I have had stuck pins from rust, and one on the Buick that had no grease, clear never had grease. Also had a pad rusted in the yoke on Lin rear. On my Sable wagon, in my local driving I see ~130F or less. Maybe that is why I never wear out pads. I check my temps from time to time to see that they are the same side to side. Daughter's Buick had dragging brakes, like hot, under warranty, as the dealer OE pads they put on had burrs that stuck them in the yokes.
Dragging brakes use lots of gas. My opinion but it has to happen. I saw a case on a friends car where the pins were totally free but when the bolts were tightened, it was locked up. He bought a new yoke/caliper assembly and problem solved. He said his wife drove the car all the time and it had horrible gas mileage and the pads on one side lasted about a year. Pas side pads wear only, and on the outside only.
