Hi Daniel,
Since your application is low power, I E Not several tens of amps, You might consider carbon brushes, I think Home Depot may sell them or LOWES as general purpose replacements for motors.

Whilst you can certainly use carbon brushes, they are typically used where high currents in the tens to hundreds of amps are required. A good example is the starter motor in a motor vehicle.
