What are the symptoms that indicate that the motor brushes are close to replacement time?

On the Ego scooters, by the time the symptoms came on, the commutator had been scored or damaged.

On one Ego motor, a section of the commutator fell out, making some odd noises. The motor was still used for months, albeit at a crippled performance.
