Sebo Carbon brush set for power nozzle motor

I bought these to replace the worn out motor brushes in my Sebo X4. However, these brushes needed to be modified to fit. They dont come with the plastic mounting cartridge, and the original brushes were glued/fused into the original cartridges. I had to carefully drill and break the old cartridges to remove the worn brushes. Then I inserted the new brushes into what was left of the old cartridges.
