My miter saw brake started acting weird yesterday and by the end of the day was making a banging sound when I let off trigger. It sounds like rocks banging around in the motor. I found a post where someone had a problem like this and they were told either the trigger or brushes needed to be replaced. Has anyone had a similar problem? Is there something specific to look for? I don't want to take it apart without a clue as to what to look for
Thanks
