Makita 194992-4 (CB‑204) — Original Makita carbon brush set (Pair) , ready to restore motor contact and run-time on compatible tools. This set includes two carbon brushes (with springs) sized approximately 7 × 18 mm, designed to match the factory brush seats for a clean fit and reliable electrical contact.
Fits a wide range of Makita grinders, cut‑off and demolition tools and rotary hammers — for example GA7020, GA9020, GA9030, GA9050 and HM1304 among others — and is listed on Makita parts diagrams as the CB‑204 replacement for those models. Use it when brushes are worn, sparking heavily, or the motor loses power to bring performance back to specification.
Simple to install: the brushes come as a matched pair so you can replace both sides quickly and get the tool back in service. This is the original Makita brush set specified for the listed models, so it’s the direct fit recommended for repairing those tools.
