glang Posted October 16, 2016 Share Posted October 16, 2016 Anybody got any idea how many miles dynamo brushes last? Ive still got the originals in my Vitesse and just wonder when they might need changing... Quote Link to comment Share on other sites More sharing options...
mazfg Posted October 16, 2016 Share Posted October 16, 2016 Best thing is to have a look at them. Quote Link to comment Share on other sites More sharing options...
glang Posted October 16, 2016 Author Share Posted October 16, 2016 hmmmmm I prefer not to fiddle with things that are working perfectly. Ive bought replacement brushes just in case - do they fail suddenly or is there some warning and is it much of a job to change em? Quote Link to comment Share on other sites More sharing options...
scotty71 Posted October 16, 2016 Share Posted October 16, 2016 if the dynamo is charging ok, i would leave them alone. you can see if they are getting smaller, by putting a ruler along side them. the modern brushes are softer, and were out quicker.
