Good to know you have the problem identified.

It shouldn't be a problem. The rubber elbow routes air from near the fan
where the pressure is high through the elbow and directs it on the
brushes. I would guess that it cools them and blows off dust and dirt.

I would like to find some replacement brushes. I didn't ring

Doubt that dealer will have brushes. Only sell the whole motor assembly.
You could take the motor to an electric motor repair shop to get them
replaced. I have heard of people finding generic brushes at local
hardware stores and installing them. Still taking the fan assembly out
will be a bit of a job so I would suggest letting a shop replace the
brushes just to be sure.

Glad you found it.
