Master Cyl Tandem 15/16 Compact Black

The Wilwood Master Cylinder Tandem 15/16 Compact Black is a compact tandem master cylinder engineered for high-performance and custom brake system builds where space is premium and reliability is non-negotiable. Designed for street rods, restorations, track vehicles, and modern custom projects, this master cylinder delivers the hydraulic pressure control necessary for responsive brake modulation across dual hydraulic circuits.

The compact profile makes it ideal for engine bays with tight packaging constraints while maintaining full functional capability for both front and rear brake circuits. Built with Wilwood's signature engineering, the 15/16-inch bore configuration balances pedal effort with hydraulic output, making it suitable for both naturally aspirated and boosted applications depending on your brake line sizing and proportioning setup.

The tandem design incorporates dual independent pistons and seals to maintain separate pressure paths—critical for safety and brake balance tuning. Weighing only 3.23 pounds, this cylinder reduces unsprung mass while its compact black finish resists corrosion and maintains a clean aesthetic. Technicians and enthusiasts favor Wilwood master cylinders for custom brake system integration, particularly in applications where OEM units don't fit.
