What you are describing actually sounds normal to me. Your pedal will initially be soft and it will go to the floor as you pump the brakes after installing new pads until the pistons are firmly seated against the new pads and the new pads make contact with the rotors. Once that happens, your brake pedal should be hard. If I'm reading your post correctly, this is what is happening. Once you stated your pedal was hard, you didn't mention again the soft pedal that went to the floor.
Basically what happened is when you pressed in the caliper pistons to install the new pads, you placed the pistons all the way into the caliper housing. Upon pressing the brake pedal after installation, that piston has to reseat against the pads and then the rotors which is what caused the pedal to go to the floor.
Are your brakes STILL soft and spongy when depressing after SEVERAL pumps?
