Why do generator brushes wear out?
Low Spring Pressure: Inadequate spring pressure can cause rapid electrical brush wear. Clock and finger style springs tend to lose force as the brush wears, and all springs will fatigue over the course of time. This will reduce the effective force at the brush face and increase the rate of brush wear.

Why do brushless motors last longer?
Longer-lasting.
No friction in a brushless drill means less wear and tear, and less heat. “Excessive heat is the enemy of both the motor and the battery,” says Wayne Hart, communications manager at Makita. “And a brushless motor runs up to 50 percent cooler than a brushed motor.”
