Alum Tandem M/C Kit w/ Brkt & Prop Valve 1.12in

The Alum Tandem M/C Kit w/ Brkt & Prop Valve 1.12in by WILWOOD is a complete brake proportioning solution designed for custom and street performance vehicles requiring dual master cylinder setups. This tandem master cylinder kit addresses the needs of builders working with independent front and rear brake systems, or those upgrading to modern hydraulic braking geometry on classic platforms. Whether you're fabricating a custom hot rod, converting a vintage build to modern safety standards, or integrating separate front and rear circuits, this integrated package eliminates the guesswork of sourcing compatible components individually.

Built from lightweight aluminum construction, the Alum Tandem M/C Kit delivers the rigidity needed for reliable brake modulation while minimizing added weight—critical in performance applications where unsprung mass impacts handling. The 1.12-inch bore specification strikes a balance between pedal feel and hydraulic pressure delivery, providing proportional braking response across split systems without excessive pedal travel or excessive pressure spikes. The integrated proportioning valve manages pressure distribution between circuits, preventing rear-wheel lockup and maintaining balanced deceleration across varied load conditions. The included mounting bracket ensures secure installation and correct pedal geometry alignment, while the prop valve hardware handles pressure regulation so your brake lines and wheel cylinders receive properly balanced flow.

This kit benefits fabricators, restoration specialists, and DIY enthusiasts tackling dual-circuit brake conversions where OEM master cylinders won't fit or won't provide proper pressure balance. Installation requires brake line routing experience and understanding of hydraulic proportioning principles, making it ideal for builders with mechanical depth or those working with a qualified brake shop. The compact dimensions and integrated design simplify under-dash or firewall mounting in tight custom engine bays. Verify your brake line thread sizes, proportioning adjustment range, and mounting surface clearance before ordering to ensure proper fitment with your specific brake circuit layout and wheel cylinder bore specifications.
