2002 Volkswagen Passat Brake pedal wont come back up

Brakes problem
2002 Volkswagen Passat 4 cyl Front Wheel Drive Automatic 60 000 miles

Installed new front pads and rotors, when I finished I started the car, pushed the brake pedal to the floor to set the pads, and it stayed there.
I manually lifted the pedal with my hand, it came up, pumped it a couple more times and seemed to get a pedal.
I put the car in gear tried and to backup, realizing that the brakes had not realeased I pulled the car back inside and lifted it back up.
That is when I noticed the brake lights were still on.
Checked the wheels and found that the brakes were on all 4 wheels.
The brake pedal is presently sitting about half way to the floor.
I can lift it up with my hand and it realeases.
When I let the pedal go It goes back down to about half way and all 4 wheels will not turn.
