the wobble is slight, the caliper can move with it and you may not feel it in the pedal, but when there is no pressure applied, it would knock the pads back.
