FAQs
How often should I replace these carbon brushes?
Replacement frequency depends on usage. Inspect them regularly, especially if you notice a drop in power or increased sparking. For heavy use, they might need replacing every few months; for light use, possibly annually or longer.
Are these brushes compatible with models other than the ones listed?
No, the OKODOKO Cb303 brushes are specifically designed and tested for Makita models 9403, 9404, 9921, 9903, and 9920 only. Using them in incompatible models can cause damage.
What does 'consumable item' mean for carbon brushes?
It means they are designed to wear down over time with normal use, similar to how a tire wears down. They are a necessary part that eventually needs replacement to keep the tool running.
Can I install these myself?
Yes, replacement is generally straightforward and can be done with basic tools. If you are uncomfortable with DIY repairs, consult a professional.
Do these brushes come with springs?
Yes, these brushes are typically designed to work with the existing spring mechanism in your Makita sander's brush holders.
What happens if I don't replace worn carbon brushes?
The tool's performance will degrade, leading to reduced power, potential stalling, and increased sparking. In severe cases, continued operation with worn brushes can damage the sander's motor commutator.
Troubleshooting
Sander loses power or stops intermittently.
The carbon brushes are likely worn out. Replace them with new OKODOKO Cb303 brushes.
Excessive sparking from the motor housing.
Worn or damaged carbon brushes can cause excessive sparking. Replace the brushes.
New brushes don't fit properly.
Verify that your Makita belt sander model is listed as compatible (9403, 9404, 9921, 9903, 9920). Ensure you are using the correct OKODOKO Cb303 part.
Difficulty removing the brush caps.
Use a flathead screwdriver to gently pry or unscrew the caps. If stuck, a small amount of penetrating oil might help, but ensure it doesn't get into the motor.

Setup, Compatibility & Care
Compatibility: This set of OKODOKO carbon brushes is designed specifically for Makita belt sander models: 9403, 9404, 9921, 9903, and 9920. Ensure your model number matches one of these before attempting installation.
Setup:
- Disconnect Power: Always unplug the belt sander before performing any maintenance.
- Access Brushes: Locate the brush caps on the side of the motor housing. These are usually small, round covers.
- Remove Old Brushes: Unscrew or pry off the brush caps. The old carbon brushes may slide out or require gentle wiggling. Note their orientation.
- Install New Brushes: Insert the new OKODOKO Cb303 brushes, ensuring they are seated correctly and oriented as the old ones were. The spring mechanism should apply even pressure.
- Replace Caps: Screw the brush caps back into place.
- Test: Reconnect power and briefly run the sander to ensure it operates correctly.
Care: Carbon brushes are wear items and cannot be "cared" for to extend their life beyond normal use. Regular inspection during belt changes is recommended. If you notice excessive sparking or reduced power, it's time to replace them. Clean any dust buildup around the brush holder area when replacing.
