In Stock
Carbon Brush Set
Part #CB325
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.

This is a Push-Button type switch that has 4 terminals, 2 internal and 2 external. This genuine Makita replacement part is sold individually. rnrnSwitches are commonly replaced parts in tools. A switch handles on/off and variable speed operations. They also have a role in electric breaking; they can momentarily reverse electrical polarity. Because switches use mechanical internals, they will degrade and wear out over time, eventually needing replacement. Some common signs of a broken or failing switch are as follows: • The tool has completely stopped functioning - it will not start. • The tool operates intermittently, requiring multiple tries to turn on, until eventually it won't start at all. • The variable speed function and electric braking aren't working properly.
