Carbon brushes are the most frequently replaced power tool parts. Since carbon brushes are wear resistant items, this means they gradually wear out through friction and use and eventually need to be replaced.
Worn brushes are a common cause of intermittent motor function, weakened electrical braking, and reduced motor power. If there is rapid or asymmetric carbon brush wear, it indicates an issue with the motor's rotor, not a quality problem with the carbon brushes themselves.
