I own a Dyson DC 23 vacuum cleaner. One day it's brush stopped. Some tooth wheel inside was broken. It is expensive thing (it costs about 100$ here), but I had no choice. I ordered a new brush. It worked about a month and broke again. There is no warranty on brush. And it made from plastic.
After detailed examination I found a broken pin beside the connection to tube. It is sort of limiter that holds brush inside the vacuum tube. And there is a solution that come after brainstorming.
Allen screw in place of the pin, strengthened by "Loctite" (You can see it at the picture center). The brush works again.
