Milwaukee Tool CARBON BRUSH/SPRING

Carbon motor brushes are one of the most commonly replaced power tool components. Because carbon brushes are wear items; meaning that throuhg friction and use they will gradually wear away; they will eventually require replacement. Worn brushes are common causes of intermittent motor function; reduced electric braking; and reduced motor power. A worn out brush will often be worn down near the wire lead and may be cracked; pitted; or burned. When replacing carbon brushes; be sure to also inspect your armature for burns; cracks or other damage which indicates a larger motor problem.
