will not increase the efficiency.

Replacing carbon brushes

When the resin insulating tip inside the carbon brush is

exposed to contact the commutator, it will automatically shut
off the motor. When this occurs, both carbon brushes should
be replaced. Keep the carbon brushes clean and free to slip
in the holders. Both carbon brushes should be replaced at

the same time. Use only identical carbon brushes.
