Your on the right track, replace the breaker. Breakers are mass produced and you will often find one that will not work correctly after tripping or being turned off and several times. Also a breaker can be damaged when it trips and as such manufacturers will not warranty one which has been tripped because there is no way to tell how much short circuit it has taken.
Yup, replace the breaker.
Or just swap it with another one in the panel that has the same rating and see if the problem follows the breaker. Then you'll know.
+1 on the Swap.
Don't F around with the Buss Bars. :huh Dead front is best if you can.
Yeah, they go bad after a number of trips. Often, they won't even reset after one good trip.
Saw a store owner try to reset a breaker that had a dead short still on line. He reset it several times only to have it trip. Then he reset it and HELD IT. It stuck closed no doubt because the contacts were welded shut. Then we heard a lot of shouting from the back room where the short was. Took an electrician most of the day to fix the melted wires.
