replacement brushes for sunroof motor E-class

[Leylandp76]

My sunroof motor is pretty erratic so, feeling brave, I took it out to see what was wrong with it. As suspected, it needs new brushes.

Does anyone know where I can get new brushes - preferably online? The motor is a Bosch 0 390 251 696 CHP.

I would guess most Bosch motors (windscreen wipers etc) probably use the same brushes...

Thanks
