OKODOKO Carbon Brushes - Cb-407

You should consider replacing your carbon brushes when you notice a significant decrease in tool power, intermittent operation, excessive sparking, or if the tool stops working altogether. Visual inspection will show them getting shorter over time.

No, these CB-407 brushes are designed for specific Makita models listed in the product description (e.g., JS8000, BO5030, HP2050, HR2475). Always check your tool's manual or confirm compatibility before purchasing.

This product is a 4-pack, meaning it contains four individual carbon brushes.

These brushes are specifically manufactured and tested for compatibility with certain Makita power tools. Using them in non-Makita tools is not recommended and could lead to tool damage or poor performance.

The lifespan of carbon brushes varies greatly depending on the tool, usage intensity, and operating conditions. They are considered wear items and will eventually need replacement.

Typically, only basic tools like a screwdriver may be needed to remove brush covers. Ensure you have the correct replacement brushes and follow safety precautions.

Ensure the tool is properly plugged in and the power outlet is functional. Double-check that the new carbon brushes are correctly seated and making firm contact with the motor's armature. Verify that no internal wires were dislodged during replacement.

Confirm the new carbon brushes are fully seated and making consistent contact. Check for any debris or obstruction in the brush holder. The issue may also stem from other worn components if replacement doesn't resolve the problem.

Some sparking is normal, but excessive sparking can indicate worn brushes or a damaged armature. Ensure the new brushes are the correct type and are properly making contact. If sparking persists and is severe, the motor may require professional inspection.
