Genuine Makita replacement part Set of 2 Carbon Brushes with wire lead attached. • Worn brushes are often the cause of a poorly running motor • Replacing brushes can fix an intermittent motor • New brushes can restore a motor's electric braking Carbon motor brushes are one of the most commonly replaced power tool components. Because carbon brushes are wear items, meaning that through 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.

Very easy to replace and fit perfectly!
These appear to be the correct carbon brush and the removal of the old ones was easy and installing the new ones was too! A lot cheaper than buying another $90 grinder!
