Overview
Designed to OEM specifications, these carbon brushes are essential maintenance items for brushed-motor power tools. Worn brushes cause excessive sparking, overheating, and can permanently damage the commutator if not replaced in time. This set provides a straightforward, cost-effective way to restore full power to your tool.

Compatibility
These brushes are designed for Makita power tools as listed in the compatibility section above. Verify your tool’s model number and brush part number before purchasing to ensure correct dimensions and lead configuration.
Installation notes
Always unplug the tool before replacing brushes. Access the brush holders on the motor housing and carefully extract each old brush. Insert the new brushes with the curved contact face toward the commutator. A brief break-in period at reduced speed helps the brushes conform to the commutator surface.
Common questions
Q: Will this 8PCS CB204/CB202 carbon brush set fit my Makita GA9020 and GA7040S angle grinders?
Yes, this brush set is made for the Makita models listed, including GA9020 and GA7040S, and it also fits GA7021, GA7011C, and HM1810. The easiest way to confirm is to compare your old brushes to the CB204/CB202 style and check that the shape, wire lead, and terminal match before installation.
Q: Can I use these brushes in my Makita HM1810 breaker hammer, or are they only for angle grinders?
These carbon brushes are compatible with the HM1810 as well as the listed Makita angle grinders. Since breaker hammers create a lot of dust and vibration, it’s a good idea to inspect the brush holders and commutator while replacing them to make sure everything is clean and wearing evenly.
Q: Do I need to replace all 8 brushes at once, and is there anything special I should do after installing them?
You only install one pair at a time in the tool you’re servicing, so the 8-piece set gives you multiple replacements. After fitting new brushes, let the tool run with no load for several minutes so the brushes can seat properly, and always replace both brushes together to prevent uneven motor wear.
