Wilwood High Volume Tandem Master Cylinder for Early Mustangs, 7/8 Inch Bore, Black Finish with Pushrod * Part Number Wil260-12900-BK

The Wilwood High Volume Tandem Master Cylinder for early Mustangs is designed to enhance brake performance with precision engineering and lightweight construction. Crafted from high-pressure die castings, this master cylinder features a 7/8" bore, ideal for manual brake applications, and includes the factory-compatible pushrod for seamless installation. Its sleek black e-coat finish not only provides corrosion resistance but also complements the performance-oriented design of vintage Mustang restorations and upgrades.
This master cylinder is engineered to fit mount flanges from 3.22" to 3.40", matching the factory manual master cylinder mount locations for 1964-1972 Mustang models. With fluid outlet ports on both sides of the bore, it ensures versatile plumbing options for custom brake setups. The 1.10" stroke and a 2:1 volume ratio between chambers deliver consistent brake pedal feel and reliable hydraulic performance, critical for high-performance driving or heavy-duty use.
Weighing approximately 3 pounds, this master cylinder offers a significant weight reduction*roughly 75% less than traditional cast iron units*making it an excellent choice for weight-sensitive builds. For optimal brake system integration, Wilwood also offers a compatible combination proportioning valve kit, including brackets and stainless lines, specifically designed for use with this master cylinder, available under part numbers 260-13190 and 220-13189 for retrofit applications. This product is built to meet the demands of custom automotive projects and restorations, providing durability, performance, and ease of installation for Mustang enthusiasts and professionals alike.
