The Wilwood High-Volume Aluminum Master Cylinder, part number WIL260-6765, offers superior fluid capacity and durability for automotive braking systems. Crafted from high-pressure die-cast aluminum, this master cylinder features a lightweight yet robust body designed for high-performance applications. Its high-volume reservoir holds up to 8.2 ounces of brake fluid, providing at least 26% more capacity than comparable models, which helps reduce the frequency of refilling and ensures consistent braking performance. The 1-7/16 inch piston travel offers extra margin for use with large piston calipers, enhancing braking response and control. Heavy-duty internal springs facilitate fast retraction, improving pedal feel and reducing brake drag. The formed steel lid with a bellows-type gasket effectively seals out moisture, preserving fluid integrity and preventing corrosion. Designed with common dimensions for flange or side mounting and featuring a 1/8-27 NPT outlet port, this master cylinder is compatible with a wide range of brake systems, making installation straightforward and versatile. Built for demanding automotive applications, the Wilwood high-volume aluminum master cylinder combines reliability with performance, ensuring optimal braking efficiency under various driving conditions. Whether upgrading an existing system or building a custom setup, this master cylinder is engineered to deliver consistent, high-quality results that meet the needs of serious enthusiasts and professionals alike.
