At DMG Motorsports, we present the All Balls Racing Front Brake Master Cylinder Rebuild Kit (21-81103) for KTM — the smart, budget-friendly solution for riders dealing with a leaking, spongy, or underperforming front brake master cylinder. Rather than replacing the entire master cylinder assembly, this kit lets you restore factory-level braking performance by renewing the critical internal wear components that break down over time from heat, moisture, and everyday trail abuse. Backed by All Balls Racing's reputation for OEM-quality fit and finish, this kit is engineered to get your KTM's front brake feeling sharp and reliable again without the expense of a full replacement unit.

Features:

• Complete rebuild solution for leaking or worn front brake master cylinders
• Includes cup seals to restore proper hydraulic sealing and brake feel
• Copper washers included for a secure, leak-free banjo bolt connection
• O-rings included to seal critical mating surfaces and prevent fluid loss
• Replacement screws included where applicable for a complete, hassle-free rebuild
• Designed to bring braking performance back to like-new condition
• A cost-effective alternative to buying a full replacement master cylinder
• Engineered by All Balls Racing to meet demanding fit and performance standards
