Alum Tandem M/C Kit w/ Brkt & Prop Valve 1in

The Wilwood Alum Tandem M/C Kit with Bracket and Proportioning Valve (1 inch bore) is a complete master cylinder assembly engineered for high-performance hydraulic brake systems. This kit serves as the core component in custom brake builds, restoration projects, and motorsport applications where reliability and precise pressure control are essential. The tandem design provides independent hydraulic circuits for front and rear braking, a critical safety feature that ensures failsafe operation even if one circuit sustains damage or fluid loss.

Constructed from lightweight aluminum, this master cylinder reduces unsprung weight while maintaining structural integrity under demanding brake pressures. The 1-inch bore diameter delivers responsive modulation and consistent pedal feel, complemented by a 1.100-inch stroke that provides adequate fluid displacement for full brake system engagement. The integral reservoir eliminates external fluid lines in that area, streamlining plumbing and reducing potential leak points. Wilwood's proportioning valve regulates pressure distribution between front and rear circuits, preventing rear-wheel lockup during hard braking and enhancing vehicle stability and stopping performance across varying load conditions.

This complete kit is ideal for fabricators, restorers, and performance enthusiasts building custom brake systems for street rods, classic cars, race vehicles, and specialty automotive projects. The included bracket facilitates straightforward mounting to various engine bay configurations, while the proportioning valve ensures balanced braking balance without requiring separate adjustment. Installation requires proper brake line routing and DOT-approved fluid, and compatibility should be verified with your specific vehicle's brake caliper specifications and total system displacement requirements.
