The Wilwood Alum Tandem M/C Kit with Bracket and Proportioning Valve is engineered for builders and enthusiasts serious about brake system upgrades on custom vehicles, hot rods, and high-performance street machines. This tandem master cylinder assembly delivers the hydraulic pressure distribution and modulation control required for responsive braking on modified platforms where factory brake systems fall short. Whether you're running a tube-frame chassis, custom engine bay, or converting to a modern brake setup, this kit provides a complete foundation for a reliable dual-circuit braking system.
Built from lightweight aluminum, this tandem master cylinder reduces unsprung weight while maintaining the structural integrity needed for high-pressure applications. The integrated proportioning valve balances front-to-rear brake bias, preventing rear-wheel lock-up under hard braking and ensuring predictable pedal feel across varying load conditions. The 7/8-inch bore size strikes an ideal balance for street-driven customs, offering adequate displacement for responsive pedal response without requiring excessive lever travel. Wilwood's precision-machined design ensures consistent sealing and durability through thousands of heat cycles, critical for vehicles pushed hard in weekend driving or track environments.
This kit appeals to fabricators, custom builders, and performance mechanics upgrading vehicles where OEM master cylinders don't fit the new suspension geometry or brake layout. The included bracket simplifies mounting flexibility, allowing integration into non-standard engine bays and frame configurations common in restoration projects and tube-frame builds. Compatibility depends on your specific caliper selection and hydraulic line routing, so confirm your brake line diameter and proportioning valve settings match your front and rear caliper combinations before assembly. With proper bleeding and system setup, this master cylinder assembly forms the pressure-generating core of a street-capable or weekend-warrior braking system.
