Silver - I did the same with using a small vise. It improved the door check from not holding at all, to holding it open. The slot that the spring-steel collar slips in, is not supposed to be "U" shaped, but be slightly necked in at the opening. The tip of bracket's opening probably wears.
I'd advise anyone doing this to take the bracket down and very carefully squeeze the Thumb shaped protrusion with a large metal vice. Why I say carefully is that if the Thumb is bent inward too much, you will be throwing away the bracket. With a large metal vise, I would suggest to squeeze the bracket ever so slightly, take out of the vise and check its operation. If still loose, squeeze a little more. By doing this in mini-steps you can avoid over bending and destroying the bracket.
