At DMG Motorsports, we present the All Balls Racing Front Master Cylinder Rebuild Kit (21-81162) — a precision-engineered seal kit designed to bring a leaking or worn-out front brake master cylinder back to like-new condition. Built as a direct replacement for Harley-Davidson OEM number 42862-06B, this kit is the go-to solution for riders looking to restore firm, reliable braking feel on their Touring model without the expense of a full master cylinder replacement. All Balls Racing kits are trusted throughout the powersports industry for delivering OEM-quality fit and function at a fraction of the cost of new components, and DMG Motorsports is proud to make this essential rebuild kit available to our customers.
