Description
The Wilwood High Volume Aluminum Master Cylinder with a 3/4 inch bore is designed for high-performance braking systems requiring increased fluid capacity and reliable operation. Constructed with high-pressure die-cast aluminum, this master cylinder offers durability and corrosion resistance, making it suitable for demanding automotive applications. Its high-volume reservoir features a total capacity of 8.2 ounces, providing at least 26% more fluid capacity compared to standard models, which ensures consistent brake performance during extended use or heavy-duty driving. The piston travel of 1-7/16 inches offers ample margin for use with large piston calipers, enhancing modulation and stopping power. Heavy-duty internal springs facilitate quick retraction, contributing to responsive braking feel and reducing pedal travel. The formed steel lids combined with bellows-type gaskets effectively seal out moisture and contaminants, maintaining fluid purity and system reliability. Wilwood master cylinders are designed with common dimensions for flange or side mounting, simplifying installation in a wide range of vehicle configurations. The 1/8-27 NPT outlet port ensures compatibility with various brake line fittings, making this master cylinder a versatile choice for custom builds or upgrades. Engineered for high performance and long-lasting durability, the Wilwood High Volume Aluminum Master Cylinder is an excellent component for racing, off-road, or street applications where enhanced braking capacity and system integrity are critical.
