The Wilwood 260-14959-BK Compact Tandem Master Cylinder is a lightweight, high-performance braking solution designed for both manual and power-assisted brake systems. Featuring a 1.00-inch bore, this tandem outlet master cylinder is suitable for a wide range of custom, retrofit, and performance applications. It is machined from high-pressure aluminum die castings and finished in a durable black e-coat, delivering a 75% weight savings compared to traditional cast iron OE master cylinders.

Designed to fit mounting flanges from 3.22" to 3.40", this master cylinder is compatible with most domestic cars and trucks from the mid-1960s to present. Dual fluid outlet ports on both sides of the bore provide flexible plumbing options, while the 1.10" stroke and 2:1 volume ratio ensure consistent brake pressure across both chambers. An integral dual-chamber reservoir offers reliable fluid capacity in a compact design, making this master cylinder ideal for performance street, restomod, and racing brake systems.
