What causes a breaker to go bad?

Age can cause parts to weaken, humidity or chemicals in the air can cause corrosion of internal parts and excessive tripping can cause them to wear out. I know Square D recommends turning the breaker off and back on once a year to exercise the mechanism to keep it working properly. There is also the quality issue, cheap parts wear out more quickly.

Yes they can go bad. Remember, you must fix the cause not the result. If your main is tripping then you have a dead short somewhere between the panel. If the breaker that is shot was not ever 'repaired' because of an electrical issue, you will continue to have issues.
