I have an old Bosch CSB 500 RLE drill which has given years of service but lately it has started to play up. When I pull the trigger sometimes it works and sometimes not. I opened it up and it seems like the carbon brushes have worn down. They are only about 3-4 mm thick and look very short compared to a photograph of some new ones I saw on the Net. Do you think I'm right in my diagnosis of the problen and is replacing the brushes just a question of pulling the old ones from their plastic housing and pushing in the new ones?
There's a photo of the brushes here
