Master Cyl Tandem 15/16 Compact Black

The Wilwood Master Cylinder Tandem 15/16 Compact Black is a compact dual-circuit master cylinder engineered for custom brake system integration where space is limited. With its 15/16-inch bore diameter and 1.100-inch stroke, this aluminum tandem master cylinder delivers proportional hydraulic pressure across front and rear brake circuits simultaneously, making it ideal for hot rod builds, restoration projects, and custom brake applications where OEM components don't fit the intended platform.

The integrated reservoir eliminates the need for a separate external tank, reducing under-hood complexity and installation footprint. The compact profile—measuring 5.44 x 5.13 x 13.5 inches and weighing just 3.23 lbs—enables fitment in tight engine bays where a standard master cylinder cannot be accommodated. Cast aluminum construction provides lightweight strength while resisting corrosion, and the black paint finish matches modern performance brake aesthetics. The 15/16-inch bore size represents a balanced specification for street-driven vehicles, offering adequate brake pressure modulation without excessive pedal effort.

This master cylinder suits builders prioritizing compact brake systems on custom vehicles, including classic muscle cars, custom trucks, and street rods where factory brake components interfere with engine bay modifications. Tandem design ensures redundant braking—if one circuit fails, the other circuit remains functional, meeting fundamental safety requirements for street operation. The universal mounting design accommodates various brake line plumbing configurations, providing flexibility across different application geometries.

Wilwood is recognized for performance brake components engineered to exacting tolerances. This compact tandem master cylinder delivers the brake system control and reliability expected from the brand while addressing the specific dimensional constraints of custom builds where conventional solutions fall short.
