But the basic question is did it need brushes? (Probably not) - or did it just need a cleaning? Hit it with brake cleaner. The older models had 4 screws on the back and you could do a good cleaning otherwise - thru the ports with a straw. If you want to take it apart because you've got no other choice - these are by now (2024-1/2) worth $15 if they're working well. A set of brushes are more than that. Even if they're stinking and smoking if you can get to the stator without f'kg up your whole day - all you have to do is get the carbon out of the cracks - it's shorting there. Hopefully the brake cleaner will do a good enough job - expect 80%+. Happy day - you've got 4 screws to put back in. Go work.
