This saw that I have is about 1 1/2 years old. For what ever reason the braking mechanism has stopped working. Service shops here are running about 3 weeks. I need it now. In order to expidite I have changed the brushes, that had 1/2 the life still left. I tried to clean the field. I've tried swaping out the switch from a left over saw. Any oter suggestions.
