i just posted a topic about the same exact thing im just under 50k mileage and my pads are in great condition too. i also have the driver front sticking i believe (i thought it was wheel bearing for the longest time). i jacked it up on both sides and the one rotor spun while the driver front didnt suggesting too much pressure (obvious though it got so hot one time i burnt my finger on the wheel after driving).
when you pull into your drive way try and push your brake pedal and see if it gains resistance. mine does and (
How To Diagnose a Brake Problem | eHow.com ) says thats from brake fluid putting too much pressure on the piston creating our problem... ill tell you how it goes tomorrow
