There are two pistons, if that answers your question.
Two pistons per side? Without a car in your sig or bio its hard to tell what we are talking about. But yes, generally a sign of rust.

When I bought my 1980 300TD the PO told me you could only drive it a few miles before it would over heat and die. Diesel die? Hardly. But yes, it did. Because the calipers were rusted and the rotors would expand due to dragging calipers. Eventually they would get so hot and so much resistance would build that the engine would die.

The dealership told her it would be a new injection pump and cost $1200.....
