2003 Ford E-Series Van pulling to left while braking

Brakes problem
2003 Ford E-Series Van V8 Two Wheel Drive Automatic

I recently had my front brakes done on my 2003 e250 Ford van. The garage installed new pads, turned the rotors, and flushed the brake system. I have approximately 43,000 mi. On my truck. Since having my brakes done, rears included, my van pulls to the left while braking. My van must be warm first, but man does it pull.
