Makita CB-105 Carbon Brush

CB-105 uses high-quality carbon material for efficient power transfer, designed for a precise fit with Makita tools. It emphasizes durability, enhanced electrical conductivity, reduced friction, easy replacement, broad compatibility across Makita models, and protection of the motor from wear.

CB-105 is designed to work with a wide range of Makita tools that use standard carbon brushes. For exact compatibility with your model, compare the tool’s brush part number and consult the Makita-compatible listings on Fepy. This brush is intended to fit Makita motors that require a CB-105-type carbon brush.

CB-204 and CB-105 are both carbon brushes used in Makita tools, but they differ in size, fit, and model compatibility. CB-204 is a different variant optimized for certain Makita models, while CB-105 is tailored to others.

CB-122 is another Makita carbon brush variant with its own fit and model range. Compared to CB-105, it targets different tool designs and motor configurations. For a direct comparison, see the Makita CB-122 Carbon Brush page here: https://fepy.com/product/makita-cb-122-carbon-brush

Use CB-105 when you notice reduced motor efficiency, irregular tool performance, or signs of brush wear such as arcing, intermittent power, or tool slowdown. Replacing worn brushes helps restore consistent power delivery and extends the life of the tool’s motor.

To replace CB-105: unplug the tool and remove the brush cover, disconnect any wiring from the old brush, carefully extract the worn carbon brush and spring, insert the new CB-105 with correct orientation, reseat the spring, reconnect wiring, and reassemble the tool. After replacement, test the tool at low speed to ensure smooth operation.

Safety steps include unplugging or removing the battery, wearing eye protection, handling brushes with clean hands to avoid contamination, avoiding contact with the commutator, and ensuring the tool is completely powered down before starting. Work in a clean, well-lit area to prevent debris from entering the tool.

CB-105 provides stable electrical contact between the motor’s commutator and rotor, reduces arcing, lowers brush wear, and minimizes friction. This helps maintain consistent power output, reduces heat buildup, and slows motor wear, contributing to smoother operation and better tool efficiency.

The lifespan of CB-105 varies with usage, load, and operating conditions. In typical DIY or professional use, it should provide a reliable service period before replacement is needed. Higher loads, frequent overheating, or dusty environments can shorten brush life, while proper maintenance can extend it.

Yes. Replacing worn CB-105 carbon brushes is a cost-effective way to restore tool performance and extend motor life, often saving the cost of more extensive tool repairs or replacements. Regular maintenance with genuine CB-105 parts helps maximize return on your Makita tools.

To extend CB-105 life: keep tools clean and free of dust, avoid overheating by using the tool within recommended duty cycles, replace brushes in pairs when applicable, store tools in dry environments, and perform periodic checks for wear or damage. Using genuine replacement brushes like CB-105 also helps maintain consistent power output.
