This aluminum tandem master cylinder is engineered for demanding automotive and industrial applications, offering a lightweight yet durable solution for manual brake systems. Machined from high-pressure die castings, it weighs approximately 3 pounds, providing a 75% weight reduction compared to traditional cast iron units, which enhances vehicle handling and reduces chassis strain. The cylinder features a 7/8-inch bore with a 1.10-inch stroke, designed for compatibility with mount flanges ranging from 3.22 to 3.40 inches, making it suitable for most domestic cars and trucks from the mid-1960s to modern models. It includes a pushrod for straightforward installation and fluid outlet ports on both sides of the bore, ensuring versatile plumbing options. The master cylinder’s dual-chamber volume ratio of 2:1 helps optimize brake pedal feel and modulation, making it ideal for high-performance and heavy-duty fleet applications. Available in plain, ball burnished, or black e-coat finishes, this component offers corrosion resistance and a professional appearance for various environments.
