About This Product
For those maintaining the mechanical rear brake on a vintage Harley, this left-side brake shaft lever is a crucial component. It features the correct single-hole configuration for 1936 to 1957 Big Twin models, including Knuckleheads and Panheads. Designed to replace OEM 42556-36, this lever ensures that your brake linkage remains tight and responsive. Over decades of use, the original levers often suffer from wear at the pivot points, leading to a sloppy brake feel. Installing a fresh MCS replacement is a great way to ensure your classic stops as reliably as possible while maintaining the correct period-correct appearance.
Manufacturer part number: 900666.
