Has anyone else had this issue?

I noticed last summer that my MPG's were not getting better as the summer temps started to warm up. After taking the car on a 5-600 mi trip and getting 4-5 mpg less than expected I decided to try and figure out what was going on. I found the front driver side brake was clamping down hard on the caliper. I took everything apart greased the sliding pins, and compressed the piston. The piston was very hard to compress at first, but did loosen up. After doing this the MPG's came back to normal.

Last week I noticed again the MPG's dropping, and sure enough the caliper was stuck again.

Do I just need to put a new caliper on, or could there be anything else causing this problem?
