This video is a step by step process on how to check the brushes, disassemble the dryer to get to the rear motor, how to change the brushes, and reassemble and wire the dryer. If you own any of the K9 dryers please subscribe as I will be posting more videos on a variety of things with these dryers! Leave any questions in the comment section and I will try my best to answer them! In my spare time I do maintenance/service/repairs on any of the K9 brand dryers, so if you feel like the task at hand is a little to much for you, the link on my page will get you to my FB where you can message me for more info on the repair process!
