Wilwood Compact Tandem Master Cylinder w/ Combination Valve 1-1/8in Bore - Black

The Wilwood Compact Tandem Master Cylinder with Combination Valve is designed for automotive brake systems requiring dependable hydraulic control in a compact package. Featuring a 1-1/8-inch bore, this master cylinder provides consistent fluid pressure and responsive pedal performance for custom builds, performance vehicles, and replacement applications. Its tandem design supports separate primary and secondary hydraulic circuits for added braking system reliability.
The integrated combination valve helps manage brake pressure between the front and rear circuits, promoting balanced braking performance and helping reduce the possibility of premature rear-wheel lockup. The black finish delivers a clean, professional appearance while providing a durable surface suitable for a wide range of engine bay and chassis configurations. Wilwood engineering ensures compatibility with properly matched braking components and hydraulic system requirements.
Designed for installation where space is limited, the compact housing helps simplify packaging without sacrificing essential master cylinder functionality. The 1-1/8-inch bore should be selected based on caliper capacity, pedal ratio, booster configuration, and the desired pedal feel. Verify mounting, port, pushrod, and fluid compatibility before installation. Professional installation and thorough brake system bleeding are recommended to help ensure safe, reliable operation. This Wilwood part is supplied as a single master cylinder assembly with an integrated combination valve.
