Alum Tandem M/C 1.00in Bore Black

The Wilwood Alum Tandem M/C 1.00in Bore Black is a professional-grade aluminum master cylinder designed for high-performance hydraulic brake systems in motorsports and custom vehicle applications. This tandem configuration delivers dual-circuit braking control, a critical safety feature that maintains stopping power even if one brake line fails. Built for vehicles requiring precision hydraulic management, this master cylinder serves restoration shops, race teams, and custom builders who demand reliability under demanding conditions.

Engineered with a 1.00-inch bore and 1.100-inch stroke, the Wilwood tandem master cylinder generates consistent hydraulic pressure across front and rear brake circuits with its integral reservoir design. The aluminum construction minimizes weight while maintaining structural integrity, a key advantage in performance builds where unsprung mass directly impacts handling and braking response. The black powder-coated finish protects against corrosion while delivering a clean OEM-style appearance suitable for both street and competition applications. The tandem design ensures proportional brake force distribution, preventing lock-up and improving pedal modulation during hard braking events.

This master cylinder is ideal for custom hot rods, vintage car restorations, track-focused performance vehicles, and street machines requiring modern brake system architecture. The integral reservoir eliminates the need for separate fluid containers, simplifying installation and reducing plumbing complexity. Weighing 3.23 pounds with compact dimensions of 5.6 × 5.15 × 10.35 inches, it mounts easily in tight engine bays without sacrificing brake system performance. Installation typically requires integration with compatible calipers and brake lines; consult Wilwood's system compatibility charts to ensure proper pairing with your vehicle's specific brake setup.
