Wilwood High Volume Tandem Master Cylinder – 15/16 Inch Bore Black with Pushrod

Description

The Wilwood high volume tandem master cylinder, part number 260-13375-BK, features a 15/16 inch bore designed for enhanced braking performance in manual applications. Crafted from high-pressure die cast aluminum, this master cylinder offers a significant weight reduction of approximately 75% compared to traditional cast iron units, making it ideal for performance and weight-conscious builds. It includes a pushrod and is available in three finishes: plain, ball burnished, and black e-coat, allowing for customization to match your vehicle’s aesthetic. The durable construction ensures reliable operation across a range of domestic cars and trucks from the mid-1960s to the present day, with mounting flanges accommodating widths from 3.22 to 3.40 inches. The design incorporates fluid outlet ports on both sides of the bore for flexible plumbing configurations. With a stroke of 1.10 inches and a 2:1 volume ratio between primary and secondary chambers, this master cylinder delivers consistent brake pressure and modulation. For optimal installation and system integration, Wilwood offers a combination proportioning valve kit, including brackets and stainless steel lines, compatible with this master cylinder (see PN 260-13190 or 220-13189 for retrofit options). Its compact form factor and robust performance make it a reliable choice for custom builds, restorations, and high-performance vehicles requiring precise braking control.
