Full details
The Makita CB419 Carbon Brush Set is an essential maintenance component for Makita power tool owners looking to extend the service life and maintain optimal motor performance of their equipment.

FAQs
How do I know if my tool needs new brushes?
Common signs include excessive sparking in the motor housing, intermittent power, or a noticeable drop in power and torque.
Should I replace one brush or both?
Always replace carbon brushes in sets. Replacing only one can cause uneven electrical load and accelerated wear on the motor.
Are these brushes compatible with every Makita tool?
No. The CB419 is designed for specific models. Always check your tool's parts manual or search by the tool's model number.
Do I need special tools to replace them?
Generally, only a flat-head screwdriver is required to remove the brush caps.
How often should I check the brushes?
Under professional or heavy usage, inspect them every 50-100 hours of operation. For occasional home use, a yearly inspection is sufficient.
Troubleshooting
Tool still experiences power loss after replacement
Check the condition of the commutator for heavy scoring or pits; if the commutator is damaged, the new brushes will wear out prematurely.
Brush cap will not seat correctly
Verify that the spring is fully compressed and that no debris is obstructing the brush channel in the housing.

Setup, Compatibility & Care
Before installation, always disconnect the tool from the power source or remove the battery pack to prevent accidental startup. Locate the brush caps on the exterior of your tool housing, unscrew them using a flat-head screwdriver, and extract the old brushes. Check the condition of the spring mechanism and the internal brush holder for any debris or buildup. Insert the new CB419 brushes, ensuring they slide freely and the springs are seated correctly. Always replace brushes in pairs, even if one appears to have more life left than the other, to ensure balanced electrical distribution. Avoid applying lubricants to the brushes, as they are designed to operate dry.
