In case if the suspect is going to be the starter, then it should get unplugged from the car and taken to an automotive electrician where it can be tested. Most auto electricians will have brushes that they can supply and fit at a moderate price. However, check repair costs before you proceed because it might prove more cost-effective purchasing a new or reconditioned motor.
