At DMG Motorsports, we present the All Balls Racing Rear Brake Master Cylinder Rebuild Kit (SKU 21-81095) — the trusted solution for restoring a weeping or worn-out rear master cylinder to like-new performance. Instead of paying for an entirely new master cylinder assembly, this rebuild kit gives you every wear component required to re-seal your unit and get your braking system firm, responsive, and leak-free again. All Balls Racing has built its reputation on offering the industry's most comprehensive line of bearing, seal, driveline, and suspension kits for on-road and off-road machines, and this master cylinder kit continues that standard of quality and precision fit.

Whether your brakes have developed a spongy pedal, a slow fluid leak, or inconsistent stopping power, worn internal seals inside the master cylinder are often the root cause. This kit contains all of the components required to re-furbish one master cylinder, so you can rebuild the unit you already have rather than replace it outright — saving time and money while restoring OE-level function.

Features:

• Complete rebuild kit designed to re-seal a leaking rear brake master cylinder
• Includes cup seals to restore proper hydraulic pressure and sealing
• Copper washers included for a secure, leak-free banjo bolt connection
