Description
Overview:
This Brake Spring is a genuine Husqvarna component used in the chain brake assembly of petrol chainsaws. Made from tempered spring steel for high fatigue resistance, it provides the return force that engages and resets the brake mechanism, helping the chain stop quickly and reliably when the brake is applied. It is a direct replacement for OEM No. 501 87 54-01 and is suitable for a range of Husqvarna saws, including the 242 and 246. Fitted inside the clutch cover area, the spring works with the brake lever and band to maintain correct tension and consistent braking action. Ideal for professional and domestic machines, it restores safe operation when the original spring is worn, stretched, corroded, or broken. This is a Genuine Part from Husqvarna.
