Makita 038213010 Spare Part - BRAKE SPRING DCS640/79 PS64/7
Original Makita part 038‑213‑010 — Brake spring for the chain‑brake assembly. This small, heat‑treated steel spring provides the return/tension force for the chain‑brake lever so the brake engages and releases reliably; it’s the stamped/formed coil that sits inside the chain‑brake mechanism and works with the brake plate and pawl.
Details: formed spring steel finished for corrosion resistance, shaped to sit against the brake plate (Makita part 038‑213‑040) and deliver a consistent spring rate when the hand guard is activated. The brake spring is a direct replacement designed to fit the brake/hand‑guard assembly without modification; the surrounding fasteners in the assembly use M3.5 × 9.5 mm screws.
Example compatible models (for reference): Makita DCS6400 / DCS6401 / DCS6421, DCS7300 / DCS7301, DCS7900 / DCS7901 (and the related Dolmar PS‑6400 / PS‑7300 / PS‑7910 that share the same brake components). Use this part when the chain brake doesn’t return, is loose, or the hand‑guard feels slack.
Why this part matters: a worn or broken brake spring prevents reliable brake engagement and is a common cause of a non‑responsive chain brake — replacing the 038‑213‑010 spring restores the original brake action and helps keep the saw safe to use.
