At DMG Motorsports, we present the All Balls Master Cylinder Rebuild Kit (21-81023) — a purpose-built solution for restoring a leaking or worn front brake master cylinder to like-new condition. Rather than replacing an entire master cylinder assembly, this kit gives you every internal wear part needed to properly re-seal the unit, saving you money while getting your brake system back to full, reliable performance. This kit is engineered as a direct-fit rebuild solution and is commonly referenced for applications such as the Husaberg 450FE (2006-2008) front master cylinder, so be sure to confirm fitment against your specific model and year before ordering.
Built by All Balls Racing, a trusted name in powersports hard parts, this kit is manufactured to meet OEM specifications, ensuring correct fit, proper sealing, and dependable braking feel once installed. Everything required for a complete internal rebuild is included in one convenient package, eliminating the hassle of sourcing individual seals and hardware from multiple suppliers.
