BAD BRAKES: The Caliper Is Dragging

This comes from Reddit’s Subreddit Just Rolled Into The Shop. I have no idea how this can happen and neither did the poster who said the car was serviced by another shop. Some of the best comments were:

“That shop must not be of very high caliper.”

“Brakes are dragging a bit.”

“That’s the anchor for when you need to stop in puddles.”
