1 1/16in Tandem Master Cylinder Kit

The Wilwood 1 1/16in Tandem Master Cylinder Kit (Model 260-4894) is a purpose-built hydraulic brake master cylinder designed for high-performance braking systems requiring independent dual-circuit architecture. This tandem master cylinder kit delivers the dual-reservoir integration and direct-mount configuration that serious brake builders and restoration specialists rely on when upgrading or rebuilding complete braking systems for street rods, performance vehicles, and vintage car restorations.

The cylinder features a 1.063-inch bore paired with a 1.350-inch stroke, engineered to provide proportional pressure distribution across dual brake circuits while maintaining responsive pedal modulation. The aluminum construction with natural finish keeps weight minimal—critical for performance applications—while the integrated direct reservoir design eliminates external fluid lines and reduces potential leak points. This tandem configuration allows independent circuit operation, ensuring that loss of pressure in one circuit does not compromise complete braking function, meeting reliability requirements for both street and track use.

This master cylinder kit addresses the needs of enthusiasts and professionals who demand precision hydraulic braking with reduced complexity. Whether upgrading a classic restoration, building a custom hot rod brake system, or replacing a worn factory master cylinder with a performance alternative, the Wilwood tandem design provides the mechanical advantage and fail-safe redundancy expected in modern brake systems. The kit format includes all necessary components for direct installation, making it ideal for those who prioritize engineering integrity over off-the-shelf convenience.
