Genuine Makita carbon brush set (Pair) — part no. JM23000123 (also sold as CB-500). This is a matched 2-piece carbon brush replacement for brush-type motors used in Makita sliding and compound mitre saws; the brushes are supplied as the carbon blocks only (brush holders/caps are listed separately).
Typical compatibility includes models such as MLS100 / MLT100 / LS1018L / LH1201FL and M2300 — it’s the exact Makita-specified brush set for these saws.
Physical details: referenced as CB‑500, the carbon blocks are small, rectangular brush elements (listed dimensions about 17 × 6.5 × 13.5 mm on parts listings), supplied as a matched pair for even motor commutation.
Why this part: if your saw shows erratic motor performance, sparking at the commutator, or slow start/stop, replacing both carbon brushes with this original Makita set restores reliable electrical contact and helps prolong the armature and commutator life. As an original Makita replacement, JM23000123 appears in Makita parts listings for the models above.
