Any cure for a sticky caliper other than replace it?

Here's what I'm experiencing tell me if it sounds like a sticky caliper.

I can drive for about ten miles with no shake. X5 feels fine. At around 12 miles X5 steering wheel begins to shake with increasing vigor to the point I have to pull off the road for fear of death. I hop out and notice the left front rotor is extremely hot compared to the others.

After the X5 sits for a while I can hop in and replicate the entire process. It will run fine for about ten miles and then the rotor gets extremely hot and the car shakes all over the place.

If the rotor was warped it would shake from the start of a drive wouldn't it?

The ten mile stretch has no stop signs, I never even put my foot on the break.

Could it be anything other than a sticky caliper?
