Description
Overview:
This genuine Husqvarna brake spring (part number 505 89 26-01 / 505892601) is a small but critical component of the chain brake assembly on petrol chainsaws such as the Husqvarna 135 and 140E. Made from durable spring steel with a corrosion-resistant finish, it provides the correct return tension for the brake mechanism so the chain can stop quickly and reliably when the brake is engaged. Replacing a worn, stretched, or broken spring restores positive brake action and helps maintain safe operation in everyday cutting tasks. Designed to fit specified Husqvarna models precisely, this OEM spring supports dependable performance and long service life as part of routine maintenance or a repair after impact or heavy use.
