Wilwood High Volume Tandem Master Cylinder for Early Mustangs – 15/16 inch Bore with Pushrod

Description

The Wilwood High Volume Tandem Master Cylinder (Part Number 260-14157) is designed specifically for early Mustang models from 1964 to 1972, offering reliable braking performance with a 15/16 inch bore diameter. Crafted from high-pressure die castings, this aluminum master cylinder provides a significant weight reduction—about 75% lighter than traditional cast iron units—without compromising durability or strength. Its lightweight design facilitates easier installation and handling while maintaining high performance for manual brake applications. The master cylinder includes a factory-appropriate pushrod, ensuring compatibility with OEM brake pedals and simplifying installation. The design features a stroke of 1.10 inches and a fluid volume ratio of 2:1 between primary and secondary chambers, optimizing brake pedal feel and stopping power. The mount flanges accommodate factory specifications, fitting from 3.22 to 3.40 inches, which aligns with the factory manual brake setup for these vehicles. Fluid outlet ports are positioned on both sides of the bore, enabling flexible plumbing options for custom brake line routing. This master cylinder is available in three finishes—plain, ball burnished, and black e-coat—allowing for aesthetic customization and corrosion resistance. Additionally, Wilwood offers optional accessories such as a combination proportioning valve kit, complete with brackets and stainless lines, designed for seamless integration with this master cylinder (see PN 260-13190 or 220-13189 for retrofit versions). Whether upgrading your classic Mustang’s braking system or building a high-performance street rod, this master cylinder delivers reliable and consistent braking performance with easy installation and superior build quality.
