Brakes dragging

While i was driving, I noticed my car was a little sluggish, and the steering wheel began to shake, when i got were i was going (about a 10 mile drive) there was a real strong smell coming from the brakes, when I got out of my car the front driver side brake rotor was smoking. I'm going to assume the wheel shaking came from the rotor warping. I haven't had a chance to look into it yet. Any ideas why the brakes would drag on just one wheel?

The car is an '01 GT

take the calipers off and check the pins. Alot of times people do not re-grease them after doing a brake job, and they cause the caliper to stick

Also make sure the rubber bushing on the caliper slide pin is not swollen and hard to slide in and out. Napa carries those for a few bucks. Another thing is to make sure the pads are not extremely tight in the bracket. I have seen a lot of pads that had to be hit out with a hammer because they were either seized to the hardware or they just did not fit right to begin with. Sometimes you have to grind a little paint off of the edge of the brake pad backing that slides into the bracket.
