Alum Tandem M/C .875in Bore

The Alum Tandem M/C .875in Bore master cylinder from Wilwood is designed for serious brake system upgrades, making it ideal for custom vehicles, race applications, and high-performance street builds. This tandem design provides independent braking force to front and rear circuits, essential for builders seeking effective modulation and stopping power.

Constructed from aluminum, this master cylinder maintains a compact footprint of 5.3 x 5 x 13.5 inches while ensuring reliable fluid displacement across both circuits. The 0.875-inch bore diameter allows for effective tuning of front-to-rear bias when paired with proportioning valves, enhancing brake balance compared to OEM single-circuit units.

This lightweight design, weighing just 3.4 pounds, helps reduce the overall weight of the vehicle while providing the necessary thermal stability for performance applications. It integrates seamlessly with modern Wilwood brake kits and can be adapted into existing custom brake lines and proportioning valve setups, making it a versatile choice for restorers and fabricators.
