Alum. Tandem M/C Kit w. Brkt Prop Valve 15/16in

The Wilwood Aluminum Tandem M/C Kit with Bracket Proportioning Valve (15/16 in bore) is a professional-grade hydraulic braking component engineered for high-performance motorcycles and custom builds requiring precise brake modulation. This tandem master cylinder kit delivers the reliability and responsiveness demanded by riders who need superior stopping power and control under demanding riding conditions. Built with a 1.10 in stroke and integral reservoir, this assembly provides the foundation for a responsive brake system capable of handling both street and sport applications.

Constructed from lightweight aluminum with black paint finish, the Wilwood aluminum tandem master cylinder reduces unsprung weight while maintaining exceptional strength and corrosion resistance. The 0.938 in bore diameter is precisely calibrated to deliver optimal hydraulic pressure distribution across dual brake circuits, ensuring balanced braking force and enhanced safety margins. The integral reservoir design eliminates external fluid containers, streamlining installation and reducing complexity. The included proportioning valve (15/16 in) regulates pressure ratios between front and rear brake circuits, preventing wheel lockup and ensuring predictable brake feel across varied riding scenarios and brake pad wear conditions.

This master cylinder kit is ideal for motorcycle builders, restoration specialists, and riders upgrading to modern brake systems on classic or custom platforms. The compact footprint (12.38 x 5.63 x 12.38 in) and 6.1 lb weight make it suitable for a range of frame geometries without requiring extensive modification. Installation typically involves mounting via the included bracket and connecting DOT-approved brake lines to existing wheel cylinders or calipers, making it compatible with both drum and disc brake configurations depending on system design.
