If they are the same, then the caliper is conected via slider pins, it could be either the caliper or one ore both slider pins that are, or were siezed.
The fact that you say it was OK on the way home suggests that it was not fully siezed but tight. I would still be inclined to remove the pins, clean up everything, a twist drill of the correct size is good for cleaning out the bore for the slider pins, lubricate with silicone grease or High temp grease NOT COPA GREASE. Also I would press the caliper piston back in a couple of turns with a "G" clamp, unwind a couple of turns, leave the "G" clamp in position and pump the pedal till it goes tight (the piston will have come up to the pad on the clamp). Do this several times, or until it is noticably easier to wind back in, asuming it was tight in the first place.
All this asumes that you are confortable working on your brakes of course.

Many thanks. That all makes sense.
